@twoleftears Perhaps a different positioning for a different amp is called for — that’s why my question included "Or, perhaps, am I failing to do something -- such as re-position my speakers?" That said, I’ve done measurements regarding impulses (first reflection, distal reflection, further reflections) and I don’t see much of a measurement difference between them regarding the kinds of timing that contribute to sound stage. I suppose just moving the speakers around would be an easy experiment. Thanks for that idea!
@audioguy85 I did a lot of movement of my system and back wall distance proved very important, both for SPL and for imaging. My guess is that rooms are very different, and my 6.5 ft. ceilings are a factor which probably you (and Fremer) don’t share. Possible crucial difference.
@zlone Wow, that’s a very controlled experiment and interesting result. Yes, I use great test tracks and yes, I’m using a tube preamp in front of both amps. With NOS Valvo 12ATs in it.
@jjss49 I’ll look at the distortions discussion.
