Note that he first had it set for the wrong load for his cartridge.

Frank,

After I phoned you for instructions I did change my new Phono Pre to the 20 ohm load.  But noticed a harshness and brittleness in the high end. 

Moments ago I got my AT OC9 manual out again and read the hook up notes, instead of just the specs. It said 20 ohms for a Transformer, and 100 ohms for a head amp.  So I reset it to how you set it up at your house and instantly the harshness & brittleness disappeared. The Music is so much more alive and the image is now more specific, deeper, and not at all confined to my speaker dimensions.  It is also a bit louder with a quiter background.  Since I got home I've been playing & loving albums I haven't listened to for perhaps 25-30 years. I am happy and excited! Sorry I didn't read the instructions closer several albums ago. BTW my wife noticed right away even at 20 ohms how much better this sounded than the Parasound.   And it isn't even particularly warmed up or broken in yet.  Gonna be a fun cruise.  Thank you,  Mark.

I'm listening to music every day now, mostly on vinyl,
with my new Fet Valve RB preamplifier and its Vision
Phono Section. Fantastic!
