I sold my Burson dac/amp wanting a change for HD800S, I demoed NEO and really liked it, I bought one.
Its able to drive them single ended quite easily but I picked up a balanced cable and use that now.
Pretty exceptional driving power for a 5v power supply when running balanced.
When I compared the ifi Diablo to an HDVD800 (sennheiser amp), I spent hours and hours comparing the two, my take away was they were the two closest sound signature amps in my life of comparing amps.. (of course I had the enjoyment of using the Diablos included XLR cable into the back of the HDVD800)
When comparing the HDVD800 vs a Burson Conductor, the HDVD800 renders bass notes clearer and with more impact when gaming, say, "Hunt:showdown" (awesome internal sound renderer for 'headphone surround'), at a middle distance on out, the advantage went to the HDVD800.
The fact that the Diablo (the portable version of the Neo, arguably) clearly has the performance equality to the HDVD800 (an
exceptional amp if it can hold its own against the top of the line Burson), and a better DAC than both those parts (but fair given the few years in history between each of these components releases); the Neo/iFi amp section in these price point parts is 'outstanding value'.
To my knowledge the biggest disadvantages of the Diablo (vs the Neo) are the cut down in size jacks (eg to use COAX I need use an adaptor cable, to feed in Toslink, I need use an adaptor cable, to feed out to a regular stereo I have to feed the XLRs into another unit that can do channel matching (like a Grace Design m903) etc).
The desktop component, the Neo, makes for a much better use for those that do not need the portability.
And whilst users here might not fully appreciate the adaptors included with the 'performance edition Neo', the amount of times I would have bought that iFi SPDIF purifier had it been in store at my local head-fi retail outlet is ridiculous.
iFi tech (trickle down stuff from mega budget AMR stuff) is fantastic value for money.
The Diablo cannot do GTO on the SPDIF input, to the best of my understanding, and is one of a few niggles that I have always hoped would come to the Diablo..(firmware updates perhaps)..
Internally the way the XMOS controller handles digital inputs, might not allow this..
So the Neo, from a usability point of view is definitely the part to buy into..
It has all the ins and outs that a part could want.. and basic stuff like being able to use nice RCA/'phono' plugs that I have lying around...
Per iFi incredible support ethics, the fact that existing parts get new firmware updates and features (eg Sony would seldom do that if it meant they could sell 'a new unit') the company just delivers on the fronts that matter to consumers.
It is strange when we look at the last few pages of this forum how a simple piece of advertising literature can get us caught up/fearful/worried about 'fair value' and whether we will get something we hoped to do so.. and with the exception of iFi forum reps not being clued into all internal firmwares coming out and which products get them, literally being one step behind us 'eager consumers' who are willing to test unofficial firmwares from 'other iFi products'; the nature of iFi always sharing the best software (firmware) they have to previous models is 'a thing' (and a reason to support a pro consumer/'pro 'end user' company.
If we recognise that having bitperfect AND GTO and easy ability to switch up the settings etc,. this is a top of the line DAC and owns this market segment.
When comparing to things like a Denafrips (an incredible home hifi DAC), the lack of a lot of options on the Denafrips (And nightmare to change filters etc) starts to show.. what we invest in with the Neo (at a significant price difference to parts we are putting it against, themselves class leading and 'exceptional value for money' against parts many times the cost), the fact that the parts can hold a compete at all is incredible...
As someone who recognises that the GTO filter alone is a reason to have an iFi part in a system, and wanting the cleanest, most user friendly iFi part that money can buy..
iFi
are a refreshing 'glass of water' in a market filled with sharks and sometimes 'snake oil'.
Just in the time I used a Diablo, the added features through firmware updates, like Playstation 5 console support, were always gifts to receive..
And for users who buy a DAC, a year of its lifetime, perhaps waiting for a new featured firmware, when considering the total life of the product.
Heck I am happy using 10 year old DACs, and
I know iFi support products well beyond their warranty period. (most of the big consumer electronics companies DO NOT)
Congrats iFi, nice refresh on the Neo to keep a modified price point (everyone knows how hard the commercial market must be based on the last few years), and giving tech toys that not everyone might know about, but that will certainly improve sound on devices of this calibre when fed into higher tiered audio setups.
(the iFi parts truly do 'punch above their price point' with respect to their performance and output quality (and features))
As someone who has bought multiple iFi accessories, such as USB filters and AC purifiers, and loves the iPower power packs etc.. opening iFi product boxes always makes me smile when I see that nice smiley face....
