I treated myself to an Abass hybrid SS / tube I/V. Now I just need to get the BOM ordered....

Hello all music friends, i have some news... today i connected the jdlsoundsviii in simultaneous mode config to the d3distinction. It worked from the first play. The sound is very good, i donīt know if are the ndk clocks, if is the way the reclock is done but in my previous experiences with akm dacs i also preferred this board against Ians fifopi with crystek clocks and lipo ps. i did not compared to ian fifopi with the is2tosim since i could not run ok... i have to put ndk clocks in fifopi i have to check the i2stosim board again to make the final judges,...
It works ok with upsampling till 352800 hz
I m using foobar on a laptop...nothing exotic...

Ryan, so, I can use the non A, its just that the Dem won't get reclocked, correct?

Thanks,

Greg

Hi Greg,

It should work but I wouldn't recommend it. But if its all you have then you could use it until you find another one. There is a sound improvement lowering the DEM to 50Hz.

Yeah, it's all I have. I'm trying to get the right used cd player with an S1.

Good idea, less chance of it being a fake but cd-players that have an S1 are getting harder to find.
