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!

@mulveling-  Mixing tube types in a circuit, to reinforce the positives of each, doesn’t ONLY apply to 6SN7s, but works in most any application.

My statement should have been that the Sylvania 6SN7 do no re-produce bass very well. They are fantastic at almost Everything else
I think you understood what I meant. Take techno music for example . Most of it has a lot a Bass. I also understand that a lot of tube amps are not heavy hitters in the Bass dept.
Some people may not notice it too much... ????
But below is the real problem with 6SN7s  IMO as well as Many other's opinions too 

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

This worries me a bit to hear, although I am no bass freak, I like tight bass, using a solid state power amp instead of tube power amp make any difference?
