Yes, I have the same concern and as the expression goes; I'm fishing in deep water. I'm planning on moving some amps around. I have a Yamaha M80 on my 250ti's that I will move to the ARs due to less power and the M80 has individual gains. Though it didn't do well on the 9's initially, I'm hopping that in a bi-amp config it will provide better performance but at the same time provide a better chance at balance. I will find out soon enough. Thanks for the feedback, I was beginning to hear crickets. The thread before yours recommended the a good site, one I'm a member of but, it just slipped my mind, I have been so focused the SET lately. Some feedback on tubes on the 90s but, nothing yet on the 9's. Thanks again.
For those familiar with the original AR9 and tubes
I'm considering (it's actually on the way) driving them with an SET 845 tube amp at 18-22 wpc. Currently running Adcom 565 monos; incredible bottom end, too much in fact. Mids and highs very clear but shrill. Hard for me to articulate the impression. Listening fatigue sometimes but, not always, seems to depend on the source. Room is 3024 cu. ft. with an open side of the long axis. Less than average reflection. My expectation is that I will bi-amp with a ss on the bottom end and eventually change to a tube application. Thoughts, considerations, and for those who really know, any recommendations?
