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.

I did a shootout years ago with many of those tubes .....IMO the KenRad VT231 appealed to me the most.Lots of natural tone, body and detail.

I like Kenrad too.

But RCA seems to give more sparkle and air than KR.

Let us see what happen.

Like tuberist I tried a lot of 6sn7 tubes. My favorites were the metal based Sylvania’s stamped USN. I now use 6f8g and BL 63 tubes instead of the 6sn7’s because I like the sound a little better and the old 6f8g tubes from the 40’s are a lot cheaper then the 6sn7 of the same vintage. With easily obtainable adapters they are drop in replacements for the 6sn7. My favorites are the BL 63 tubes but you have to be careful using them as they require a little more current and might cause problems to some gear. As always shkong78 I look forward to reading about your findings.
