My Kootenay 120 arrived today. It has WE KT88 Plus with CV181s up front. I've had the preamp for a few weeks now. It has WE 6SN7s. It's nice to finally have both the preamp and the amp in my system.
Early impressions are very favorable, to say the least. An incredible blend of power, finesse, and musicality, with perhaps the most holographic presentation I've ever heard. The music is just enveloping. It's like you're swimming in it. The effect is mesmerizing.
I'll spend some time letting it settle in before doing much futzing around, but eventually I probably will try some different 6SN7 tubes just to see what that does. I've had a lot of fun rolling that tube in other amps and preamps over the years.
Looking forward to a lot of late nights coming up!
