Any opinions on the AMR Digital Processor 777 Dac?

The DP-777 is here, used with an optimized HP touchscreen music server.

If you are in the Chicago area you can come for a demo or request an in-home audition. The CD-77.1 and CD-777 also are on display.

Authorized AMR dealer.

Yingtonggao, try J River Media Center. It costs $50 but is well worth it. The other thing you want to do is disable kmixer in XP or upgrade to Windows 7 if possible.

Running JRMC on Win 7 here, optimized, into the DP-777, with superb results.

Cmalak: In the last paragraph of JA's comments he mentions sending a 24-bit/44.1kHz signal to the DP-777, and since 'Auto Select' was enabled it saw the 44.1 sampling rate and selected the 16-bit Classic DAC, this is why it downsampled (truncated) the 24-bit signal to 16-bit. He could have either turned off auto or manually selected the HD DAC.

There are not many 24/44.1 music files out there, so one might wonder why he chose such a signal to test. Surely 88.2 or higher would have made more sense.

F1a: No.

Yes.

Sabai, Vince of AMR emailed me this morning asking about it, and I immediately replied that it works fine into the MA-1s here, which enabled him to quickly respond.

Good luck and listening.
