Definitely NOT first-class soldering, though... quite rough!

I think I will pick one up just to see how well it does with different Op amps Ive tried just about everyone possible so
this should be fun..
A lot of it is implementation, as with anything. Have you heard the amp in question? I know the XTRA X-1 was questioned on the basis of its opamps but I find it detailed and open with a bass that is fine for most music.

I agree. I think making snap judgements about an amp's sound based solely on the op-amp used makes no sense. It might give some idea, much as you can get some idea what an amp that uses EL84 tubes versus 6922s or 12AX7's will sound, but it gives only a hint, not the final answer.

It is nice that they have socketed the opamp used for this amp. Molding to taste is always fun. Again I will state though it is implementation and as Skylabe mentions, assumptions can be misleading. I used to dislike the 6DJ8 family with a vengence until I started working with the operating points. I now find it to be one of the most dynamic and enjoyable tubes to be used in a driver position, even preferring it to my much loved 6SN7 Black Glass Tung-sols and 1952 Sylvania 6SN7's. I will not say this about my 1929 Sylvania 27 balloon mesh plates that sit a top my preamp, as they can not be replaced if for nothing else than just looking beautiful. :^)

I have not heard the Ibasso and I agree that there could be and amp out there that sounds good with the op2134 I have never heard one. My point was there are better opamps out there and that with the ability for amp rolling will allow us to change to taste Im sure that it will roar with a better opamp
the 2134 is a cheap almost jellebean part.

Well it is nice that there is a socket in the iBasso, so hopefully the amp can please the picky ear of the audiophile. I have some AD823's coming as I needed some anyway but I will give a good listen to the stock unit. My SM LE has many hours on it now and for me is a bench mark of transparency, openess and neutral frequency balance.

Yeah I think that the 823 or maybe even an 845 will surely bring the unit to a more realistic soundstage the 823 chip has
somewhat of a holographic sound because it is self buffered
will be interesting now for me to get that Ibasso wonder what he is accepting for offers
I really should do a follow up review on chips I have been op rolling in the Xm4 and have not tried almost every plausible possiblity I was very dissapointed in the LM4562
I thought this new chip would dethrown the 823 also I have tested the 627's with the burr brown adapter and even though the sound is the best of all the Burr brown chips there is still an unnatureal distorting especially for rock music I have the 8604 AD coming in SOIC that I will solder to a pdip adapter and the 845 after that I will write up an extensive review of all op amps that were left out of the tangensoft review site.

I am lost right now. The Xm4? Maybe it is too early in the moring for me.

Maybe the 8620 would be a nice try also.

Have you seen the iBassoT1 that just showed-up on eBay? An interesting form-factor, but no specs are listed for size, gain, opamps, etc:
http://cgi.ebay.com/iBassoT1-portabl...QQcmdZViewItem

I still don't understand sellers who fail to put some sort of common object (credit card, ipod video, etc) in the picture so you can tell how big the amp is. These things are intended to be portable, it would be nice to know how big they are!

I saw that - looks really cool! Very cheap, so I am going to get one. I will report back.

Ok Skylab, now you're just out of control!

That little unit is very interesting, good competition to the Minibox possibly, and at half the price. Looking forward to your further comments

It looks styled after the Ipod. I will have one in about 7 days. I like the images. It has the Max chip, one for each output as the amp can run two headphones at once using two different opamps and runs around 39 hours on one charge. It should be interesting.

Max huh? Then its running head on against two of the three Minibox offerings. I'm not crazy about the Max sound, but it seems to be the way to go if you want a truly tiny size and great battery life.

The sheer amount of amps on the market now is amazing!

may I ask where you found this info? can you provide a link to it?

indeed it would look really nice as the backing looks very mirror like, just like ipod , but the size hummm how big? how small? I agree with other comment about a reference item in the pics.

my GUESS is that its the exact "standard' ipod width and length. just a guess, why else would they give it that mirror case?

EDIThere is a bit more info . when asked at ebay where this product the Ti falls in the iBasso line to the P1
