Thanks for the replies everyone. I definitely do not want a system that becomes too analytical or bright. My system is pretty well-balanced now for my tastes; blending solid-state amplification with tubes in the pre-section has certainly helped, esp considering that ARC gear tends to be more neutral than warm for tube-gear.
My current listening space is on the smaller side of things and is pretty limited in terms of what I can do with treatments, but I will be moving later this year to a house with a dedicated listening room that will allow for proper set-up. I was also looking at the Watt Puppys with an eye on being able to better handle that larger, dedicated listening room.
A lot more to think about…Thanks for all the replies!
