I would also like to try other Sabre chip implementations however for the moment there is only the TP Buffalo around for DIYers like me who don't feel confident about prototyping. It will be interesting to see if Acko's implementation will be available before the tweaker-friendly Buffalo32S V2.
I guess that the TP must be pretty close as they are not restocking the first version.

yeah these guys are just curious about anything in their space, they live under the house as well, and i'm not blameless either; I left a finished coffee on the bench as well because I was so tired I didnt take the precautions I would usually. so I guess one of them jumped up there to check it out and knocked it over or something. there was nothing to spill, its not water damage or anything; just some of the fine stranded copper tore and caused a short as one possibility; was a bit of a shambles when I found it. put it back tio how it was and it actually turned on and played briefly (though I dont know what it sounded like, didnt plug anything in for obvious reasons; only connected via optical to be safe) with the lock LED flickering, then it went out altogether and never woke up. I quickly turned it off and broke it down into its respective modules. the MUX is still perfectly functional and shows lock when fed any signal, the power supplies seem ok, but I dont have any way of testing them bar my DMM and nothing bar the MUX to test them under load. actually one placid is sagging under load, but that might be fixed by simply reflowing all the joints or adjusting the CCS. but the dac board is dead  assuming (hoping) the regs are fried and nothing much else. perhaps an opamp or 2 in the I/V section. so when I get a moment to trouble shoot it for a little more info i'll email them. the acko is only a matter of days/weeks away; it will beat the tweakers board to market without a doubt barring catastrophic failure. bits also about half the price with premium parts. but then I would expect the tweakers buffalo to be less due to no I/V section, well you would hope so.

nah look, its nothing like that; I havent even contacted them about it yet; was waiting till I had a spare minute; been really busy with work this last week and also dont know how to put it without it sounding like a dog ate my homework  dont know if you guys have that saying?? nah its just that there isnt a BOM for the dac board and as i'm making digikey and mouser orders in the next day or so, it would have been handy to be able to just pick out the regs, caps, R's and a few other bits and tack it onto the order for when I do have time to try to work out what needs doing. although the 1632 isnt available at ti for a few months. with any luck it wont be too pricey or difficult to fix. sux because I have only recently been able to spend enough time with it to get my head around the sound and regardless of its difficulties its still a very nice piece of kit in stock form. its just not as flexible or errrmmm tweakable or organic sounding as I would like; but I knew that going in. i'm enjoying having some input into the project though; or at least feeling like I do
