I got this cable second-hand on the FS section here. It was a somewhat spontaneous purchase since I saw it listed and decided to just give it a try. 
 
Build/comfort:
I rate it rather low here because it is very, very stiff and hard to manage. It stays tangled even though it wants to spring apart. I suppose this is because of the nature of the silver-over-copper wire, along with the teflon coating. It is not pliable or rubbery at all and therefore doesn't resist tangling despite its springiness. Also, it's highly microphonic. The stock TG!334 cable has been reported to be microphonic as well, but this is at least twice as severe, maybe more. Any bump on the cable transmits a large thump to the ears, so it's not very practical for up-and-about use. The Fitears are basically turned into a stationary use IEM with this cable. Another factor which exacerbates this is the omission of a chin slider, which would help counteract the cable's tendency to spring away from behind the ears. I purchased a cheap aftermarket clip on slider which is of great help.
 
Sound:
The good part-- I won't get into debating the sonic benefits/non-benefits of cables on head/earphones, but I detect a noticeable broadening of the soundstage, and a bit of treble sparkle added to the sound. Perhaps the bass gets tauter too. Overall, it gives a bit of airiness and detail to the Fitear's sonic presentation. Quite a nice surprise. I normally harbor a bit of skepticism when it comes to how much ultimate difference a cable can make, and so had a pretty reserved if not doubting attitude about this cable. A while back I had a silver cable by another large designer/manufacturer for my customs, and I didn't hear much difference, so I was nicely surprised by these observations with the ALO SXC 24. 
 
Conclusion:
Whether or not it's worth the retail asking price of approaching $300 is up to a user's expectations for a cable. I don't think I'd spring for full retail, but at the lower second-hand price I am glad I purchased it. The sonic improvements I hear just add to the already great TG!334s. 

**Fitear To Go 334**
 
It's very expensive, it doesn't fit the best due to its huge shell, yet I love it all the same. The sound is sublime.
 
Normally I prefer dynamic IEMs for their weighty low end and texture that most BA earphones can't touch, but the tonal quality, transparency, and high level of detail retrieval bring the Fitear to the top of my list. The openness and clarity are really something else for IEMs. They're *almost* as spacious and enjoyable as my modded T50RP orthos. 
 
Bass:  Very good depth and texture, having a punchier tautness than most dynamics I've heard, but doesn't quite have that ultimate slam and extension. However one small tick on an EQ or bass adjust nicely adds weight, and even when listening rather spiritedly I've never once heard a driver clipping which has happened with every other BA I've owned.
 
Midrange:  Stunning, detailed, layered, full and lifelike. I've never heard any earphone (BA or dynamic) with the natural richness these have. I feel this is the biggest strength of the Fitear. 
 
Treble:  The top end has awesome tactile feel, with cymbals having a true palpability and shimmer. However the utmost extension has been noted by others as not quite the best. Personally I don't find anything at all lacking as all my music collection sounds completely natural with no aspect shorted in the least. I do note that my MK2 GR07s give the impression of a touch more extension and shimmer, but I wonder if it's possibly at the expense of being slightly artificially boosted. Hard to say.
 
Soundstage:  Or 'headstage' shall we say... It's definitely sizable for an IEM (some owners have said they feel it's bit intimate rather than super-wide). So perhaps not the last word in ultimate width, but I've never heard spatial cues and instrument placement done so well in any IEM. That aspect is quite amazing, and it's far and away more 3D feeling than any other I've heard. 
 
Overall, these aspects combine to give an earphone which is a marvel of sonic richness and scale. I absolutely love late night listening sessions with these, and I think it'll take a huge leap in earphone tech to overtake them. 
 
Recently I picked up an ALO silver cable for them second-hand, and am glad I did. To my ears it seems to open up the space a bit more even, and offer a touch more clarity. Very nice addition to the sound....
 
 
 

 

This Sony X has been my mainstay DAP for a solid year and a half. That alone should speak to its staying power. Prior to this unit, I'd been through DAP after DAP trying to find the one for best audio quality. Now I have found it. Even the much touted AMP3, being the supposed 'audiophile' player, was not on the same level. It is not perfect though, possessing a nearly worthless web browser- but hey, if someone is looking at this player it's most likely not because they want one which can surf the web, it's about audio quality!
 
Some of the sonic traits of the X:
 
- nicely extended and impactful bass
- highly detailed yet mellow treble presentation
- nice 3D quality to the soundstage (even if not quite as ultimately wide as the likes of a Cowon S9)
- well placed and detailed mids, not too far forward nor too far recessed
 
If anyone is looking for one of the best sounding players on the market, they should definitely consider the Sony X Walkman. 

I can't add much to the above reviews. They are some amazing universals. I can't understand any comments that the treble is lacking. To me, that comes from the 'trebleheads' who think the end all be all of audio is just how much extension we can eek out of the top end. Puh-leeze. There is so much more to these earphones, from the wonderfully tight and deep bass, to the natural clean mids, to the awesome detail and layering to their particular top end while remaining so supremely smooth without any hint of harshness or sibilance. The result is such a level of cohesive sound that it's addicting. 
 
Get 'em. 
 
But be sure to have access to some extra brands of tips beyond what is included, and do some experimentation. It pays off huge dividends.

This little beast of an amp is great. The sound is very neutral, yet full of power. The ability to adjust bass boost, gain, impedance, and crossfeed make it an excellent amp to use with any DAP, including iPod stuff (with their lack of user EQ). Mids are wonderful on this amp, being nicely full, center stage, and very present. 
 
I can't think of a better option currently for a portable which is so versatile to be able to be used with any DAP. 
 
I'm looking forward to seeing what Robert is up to next.
