SS Amp for Avalons

Although I've owned Avalon/Spectral and heard it many times at dealer, I preferred Avalons with BAT tube monoblocks or Atma-Sphere monoblocks. The BATs had more bottom end power but the MA2s had a great mids & treble particularly on acoustic instruments and classical music. If you are a rocker, BAT might be a best choice. If SS, I agree that Symphonic Line and Pass are some of the best options. Cheers,

Aren't Ayre & VAC both made in USA? 

It's true that Avalons are revealing & everything matters. Compared to many other speakers some might call them overly detailed or etched, especially when matched with ss electronics. My ownership experience with them was short because that combination left me fatigued and drew me away from the music not towards it. All the engaging Avalon experiences I've had since have all been with a variety of tube amps.
Don't let a short dealer demo with ss electronics, backed by rave magazine reviews be the only listening you do before going that route. Learn from my mistake. Cheers,
Spencer
