Review: Fiio X5 Second Generation Part 1

Disclaimer: I, Lieven, asked Paul (aka Brooko on Head-fi) to do a double review with me on Fiio’s latest DAP, the X5 Second Generation. Because of the length of this very in depth review I will be posting Part 1 today (Paul) and Part 2 (Lieven) tomorrow. I, in no way changed anything in Paul’s review. Be warned, it’s a looong review. Paul, take it away.

Fiio X5 (2nd Generation) – Incremental Gains & Still Great Value For Feature Set.

INTRODUCTION

I’m a very happy owner of Fiio’s X1, X3ii and the original X5 digital audio players (DAPs). I’ve used them all (a lot) over the last couple of years – and up until now, the X3ii has been my go to portable DAP for daily use. I still use the X1 for ultimate portability (eg exercise), and the X5 when I need a more power, mainly when I’ve been using full sized headphones. I’ve been using Fiio audio equipment for close to four years now (amps, DACs , and DAPs), and have watched them evolve in that time from a fledgling audio company to a serious player in the personal audio world. A couple of things have stayed constant in all of my time using Fiio products though – they’ve always strived to improve their performance, and they’ve always aimed to release audio products that measure well, sound great, and offer real value for money.

After seeing the improvements Fio made recently upgrading their X3 DAP to the X3ii, naturally I was keen to also see the changes in the transition from X5 to X5ii. So I arranged with Joe to organise the Fiio X5ii “Down Under” tours, and we now currently have two units touring through Australia and New Zealand.

ABOUT FIIO

By now, most Head-Fi members should know about the Fiio Electronics Company. If you don’t, here’s a very short summary. Fiio was first founded in 2007. Their first offerings were some extremely low cost portable amplifiers – which were sometimes critiqued by some seasoned Head-Fiers as being low budget “toys”. But Fiio has spent a lot of time with the community here, and continued to listen to their potential buyers, adopt our ideas, and grow their product range. They debuted their first DAP (the X3) in 2013, and despite some early hiccups with developing the UI, have worked with their customer base to continually develop the firmware for a better user experience. The X3 was followed by the X5 (now former) flagship DAP – which despite its reasonable cost (300-350) has been able to compete with models from other manufacturers costing hundreds of dollars more. They then released the X1 – an ultra low cost DAP (~USD 100) which has done even more toward bringing high quality mobile audio to those on a tighter budget, and more recently the X3 2nd Generation (X3ii), and upgrade on the original X3 from 2013. Fiio’s products have followed a very simple formula since 2007 – affordable, stylish, well built, functional, measuring well, and most importantly sounding good.

DISCLAIMER

I was provided the Fiio X5 second generation as a review sample. It will go on tour once I have finished reviewing it. There is no financial incentive from Fiio in writing this review. I am in no way affiliated with Fiio – and this review is my honest opinion of the X5 second generation. I would like to thank Joe & James for making this opportunity available.

PREAMBLE – ‘ABOUT ME’.

I’m a 48 year old music lover. I don’t say audiophile – I just love my music. Over the last few years, I have slowly changed from cheaper listening set-ups to my current set-up. I vary my listening from portable (mostly Fiio X3ii and iPhone 5S) to my desk-top’s set-up (PC > coax > NFB-12 > LD MKIV > HP or PC > USB > iFi Micro iDSD > HP). I also use a portable set-up at work – either X3ii > HP, or PC > E17K > HP. My main full sized headphones at the time of writing are the Beyer T1 and Sennheiser HD600. Most of my portable listening is done with IEMs – and up till now it has mainly been with the Fidue A83, Dunu Titan, Trinity Delta, and more recently DUNU’s DN-2000J. A full list of the gear I have owned (past and present is listed in my Head-Fi profile).

I have very eclectic music tastes listening to a variety from classical/opera and jazz, to grunge and general rock.   I listen to a lot of blues, jazz, folk music, classic rock, indie and alternative rock. I am particularly fond of female vocals. I generally tend toward cans that are relatively neutral/balanced, but I do have a fondness for clarity, and suspect I might have slight ‘treble-head’ preferences. I am not treble sensitive (at all), and in the past have really enjoyed headphones like the K701, SR325i, and of course the T1 and DT880.

