200€...sounds anemic...forest of lousy opamps in filtration/analog section are to blame. Will be modified with only 4 double opamps...2 for external I/V conversion, 2 for fully balanced ground reference 2nd order output filter.
Price doesn't matter if it's the right DAC
What about price for upgrading ? Are you able to do the mods yourself ?
I am only able to get the coaxial input workable ...not the USB. Do you know how to ? There is a jumper included, but it seems this jumper is ported to the optical input. I've tried to connect it to all holes, without success.
Maybe there should be use of a driver ...i'm using Linux Mint 13 as OS.

Seems like a good start = the analogue
There must be some good one out there instead of 5532, 2134, 2132 ...what about 627 does they fit in ?
I would contact a seller first about USB not working.
Well, 627 is a single opamp, obsolete and expensive...you should be reading ADA4627/4637 datasheet instead...than tell me what you see, he, he, he 🙂

correct about the 627 but 4627 is also a single
instead there is ad8512, ad8620, ad8652 and ad8616 dual ...showed in this list.
ADA4627-1 pdf, ADA4627-1 description, ADA4627-1 datasheets, ADA4627-1 view ::: ALLDATASHEET :::
yep, i will contact the seller ...and it seems i'm lucky, they are writing about them self:
It is handmade work, not something produced by factory, we also are diy hifier, not just only reseller like others. we have many other
finished DAC、amplifier， preamplifier ,headphone amplifier，tube amplifier and other hifi DIY audio parts for sell.
please add my store to your favorites.Thanks.

Yes, but if you (whatever the reason) want to use 627 somewhere, you want to compare datasheets for 627 and 4627 first😉
I'll take a look at 8510...you can take a look at AD8610/8620.
I run through the datasheets...i think you/me should stick to AD8620 as a prime candidate for the moment, especially as I have already heard them in TDA1547 dac (really excelent sound, btw).
I do agree ...it seems the best one.
Buuuut i'm interested in some quality ones. After the last three times buying ic's and semiconducters from China i haven't been lucky ( got several fake ones ). Should we go for Mouser or RS for good safe components ?
This days one should buy from reputable source only...to many (all?) fakes around. Also, you should check if you can get free samples from TI/AD/LT/etc. Unfortunately, AD does't supply free samples for Croatia...'cos I really like their opamps (e.g. AD744 + AD815 killer combo), what a shame!
Free samples i've never heard of that. A shame that Croatia is not included for that deal.
What about this one ...is it outdated ? opa2604 !

Only in testing phase (opamp rolling), once you make up your mind, solder them directly on pcb, even if you need to bent/stretch legs a bit (proper decoupling is the major thing to look at)
okay nice to know ...what capacity of decoupling caps are you using, for these ?
it seems easy with these conversion kits

OPA2604 you say...interesting opamp with simple distortion correction buit-in...good in it's days, but surpassed by new opamps I think (you have to buy it, TI does not supply OPA604/2604 samples, do not understand why, as you can have any other but not this one)
As I already mentioned, the adapters can be used only in the test phase, you can only dream of proper decoupling with them. For decoupling I'm using non-inductive film (= or <100nF) + 47-100uF electrolitics (low ESL, low ESR, high ripple current, the taller they are and smaller diameter they have, the better)
