The ADs with Lyr2 using Siemens Cca tubes, listening to Giorgio by Moroder ----> bliss .
Truly a 3D soundstage. You feel like you are in the cafe with Giorgio.
I bought the tubes from Upscale Audio. The tubes are platinum graded.
The one negative of this tube is the weak bass. But the 3D soundstage more than makes up for that.
This is what ADs are for!
Very interesting, I am looking for tubes for my lyr. Very expensive tubes though....
