I went down this path earlier this year when I upgraded my digital frontend to Naim's Reference ND555 DAC/Streamer. I initially bought it with one 555DR PS power supply, but purchased a second power supply shortly thereafter. One power supply for the digital side and one for the analogue. To put it as the Brit's say; it's a wonderful sounding piece of kit. Yes, the rest of my system is on par with this, and yes my private listening room is set up accordingly. Some will criticize that I have a TV on the wall behind the equipment, but my wife and I are avid golfers and like to watch golf on mute while we listen to our music. I do understand that I am truly blessed to be able to afford such, and that I have a significant other who not only goes along with my hobbies, but enjoys them along side me. I know that I am in the minority of people who can do such.
