I just found them on the bay. USA west coast supplier.
a good DAC to hear first would be the Beresford Caiman SEG £150 ex vat, which is approx $188 USD, use your own favorite Linear Power Supply 12 to 15V DC, they are hundreds of good reviews on google, Stan the owner is a great HiFi chap who wants nothing more than his clients to have a DAC competing out there with the more well known brands, I compared it with a Weiss DAC 202, the PS Audio ( all of them), some other DAC's in the the shop, I had my cheap Popcorn Hour A-500 Pro with me, we played 5 different DSD Stereo 2 Channel files and the Caiman was more than capable of holding its own, I was shocked how well it performed !
I think $1000 USD for a system that plays DSD64 files is achievable and will make a lot of people smile when they hear what can be achieved SQ wise for very little dinero, if good active speakers were available for around $500 USD then the world would be a better place :-)
Could you elaborate a bit? I'm just curious about that DAC myself and its attributes. Particularly what is better about as opposed to the iFi, which I was also looking at? If you don't mind.