I have extensively tested myself (abx) and I find aac256 or higher completely transparent. I do use exclusively redbook 16/44.1 if space is not an issue. All of my music is legally purchased (mostly CD – the rest FLAC purchased on-line). I tend to be skeptical about audiophile ‘claims’, don’t generally believe in burn-in, have never heard a difference with different cables, and would rather test myself blind on perceived differences. I am not a ‘golden eared listener’. I suffer from mild tinnitus, and at 48, my hearing is less than perfect.

My experience with DAPs in the past had been initially with some very cheap Sony offerings, then step-ups to the Cowon iAudio7, iPhone4, iPod Touch G4, iPhone 5S, HSA Studio V3, Fiio X5, X1, and X3ii.

WHAT I LOOK FOR IN A DAP

I thought I’d list (before I start with the review) what I really look for in a new DAP.

  • Clean, neutral signature – but with body (not thin)
  • Good build quality
  • Reasonable battery life
  • Easy to use interface
  • Able to drive both low impedance and (within reason) higher impedance cans without additional amping.
  • Value for money
  • Enough storage to hold either my favourite albums in redbook, or my whole library in a reasonably high resolution lossy format (for me – aac256)

Did I get all of this with the X5ii, and more importantly was the X5ii an improvement on the original X5? Mostly – yes, and I hope that the shortcomings with the firmware will be improved over time. Fiio has shown commitment to the Head-Fi community in the past – in trying to improve the Fiio experience with better firmware releases over time.

This is a purely subjective review – my gear, my ears, and my experience. Please take it all with a grain of salt – especially if it does not match your own experience.

THE REVIEW

From this point onward, I’m going to simply call the Fiio X5 2nd generation the “X5ii” – as much for ease of typing and understanding than anything else.

PACKAGING AND ACCESSORIES

The X5ii arrived in a rather sombre looking black outer box, with the now traditional black inner box and lid nestled inside. Gone is the texturing on the 2nd box though – now it is a simple black matt with the Fiio logo subtly shown on the front. I love the simplicity of it. Note – this is not the final packaging though. Opening the box reveals a foam inner form fitting mould, with the X5ii nestled securely inside, already in its black silicone case – in turn covered in a plastic protective cover. Also included is a single card explaining the layout of the main features.

Underneath the foam (which lifts out) there is a thinner secondary box which holds the accessories which include:

  • A USB charging / data cable
  • A digital out to coax cable
  • 2 spare screen protectors for the X5ii (plus one already prefitted)
  • 3 different patterned sets of stickers (for personalising your X5ii) – wood grain, carbon and USA.
  • A foldout warranty card
  • The Fiio X5ii quick start guide

The entire package is practical, covering everything you initially need for the player. Materials are all good quality. What is missing (IMO) from the original X5 is the small Fiio USB card reader – which I have found extremely handy over the last couple of years.

Paul is a Kiwi from Down Under (New Zealand) and spends his time selling Lamb by day, and playing round with audio gear by night. He's a self confessed music junkie, with wide musical tastes and a penchant for female vocalists. He is not a golden eared listener, prefers to review armed with an SPL meter and objective measurements, and does his best to balance objectivity and subjectivity. Mostly though, he can be found with headphones on his head, and a smile on his face - lost in the moment.

      Volume has no effect (as it shouldn’t – being a fixed line-out). I’ll get Lieven to answer on the gain as I honestly can’t remember, and the X5ii is currently on tour in NZ.

      I think I understand the UI from reading this, but just wanted to clarify the search. I have all my tracks on i-devices (w/o folders) named as “Artist – Songname”, and tagged the same way for sorting in the music player. So on the i-device, to go instantly from “Lecrae – Falling Down” to “Julia Holter – Boy in the Moon”, I press the “J” button** and do a 1 to 2 second scroll and there I am. So with the FiiO, would you have to first change folders and then scroll? I wonder how long it would take to do what I described?

