Any opinions on the AMR Digital Processor 777 Dac?

I am wondering what users are thinking of this dac and if they have compared it to similarly priced units. I haven't seen much information or any professional reviews at this point and I am intrigued by it's functionality.

I enjoyed the DP-777 for a while but swapped it for the NAD M51. No looking back.

I'd make sure to listen to it before buying to my ears and in my system I didn't like it

I am considering buying an AMR 777 DAC. Have any of you guys tried the Berkeley Alpha USB feeding the AMR 777? Do you think it will sound better using a Berkeley feeding a BNC input? What is the ifi iUSBPower unit? Does it require 2 USB cables? I have an Audioquest Diamond USB cable is it a good match with the AMR?
I want to test this unit with the best possible setting.

Coxhaus, USB/SPDIF converters do make a difference, I am using Yulong U-18 with great result after trying a bunch (including Off-ramp4 with all options). The iUSB Power works on passive converters but has minimum impact on Yulong, which already have a robust active power supply. You do need two USB cables with the iUSB, I found USB cables make a small difference (don't use stock computer cable though), but coaxial digital cable makes a big difference.

I have my AMR 777 in house and I am breaking it in. I only have a little over 50 hours now but it is running around the clock. I have come across an issue and maybe someone can help. The first day the DAC ran with my Berkeley Alpha USB connected using BNC with a Purist Dominus Digital cable. The HD DAC chip running organic mode sounds nice and organic. The Philips DAC chip sounds kind of closed in with a small sound stage. If I switch to USB straight into the AMR 777 the Philips chip sounds better to me with a larger sound stage. With direct USB the HD organic chip mode sounds a little to clean to me. My problem is I want Redbook to be directly connected to USB but I want HD to run through the BNC connector. I cannot have both as the Berkeley computer drivers and the AMR drivers cannot be installed at the same time and trying to switch is not practical. Why would the BNC input be different for the 2 DACs? Can anybody confirm what I am hearing?

What are you guys doing? Any ideas?
