At this point in time I'd say buy neither. I have both the 808 and the Vibez among... well, a few others. Just because I've not been posting on Head-Fi much doesn't mean I've been remiss in my DAP-buying
Admittedly I don't use the 808 anywhere near as much as I should, because Sonicstage (which I'll refer to hereafter more accurately as Chronicstage) is just a complete joke compared to any other media management / loading software out there, opinions of users with perhaps twenty anime albums in their entire collection and long-term Sony fanboys notwithstanding. As I've said elsewhere, running on one of my overclocked quad-cores it behaves like the current (behemoth) iTunes would on a four-year-old PC. Also, the 808 is not demonstrably superior to the Vibez in terms of SQ... or many other players for that matter. And that's not arrived at through a hurried, uncontrolled and biased test in the 7 days that you have to return a player
, and also the way that Sony engineers the 808 makes it slightly more difficult to arrive at a "level playing field" conclusion.
The first problem with the NW-A808’s sound is that it once again has the bass hump for a supposedly 'flat' setting, a level that appears higher for ATRAC than MP3. It could be argued that this is not a ‘sonic signature’ level but a somewhat more deliberate decision to affect decisions at the psychological level, but I won’t get too much into that. Also because the 808 itself doesn't play back lossless formats it's not really possible to give the Sony player a totally fair shake either way. The slightly modified 'flat' signal gives it either an unfair disadvantage or advantage depending on the listener simply because there’s a very slight difference, and while others are playing back Lossless data the Sony is incapable of matching that level of performance.
Perhaps as a result of the abovementioned shenanigans, the core sound quality of the Sony in comparison to the Vibez is just a tad behind. A tad less clarity, a tad less openness. Thing is though as a standalone - i.e. without reference to software, loading, etc - player for regular compressed files, I really, really like the Sony. The controls are logical. It has excellent menus without doing anything weird. And it's just got that sexy polished feel about the entire device with very solid build quality and some really nice touches in the interface that makes the Vibez look like a DIY product. The screen is gorgeous and the way the interface is shown on it far outstrips other players in terms of ‘now that’s
nice’. It's just that in an everyday, real-life situation with a music enthusiast in comparison to the other players it's significantly more infuriating to load and unload. And unlike a large-capacity player, you will be doing that much more often and I believe it’s the main deal-breaker. It certainly is for me.
Onto the Vibez. OK – so it does FLAC, Ogg, etc and it’s gapless. Which is great. It has the parametric EQ. So what happens when you put FLAC on this thing to enjoy it at its best? Track gaps. I’m not talking gaps between the tracks. I’m talking about gaps *in* the tracks. Every time the HDD powers up to fill the buffer (which is when it needs to, not in-between tracks), it cuts out the sound for a good quarter-second. It’s the same problem that the Karma had in terms of the buffer-fill blip, only much, much more noticeable. Unfortunately the Vibez seems to have very similar audio issues to the Karma in general, even down to the essentially useless Auto Gain control. It is a very respectable player though when it’s not exhibiting these problems, and FLAC playback certainly puts it over the Sony in terms of fidelity, and even compared with similar lossy material the Vibez indicates itself as the slightly better-quality source. The Vibez also has some interesting spikes in the highs when you look at the “flat” plot, although it’s harder to say if this is deliberate or not. But the fact that it doesn’t play back high quality material properly is a major minus factor, which I hope will be fixed with a firmware upgrade.
It’s also not quite a shoehorned Karma + recording + radio, and it has lost one of the Karma’s best music-related features – the on-the-fly playlist generation (that's full playlist creation and editing on the fly, not an on-the-fly playlist as iPod users may assume). It’s also not quite as easy to use as the Karma was. I think by switching to a giant wheel with an integrated 4-way pad, they've taken away some of the natural usability that the Karma's controls had. Provided you were right-handed the Karma had one of the better examples of human interface engineering (if not the best control build quality) out of players to date, and the Vibez has diluted that somewhat. On the plus side, the Vibez is among the fastest-to-load MTP players I've come across and it is also quite refreshing in how it doesn't crash while transferring every few connects or so. There do seem to be a few DRM problems, and I might have a bit more to say on that but if you're on unDRM'd music then it should be very nice and quick. And those VU meters, especially in the amber colour scheme… once you’ve had it, you can’t go back
Eh? What’s the D2 doing there?
If I were you I would include the iAudio D2 in the list of players to consider if gapless is not a critical issue, because the D2 is not gapless. I do matched listening tests - the headphone volumes of each player being compared is matched to less than 0.5db when possible, <1db if not to get rid of the possibility of amplitude changes interfering with the SQ assessment, and in this particular case the volume difference between the players for the test listening tracks were within 0.2db’s. The D2 bests the Sony by a slightly higher margin than the Vibez in terms of fidelity, although the Vibez kicks up the highs a little adding to a teensy bit more splashiness / texture up top.
Are any of the players unacceptable in terms of SQ for everyday, compressed-file use? I think absolutely not, all are fundamentally competent players. But the best among these for
fidelity with high-bitrate materials out of the headphone out seems to be the D2.
The fact that I think the D2 is slightly better sounding than these machines is not to say that the D2 is a best-of-breed player. It's merely one of the better players on the market SQ-wise so you can infer what you want out of that. But that, I have to tell you, surprised me (or maybe it shouldn’t have, knowing Head-Fi) given the hype over the Vibez. If you’re the sort of person who considers a balance of everything – features, core sound quality, usability, and demands competency in all of those aspects but gives a heavy weight to sound quality, I would say that the iAudio is definitely worth looking into. It’s got a very decent core sound quality in all codecs, along with the ability to change the flavour as you see fit. So you can have your cake and eat it, unlike the Nano for example. Featurewise, few other players can beat this thing right now. And it is pretty usable once you get past having to use your nail to prod controls, as the touchscreen does give you some interface advantages.
The 808 is closure for me of sorts – this is probably the last Sony I’ll be given, as opposed to actually going out and buying one. I do hope one day that there is a Sony that I find is worth actually buying after a comparison, because I think their hardware guys still haven't lost their touch and the 808 could be the best piece of portable hardware to come out of Sony as of late. Every hardware and firmware aspect of this has been sweated over and it really shows – purely when considered as a standalone player it is absolutely one of my all-time faves. It's just that their software and legal guys have never had the touch to begin with and that screws the pooch for the 'whole player experience'. The fact that it doesn’t actually exhibit any notable superiority in terms of actual sound quality in comparison to many other players out there is another mark against it as a clear ‘Head-Fi’ contender.
The Vibez’ problems in the audio department with source material which actually justifies the hyped playback quality of this device, allied to the fact that it’s not got the stand-out best audio stage out there reveals the Vibez to be not a panacea for SQ-maniacs, unless perhaps you want to
believe it's the best (And there are at least a couple of players out there for which I could say the same thing – and one of them has a digital amp) as many of you out there already have done. The shortest battery life here by a notable margin also marks it down a notch. In terms of design, UI, etc the Vibez didn’t make anywhere near the impression on me that the Sony did, but nevertheless it’s competent and the battery is replaceable (although as in the case of other superceded players with replaceable cells, it remains to be seen whether the cells remain available).

Coming back to the start, you can probably see by now what I mean when I said I wouldn't buy either. The Vibez deserves credit for bringing back the Karma in a slightly more modernised form... but I think it’s taken a step back in several areas. And the Sony... a potential surefire hit is crippled by Chronistage. There are better packages on the market depending on what you want, and I would say that one of those options would be the D2. And I don’t think this is everything I have to say about the Vibez or the 808, but in the interests of the post becoming out of context I’ll put this much out there now.
