Grannyring,
Thanks for the thorough review, and I appreciate the fact that you’re able to provide this in the context of the extensive list of amps you’ve owned. After reading this, and spending a significant amount of time on the phone with Peter McAlister, I’ve placed an order for the PP150S.
I’m also driving Dali’s, though mine are the Grand Diva rather than the Grand. If you get the monoblock SETs, I would be interested in hearing your opinion on how well they manage the Grands. I had considered going that route also, but Peter felt that I’d be better off with the PP150S considering that the Dali specifies a minimum of 50 watts into their 4-ohm load Grand Divas.
Also wanted to add, the bias pots are on top as a standard feature now.
Thanks again.
