Shootout of Nos 6sn7 tubes

I paid 575$ to get TS bgrp.

I could get four pairs of each RCA, KR, RT, Syl vt 231 at total of 500$.

It is much better to have four of kind with  different flavor than over hyped TS bgrp.

Thanks for posting your results. I’ll start by saying all systems are different. I agree with your results of the KR VT-231, RCA 231. Also the Sylvania VT-231; very good tube but bass is light and not extended.

RCA vt231 is kind of all around player. Compared with TS bgrp, its sound is slightly warmer with lush tone but with enough sparkle and air.

Good description, I find the RCA to have great warmth and air. For a more neutral tube, RCA GTB has the same mids and great top-end.

However, I must say the Tung-Sol BGRP is my favorite tube. I find it to have smooth extended highs, transparency, and solid bass. A very musical tube which presents  realistic sonics.
I paid close to $500/pair. Very expensive, it’s become difficult to find matched pairs with low noise and microphonics. Some of the Sylvanias would be a good substitute and they are very affordable.

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.
