I didn't feel like the 1578s had closed in highs and I didn't notice any noise in the upper registers, just the crackling out of one tube. They definitely had more pronounced bass, perhaps that gives some the impression of "closed in highs"?
Shootout of Nos 6sn7 tubes
I will have shootout between TS BGRP, RCA vt231, KR vt231, Syl vt231, Raytheon vt 231 and "Bad boy" next weekend.
If I get MELZ 6N8S 6SN7 Metal Base next week, then I will also include it in shootout
RCA5691, Psavne Acme 300B, Psavne Acme 805 are also being used in Line Magnetic 508 amplifier.
Speaker will be Lansche 4.1 with plasma tweeter.
Digital source will be Dave and HMS fed by ripped CD stored in ssd drive of Cocktail audio x30.
I will play
Eva Cassidy's 'Autumn Leaves"
"Trinity Sessionn " by Cowboy Junkies
For classical orchestra, "Trittico" directed by Fennel.
"Still harry after all these years" will be for fusion jazz.
Any more suggestion gentlemen and ladies.
