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,
