Thanks Unsound, your thinking makes sense to me.
Re bright Thiels, it was the one thing I didn't like when I first got my 2.3s, but it can be tamed. For me it meant that each and every upgrade/improvement had address this, and room treatment amd arrangement (rack to the side wall), careful speaker placement (including height), speaker cables (AZ Holograph, thanks Eric Squires!), and Isoacoustic GAIAs all helped in different ways, the clincher was upgrading the digital source (went with bel canto 3.7). All the while I was rolling tubes, and one thing I have learned to appreciate is being able to hear most (not all) of these little changes. One reason I went for Thiels in the first place as a newbie audiophile was bc of their reputation to be very revealing of the signal, as TT mentions above. I knew I'd be cycling through equipment cables etc and wanted good chances to be able to hear the differences. Thiels have delivered!
