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"

For classical orchestra, "Trittico" directed by Fennel.

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

Any more suggestion gentlemen and ladies.

Thanks for your kind word.

Overall TS bgrp is the best tube but law of diminishing return apply too heavy here.

I have 6 more sets of 6sn7 Nos tubes for shootout including Melz 1578 metal base coming from Ukraina.

Yes, I understand you saying law of diminishing returns. Looking forward to your thoughts on Melz. I'm looking for a pair of input tubes for my Atma-sphere amp. Right now I'm using 6 Sylvanias.

shkong78, Thanks for giving us the results of your shoot out.  It's a lot of work to gather and listen to all those tubes in your system.

Aside from which tubes are among the best, I take away a couple of points.  First, the law of diminishing returns applies big time in audio.  you're going to pay a hefty premium to get something that is considered "the best".  

Second,  There is no one best for everyone.  Our ears, systems, and rooms are all different.  The tube that sounds right in one person's system may not sound right in another's.  If you're looking for the best tube in your system, you have to try them out yourself.

Thanks again for the info.

Bass too tight?

Of this group I think the Tung Sols are the best. With probably the Raytheon as my 2nd choice. Ken Rads are usually very problematic in high sensitivity applications. K.R.s probably my least favorite. The GTBs tubes from the 1960s are actually very good and are very reasonably priced. Best of these would probably be the Tung-Sols or maybe Sylvanias.
