Tube rolling Atma-Sphere M-60

Posted by bigamphunter on December 28, 2016 at 09:53:38:

Recently did a full tube roll on my M-60's. Ken-rad 6sn7's and RCA 6as7g's.
Not a night and day difference, but everything is better. Lots more dynamics,
increased micro detail-better sense of presence. There used to be collapse
of sound stage on dynamic peaks-no more and clearer. Well worth the investment
I was lucky to find all
NOS tubes. System is bi-amped with ribbon tweaters