      **Actually when I need Julia etc. on the i-device, I usually press “K” and scroll backwards, since it’s closer.

      • Reply June 16, 2015

        Brooko

        Hi Dale. There is no search function as such – I simply use folder view, with a hierarchy system to make the scrolling a lot less. So I have things folder sorted alphabetically into groups of 3 (A-C, D-F, G-I etc) – so 8 first level folders. Underneath that is the artist folders. Under those are the album folders. I have around 400 full albums on the X5ii, and can get to an albun within a matter of seconds using this method.

      This is a really thorough review – thanks for taking the time to do it, Brooko, and thanks for sharing the nice hi-res pictures!

      I would like some advice. I’ve only used ipods as DAP’s and am ready to either amp it (as I’ve got HE-400’s that sound pretty weak with just the DAP) or buy a separate DAP that I would use for everything but gym listening.

      I’m looking for a portable solution that I’ll use primarily at home when I want a relaxing listening session. The only headphone amp/DAC I’ve had experience with is the Meridian Explorer, which provides plenty of power to the HE’s. I’d like to find a similar experience using a DAP as a source.

      Would you suggest a new DAP? Amping the iTouch? Thoughts?

      • Reply June 15, 2015

        Headfonia_L.

        I would suggest CLAS SOLO and Duet amp if you like using the ipod/pad
        I resized brooko’s pics and did some retouching 😀

        Thanks. I know there are plenty of Apple nay-sayers out there, but I’ve always rated the later i-Devices pretty highly as far as sonics go. They’re just limited on expandable storage space and power – which is where the Fiios excel. Hard to go past the Apple UI though.

        I guess it depends on what you’re looking for, and what features you value. I personally haven’t heard a lot of the “increased dynamics / bigger sound stage etc” that a lot of reviewers talk about when adding amplification. To me – an amp changes 3 main (useful) things : impedance (useful if you have a higher impedance source and sensitive earphones), hardware EQ controls (eg bass boost), and most importantly and increase in clean and constant power (voltage & current). If your headphones need more current or voltage than your DAP can supply – which I’m guessing you need with the HE-400s, then that is where the amp will be necessary.

        For a nice portable solution – I always really liked the Headstage Arrow series, but if you’re going to be spending $300 on an amp, then it may be better to just look at something like the X5ii (and no amp) because you will get argaubly better SQ and features. For a cheaper solution – even the Fiio E11K supplies very good clean power.

        I’m not sure if Lieven has the HE400, or access to one? If he does, maybe he can try it with the X5ii, and tell you what he thinks.

          My iPhone 6-plus sounds better than my iPhone 5 and iPod Touches. But adding the Oppo HA-2 gains me very little over the phone alone, and my older Verza isn’t as good as the HA-2. If someone asked me, I’d say get a much better amp, or skip that and get the DAP.

            …. by much better amp, can you give a few suggestions? Looks like Lieven (or the person who might be Lieven below) recommends Cypher labs’ stuff.

      thanks for the thorough review, it looks like a very complete dap. soo any comparison with ibasso and other daps would be out of place?..also i’m curious how the amp section compares to E12/E12A.. and..would a X3II paired with a E12A give better sound? many questions, i know XD

        Hi llias – thanks. If you wait for Lieven’s follow up tomorrow, he has a section on his comparison with the iBasso DAPs. I’m yet to hear an iBasso – but will try at some stage to get hold of one for future reference.

        Brooko

        Thanks. It’s a step-up from X5 original, but its incremental rather than exponential, or evolution rather than revolution. The X5ii (IMO) still represents extremely good value for money – especially compared to some of the other boutique offerings.

          I think unless you absolutely need to have the X52G or you never owned the 1G, then perhaps you could give it a miss. Unless $350 is no skin off your nose.

            What other DAPs are you comparing with, what headphones have you had experience with (with X5 and X5ii), and what is your rationale behind this comment? Genuinely curious 🙂

              Observer

              OK.
              I have owned several DACs in the FiiO range and have absolutely no issues with any of them. Except perhaps earlier models had a bit of background hiss.
              My reference headphones are the Shure SE846CLs. Even my Oppo PM-3s don’t come close. But different strokes…

              I also purchased the Oppo HA-2, but to me, the FiiO E12A sounds better when paired with the FiiO X5. But all I am commenting on are my own personal preferences and opinions.

              Your taste in music may vary vastly from mine.

