Any opinions on the AMR Digital Processor 777 Dac?

Abruce,
I haven't swapped in any new tubes yet. I am waiting till my DP-777 is fully broken in. I am at about 380 hours. In another 120 hours, once everything opens up, I will have a good basis for comparison when I start to swap.

Audiofun,
I have emailed AMR about this but I don't expect a reply before next week. Perhaps you have some experience here.

I am currently using the R1 input on my DP-777 with a 110-ohm XLR cable. I am using the PWT PerfectWave transport. Although I can step-down the volume I have to use the volume control on my integrated amplifier to reach a maximum level of volume from which to step down using the DP-777 remote. I am getting the Atma-Sphere S-30 tube power amplifier to replace my integrated amplifier. Will I be able to use the volume control on the DP-777 using the R1 input?

Audiofun,
I received a lightning fast reply from Vince at AMR today, Saturday. I am apparently in the clear.

As usual, AMR delivers exemplary customer service. Theirs is among the best I have experienced in the world of high end audio -- which matches the quality of their products in my system.

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.

Sabai, sorry I am just now looking at this. I get busy with work and actually listening to music LOL and I sometime disappear off the forum for a while. I had my DP 777 upgraded to Deulend VSF Black Cast Caps on the output. Very expensive and very much worth it.
