I've found the quality is pretty fair/good/excellent on a lot of the 'Tube stuff. Your's, for example, is very good to excellent. I give 'em a pass if it's not up to my very high standards! I have been a highly practiced audiophile all my life........can't see without my glasses, can't run down the badguys like back in the day, and other assorted old fart stuff.......but I still have exceptional hearing and and am particular to the point of anal about my music quality.
Thanx for the offer but the snipper I have is very good and I have a bud that set me up with a quality thingie for audio files that cleans and enhances. Sort of like a DBX 3BX spectrum analyzer/enhancer. (Lawdy! I just dated myself even further!)
Anyhoo, thanx again! Day off today and yesterday sucked so I gotta retire to the lower level for some 'concert therapy'.

Can't wait to hear your two pieces the way they're meant to be enjoyed........7 speakers at a lot of watts! 8-)