              I am a Jean-Michel Jarre, Andreas Vollenweider, Darshan Ambient, Tangerine Dream, Art of Noise, Jimmy Smith, Eric Gale, Herb Alpert, Barry White, Herbert von Karajan (with Berlin Philharmonic Orchestra), Beethoven kind of person.

              The review is well written and if I can get a buyer for my X51G, I will go for the 2G, but for now, I can play DSD256 with an iPhone 6 and HA-2 quite happily paired with my Shures.

              Just my opinion sir.

          I have a choice (both new to me) of the Blue Mofi with the built in amp or the B&O H6. I’ve read up on both so hoping at least one of these matches well with a new DAP (leaning towards an X5II purchase).

              Will do. I’ve heard that both headphones are not bass-centric and have a balanced sound across the spectrum with a fairly wide soundstage. I’ll send some feedback once I have some time to break these all in.

                      Loved the 325 when I had one. Always regretted selling it. Mine was modded quite a bit though – full wooden jacket, leather headband, mogami recable. I actually liked them more than the RS1 I had.

                        I got the Brooklyn Tree (GH1) woodie recently. A little darker, more mellow than the 325e, but more uneven in the treble. Unless it flattens out some after the 150 hours already played.

                        I thought about trying the RS2 and seeing if that was closer to the 325 than the RS1 was. I think if I ever end up getting another Grado, it’ll be RS2 or 325 again.

                The H6 has some definite bass emphasis compared to the Senn HD600, but it’s a very solid bass with no bloat or mud.

                  I may have to tweak my EQ for the H6s. The Senn HD600s might have been a better choice for less bass emphasis.

                Actually – the reviewer (me) points out good points and bad, doesn’t mention prettiness or sound stage (IMO with DAPS, the headphone has more influence on the soundstage than the DAP does), and actually says that its an incremental rather than exponential upgrade. I’d love to be able to review the AK Junior against it – but unfortunately I don’t have one, and at this stage no interested in buying one just for a single review/comparison.

      this is the (my) problem

        The Momentums aren’t difficult to drive, and if you’re mainly using them on-the-go, I’d probably recommend staying with the X3ii. It’s cheaper, smaller form factor, and you’d be unlikely to kiss the lift in fidelity (particularly if most of your listening is portable). If on the other hand you plan to use the DAP also as a DAC, and as part of an integrated system, and if space (dual slots) is needed, then the X5ii has the upper hand. At the end of the day – I’d pick first on the feature set you need.

      Reading on the train, so may have missed it but how does the sound compare to your Micro iDSD?

      Does it need to burn in to sound better? What is your take on it?

      Is it known if you can do more than the 128GB for each slot?

        I haven’t tested it myself but it should be ok. The guys on Headfi also know more about it

      I have X3 2nd gen. Is it a wise idea to upgrade to X5 2nd gen or is it worth the upgrade. If the difference is too little I would like to be satisfied with my X3. Kindly suggest

        wanna ask the same thing. planning to get an x3ii if the x5ii is not really a big step up for IEMs which aren’t power hungry.

      sorry, but it would be nice if you can answer just a question, i have a X1 1st generation on may way and I have a Senheiser Amperior, Now i have the chance of getting a cheap (in my country these gadgests cost more than twice) X5 2d generation.

      So my cuestion is : Do you think i would get a noticeable difference between the X1 and the X5II?

        Of course there’s a huge difference. That’s logic.

      I am very new to the DAP world so please forgive my ignorance. I’ve been doing a lot of reading but still can’t seem to get the answer to my question, and you folks combine the technical skill with the real-world knowledge I look for in a reviewer.
      So, here’s my question: I recently ripped my modest collection of CD’s to FLAC using DBPoweramp (great tool by the way) and I have a little over 115GB of content I’d like to play on my tried & true (read ‘old’) receiver/amp and tower speakers. Are the Fiio DAP’s (X5iii and X3ii) a good answer for this, or should I be looking at a different solution? Portability is not that important to me, but getting good sound quality out of my music is.

        You can always find something that’s better, but try to maximize what you have first. Impedance matching, amount of gain, fine tuning for the gear and the room are all factors you should address.
