Jeff Rowlands Amp and Dac vs. VAC amp and DAC

Hello all! 
I am very happy so far with my new amp and I just found an add on Audiogon that I want to run by you for a preamp. I was going to wait, and still might, but when something comes along it is good to check it out. What do you think about this with the 625 S2? Good? Not good? Keep looking? Buy it? 

The ad says: A Sonic Masterpiece! -- Lamm LP2.1 Deluxe Phono Preamp -- One Demo Unit Available - Mint Condition, $6995 

No, that's for turntables, but you are moving in the right direction.

Generally speaking, when having digital based transistor system you don't want pure silver cables. They will give you speed and resolution but often not full bodied sound. In most cases well done copper or silver/copper alloy will be overall better. Even in my analogue based transistor system with warm sounding speakers I use both pure silver and alloy interconnects, silver speaker cables. It is not that simple. There are also cables made of copper/silver/gold alloys, and Echole even uses some palladium. Think of it as putting different sets of strings on an acoustic guitar, you tune and then fine tune.

To recap,
Mac with iTunes  > long usb cable > Aeris dac > AQ Wel > JR 625S > Wilson Sabrinas.
System doubles for TV audio with TV in between speakers.

A few points :-
1: CD ripping with iTunes - lossy or lossless compression - AIFF/ALAC or just MP3?
2. TV in between speakers - ? interference from EMR, RFI
- ? interference with soundstage
3. JR 625S - v. expensive amps, still on demo at home or fully paid for?
4. AQ Wel - ? forgotten
5. Now looking at preamp despite good sound direct from dac to amps which are not well burned in yet
6. Aeris dac and Wilson Sabrinas - bought or gifted? broken in? separate components that came without amps?
7. Devialet - expensive but...not working?

Very puzzling......

Not really puzzling. A little chaotic but it's controlled chaos.
