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.

Looking forward to your findings. I've tried TS BGRP, RCA vt231, KR vt231, Syl vt231, and various Sylvanias.

I'd like to hear a real Meltz Metal Base in my system.



How about adding "The Unknown Soldier" from Weather Report's I Sing The Body Electric! I have used this as a test track for decades! The rest of the recording is also outstanding!
I will add "Thriller" to test soundstage depth and width , dynamics.

It will be nice if I can get Melz metal bass this week.

I ordered it 3 weeks ago.

I bought this as reserve 6sn7 for Freya which use quad 6sn7.

After using KR vt231, I switched to this pair. It sounds clean and transparent with nice decays.

It sound better than " Bad boy" which cost me 10 times more.

I will also include this one in shootout.

Sometimes you can find nice bargain. But it could be hit or miss.
Agree with Iwin on the Sylvania metal base 6sn7w’s.  Most of the others are splitting hairs, but these are a clear step up.
