Hello again.

Thanks for your response. I appreciate it, it's not so common to very knowledgable people being nice with the newbies, thanks.

I send an email to the ebay seller (diyinhk) of the XMOS USB to I2S to ask if I can buy one of those,
until now I didn't get an answer and I now see a new item from him, but I pressume that is not
exactly what I'm looking for:

http://www.ebay.com/itm/XMOS-1…..d=ViewItem

because as I understand this is an XMOS USB 2 SPDIF, but it didn't have (at least I can't see it) the I2S port,
so I can't pair with the Sabre 9023 that I already bought (yesterday
worst of things is that the cost is USD 30 more, and I didn't need the case and it didn't have the i2s. shoot.
I think that I will wait then.
(This is an option ? http://www.ebay.com/itm/LJM-Au…..19dde66b0c or there are better options ? )

I have to think a little more about the AMP section, those 125ASX2 looks great (for the specs I mean) but
my pockets are not so full at this moment.

And yes my loudspeakers are 8 Ohms, could be Bi-Amped or Bi-Wired and are pretty efficient (97db/W/m).

Again, thanks.

Well, an update.

Today Mr. diyinhk contacted me and told me that they have a small qty of the item I need, so I
buyed it, directly, I hope the component be send, being an operation outside of ebay is not that good,
but if other members have buyed and it had more than 1100 transactions I think everything it's gona be allright.

I keep the "research" on the amplifier part, an idea could be one ICE Power 50ASX2 now and a second in some future seem a nice combo
(to my pockets, to a sound test, and finally power). But as usual, in this research I keep crashing with Tripaths and
Mauro Penasa's MyRef RevC (LM3886 based but not in a GC config), thing is, I already have about 6 x LM3886
and a handfull of ultra fast MUR860 diodes. I will keep thinking, anyway now I'm waiting for my receiber and DAC

You recently introduced a new component (oh, no, not more, please, ) you mention the pre-amp.

In my current setup (the AMP6 from 41hz with a TA2020) uses an attenuator and a relay selector (for input channels), I designed and fabricated all these,
with a home build PCB, I used (and programmed) a PIC 16F628 (IIRC), I used to read Elliot Sound Products a lot, so I learned some good practices, there is no audible sound at MAX power comming out of my speakers with the inputs open. The PIC commands a pair of MCP41010 (i2c digital pot ICs) this are not audio specific but works ok (some minor noise on vol.change, I later discover a similar part from BurrBrown that have a Zero Crossing detection to solve this problem).
Finnaly, I programmed the PIC to learn RC5 remote control commands (from a Phillips TV we had) I'm lazy, so the physical pot was a choice for a brief period of time. And added a very small EI trafo, that way, the PIC is always ON, but the AMP swiched (mute command on TA2020) so, probably it only consumes less than 5 watts in standby mode. (I measued it, to confirm the low power use, but I can recall now what was the correct power usage)

But, you talked about a good preamp, I'm on DIY, I like it a lot, BUT, I think that my country policies on imports (customs) isn't ready for valves, neither do I (I don't know anything about it). I have some 5532 and OPA2134 lying aroud, I made a very nice sounding OPA2134 CMOY. So there are some good recomendations on a pre-amp for my receiver/dac ? I know that until I don't have the AMP is probably futile to recommend something, but just to keep on the research. Elliot Sound Products have some proyects, but again, I don't know what is the most valuable characteristic to look for.

Then again, thanks, Diego.
