Experience with AMR DP-777


Hi there, I'm fairly new to audiogon, but have been assembling high-end systems for about 15 years now. Recently bought an AMR DP-777 and swapped tubes and it killed my left channel the first time. I'm no stranger to swapping tubes (in DAC's and Preamps), so I was surprised this happened. I've read some other threads that this sort of stuff has been an issue with this DAC. Of course the DAC sounds, but I have two questions/points:

1) for those of you that have experience rolling tubes with this DAC, what is your procedure to make sure it does cause some any system failure with the unit?

2) second thing is I've sent the unit in for the SE upgrade and will be able to report back to you guys the difference/improvement in sound, as I know it's sonic signature very well

I put the AMR on an anti-static mat and wore the wristband in a marble floored kitchen during the swap. Was swapping in the Siemen Cca Grey Shields :)

I'm still waiting for the SE. Sent my unit in May for the SE still no word. Feeling pretty ripped off. My direct feedback about AMR marketing is that they are a bit shady...say one thing and don't deliver (and do this over-and-over) -that's shady in my book.

I wouldn't look into any secret intentions with AMR wanting us to buy the DSD, I think they're just slow and experimenting with building new caps and it's taking forever. And announcing and missing a new rollout date every 4-6 weeks is pretty amateur.
Jsch123,

I sympathize. I know what you are going through. I went through a lot with them. Yes, IMO, their marketing and customer service need a make-over. I don't think they are the most professional folks on the block.
Welcome! Jsch123-

have you contacted AMR about your query?
I have some additional info / help if you need it.
Send me a PM. Happy Listening!

I believe that there is something off in their service and commitment to their customers. I've become reticent to go the distant with them
