Tube rolling in the Cary SLI-80 Signature
Interested in hearing about your experience with rolling tubes in the Cary SLI-80 Signature -- different new-manufacture and NOS -- especially at it relates to Merlin TSM-MMI monitors. Also, tube rolling in the Ars Sonum Filarmonia. Are NOS a marked or marginal improvement, and if so, how so?
