I'm not familiar with your Aerial speakers, but picking up on the 86dB spec. I never felt that I did my Thiel CS 3.6 speakers their justice due in trying to drive them with tubes, so also 86dB. They would have probably benefited from a fine 200w SS amp, for example.
Today, I have 300b mono blocks driving much more efficient speakers, and that's a happy mix. When I got the mono blocks I was stuck with an integrated tube amp without a preamp out. I dragged out my old Boulder L3AE line stage as a temporary solution. I had it recapped and it sounds great in my system. Someday, I'll upgrade to a fine tube line stage, but l'm not in any hurry. Just saying.
