Small or big tubes/valves for pre amp ?


Hi guys, have been thinking about going to a tube pre with a solid state amp.

I have a hybrid intergraded amp with small tubes in pre section, I am no expert in tubes, but know my way around the 6DJ8 / 6922 / ECC88 variants where I have preferred the Mullard tubes with my amp.

The pre amp that I have my eye on is the Don Sachs model 2, it uses bigger tubes and I am told that the bigger tubes have better sound than the 6922 variants I am used too.

Would appreciate if someone could enlighten me about the difference in sound signature between these tubes, I believe that Don uses 6SN7 tubes. http://www.dsachsconsulting.com/custom%20line%20stage.html

Thanks!

I'll take 6922 based gear all day over 6sn7. Not a fan of the 6sn7; they all have their own sonic quirks and colorations which is why you get recommendations to balance 2 types off each other. And if you have a high-gain circuit you'll likely run into noise/microphonics issues unless you go for the later GTA/GTB versions, which also aren't as sweet sounding. The only one I really liked sonically was Tung-Sol black glass round plate VT-231, but they're so hard to source with any decent life left - and again, good luck with noise.
