CHANGES FROM ORIGINAL X5
Fiio lists the following as the main improvements of the X5 2nd gen over the X5 original.
- All new exterior design, improved build, and metal finish changed from powdered to brush
- Smaller and lighter
- Reduced black borders around LCD
- New independent amplification stage with analogue volume control – increasing audio resolution
- New digital audio architecture utilising dual crystal oscillators dedicated to multiples of 44.1 and 48kHz respectively (to handle all major sample rates without resampling artifacts and minimal jitter)
- Hardware DSD decoding
- Supports CTIA standard in-line earphone remote control units
- New power architecture design that utilises different system voltages for low and high gain – allowing maximum flexibility between endurance and power.
- Standby mode – allowing player to remain in standby for weeks, ready to continue playing instantly when activated.
- Coulomb meter for precise battery level readouts.
SPECIAL NOTES ON PREVIEW UNITS
When reading this review, and remembering this is a preview unit, it should be noted that the following changes are still to be made by Fiio before release.
- Packaging will be changed to full retail ready packaging.
- Side control buttons will be manufactured slightly differently to improve tactile performance
- Scroll wheel will have a higher damping factor – similar to the X3ii – for more positive tactile feedback.
- Firmware will be likely to change before final release – but this will be ongoing.
Like all of Fiio’s recent releases, the build on the X5ii (IMO) is excellent for a DAP in this price range. The casing is a 2 piece high quality CNC aluminium alloy with a very nice gunmetal shade and brushed finish. I see no blemishes on this unit – everything fits extremely well together, the corners are smooth, but I did notice the front face beveling is angled rather than rounded (similar to the original X5). Both the X1 and X3ii are rounded, and I have to admit I actually like their appearance and feel a little more when held.
One of the first noticeable physical changes between the original X5 and X5ii, apart from the colour, finish, and slightly smaller dimensions, is the very flat “sleek / modern” look of the X5ii. It still has the wheel and 5 front navigation buttons, but this time everything is on a single plane – and quite flat/flush – where on the original X5, the wheel, buttons and screen were all raised. Because of this, the buttons are less likely to be jogged or pressed accidentally. In fact on this unit, the front buttons are actually very flush – which I see as a good thing.
The front buttons themselves are smaller, round, but have roughly the same tactile response, and I have no problems with accidental pushes, or with locating them. The buttons are labeled with white etching in the metal work of the case – but of course this disappears if using the supplied cover. The button layout is very consistent with Fiios other DAPs, and if you’re familiar with the X1, X3ii, or even original X5 – it won’t take too long to know exactly where you are. I find the front buttons ideally located for easy one hand operation.
