Shanling UP2 vs UP4 Review

In this review our “new guy” Yagiz takes a close look at the Shanling UP2 vs UP4, priced at $79 and $99USD! Let’s check out these quite special units.

 

 

Disclaimer: Shanling have sent us both versions for the purposes of the review free of charge, I only covered the import taxes and fees. All thoughts and experiences with the product are naturally my own. Headfonia and Shanling are not related in any way. 

Note: This is Yagiz’ very first review for Headfonia. Let’s give him a warm welcome!

Hello fellow aficionados, I am Yagiz and this is my first review here on Headfonia. I aim to share my experiences and hopefully will help you make better choices. I will be focusing on wireless devices so stay tuned in! Without further ado, let’s dive in and see if these BT DAC/AMPS are worthy companions for your trips!

Shanling

Founded in 1988, Shanling has been developing Hi-Fi products for more than 30 years now. From high-end CD player to classy tube-amp, the brand made a name thanks to great craftsmanship and top of the line performances.

These past years, the brand also developed a complete range of portable players and IEMs. Just a fe days ago we reviewed the Shanling M6, a great DAP in our opinion which we immediately listed as a recommended buy. Today we’ll be reviewing their new wireless “DAC/AMP” units, the UP2 and UP4.

What is a Bluetooth amplifier exactly and why does it exist?

Well, in my opinion the most important market introduction was seen when Astell & Kern released their XB10 into the market. I was skeptical, as always, but went on and bought one. The first days using it the XB10 did not really impress me but then I had to use a lot of trains. Lots of people and chatter in a confined space, you get the idea. And that’s where the concept of the Bluetooth amplifier really comes in handy. I was storing my in-ears (Earsonics S-EM9 at that time) with thick braided cable around the Bluetooth amp to keep them together, plugged in. Ready whenever, without the need of plugging it in and out, without the need to reach my phone. At that time it felt perfect, even though the size was an issue.

That just was the form factor side of things though, let’s look at it from an audiophile standpoint. Yes,  I am well aware that Bluetooth audio capabilities are still somewhat limited but if you’re aiming for casual hifi listening sessions on the go, which may include some kind of streaming service such as Tidal, it should/could be enough. Current LDAC cap is 990 kpb/s which is around the level of CDs, but it’s not quite there yet. Of course these DAC/AMPs, compared to a smartphone, deliver a much better sound quality thanks to their proprietary DAC/AMP designs. Not many people want to walk around with two blocks of smart devices in their pocket however, so most audiophiles started using dedicated DAPs on-the go. The big advantage: sweet and sublime sound quality. But now times might be changing again and some users will surely adapt to these new smart devices, leaving the DAP out of their pockets.

Anyway it means it’s time for us to have a closer look at two of the newer wireless DAC/AMPs on the market.

    There is an important difference between the UP4 and UP2, UP4 has a symmetric output which makes the sound more natural and transparent. I recently compared the Fiio BTR5 and BTR3 which are technically a similar pair of devices as Shanling’s Bluetooth players, however BTR 3 has a less capable DAC as BTR5, which has the same DAC as UP4 and UP2.
    Anyway congratulations for your first review and Best Wishes for the future…

    Thanks for the review! I’d appreciate a comparison between the UP4 and the BTR5. I’m in the market, and I think those are more direct competitors than the UP2 and UP4.

    I purchased the Beautiful Audio’s Grado headband and earpad mod and WOW!!!
    Love them. Highly recommended.
    Soft, comfortable and sound wonderful.
    I always found the default Grado earpad uncomfortable to wear after a short time.
    These are soft and deeper leaving my ear in an open space surrounded by a soft comfortable pad. Mmmm, can now enjoy the Grado for extended period of time.
    I have the Grado Heritage Series, cocobolo GH2. and the slightly dark brown leather I choose is a perfect match, aesthetically.
    The headphones now have a very high end look as well as sounding better.
    Thank you Silvian for a such a well made, good looking product.
