I would second the thought to try the 11A in the main rig. I love moving stuff around to hear the differences. Right now the 62SE is with a 17LS2. There's an Conrad Johnson age gap, but they are possibly the best partners in the house. They are paired with Dynaudio Heritage Specials in an upstairs room.
The Vandersteens downstairs are being fed by a Herron 360 > Herron M1s. The Herrons seem to have a wider range of low volumes available than the CJ pair.
There's plenty of threads here lately about which preamp for under $XYZ. My latest adventure is checking out a refurbished Threshold FET10 HL. I remember an old article about reviewers at the same magazine in the late 80s fighting over it. It was reportedly essential for their reviews of other equipment.
The Conrad Johnson Premier 11A is a true work of audio art and history. I'd love to hear one, and I admit to alerts through Hifishark.
