I will play

Eva Cassidy's 'Autumn Leaves"

For classical orchestra, "Trittico" directed by Fennel.

"Still harry after all these years" will be for fusion jazz.

Any more suggestion gentlemen and ladies.

OP,  your amp uses one 6SL7 and two 6SN7s, yes? I believe the 6SN7 would be the phase inverters. Correct me if I'm wrong.
I assume you've tried rolling the 6SL7. What tube works for you in this position?

I used to use Mullard ECC35 for more than one year.

But about 3 weeks ago I switched to RCA 5691 red bass which give more details and deep bass than ECC35.

The RCA red bass must sound terrific in your system.

How would you compare Melz 1578 and Sylvania 6SN7W metal base?
I was going to purchase a pair of 6SN7 tubes for my Supratek Cortese preamp and was considering the Sylvania as the one till Melz discussion here.

I do not have  Sylvania 6SN7W metal base.

But who heard the tube mentioned it is little bit overhyped.

I have  Sylvania 6SN7W brown base which sounds lively with good details but not in same class as 1578.

If is better to choose 6sn7 tube based upon what you want to improve.


The advantage of 1578 is nice timber,  bass, decay and widest and deepest soundstage.

If you want to go for utmost  transparency and details, then you had better get Sylvania vt231.

If you want lush and warm sound, then go for RCA vt231 grey bottle.

Just my 2 cent
