If I hadn't just done it, I probably wouldn't have believed such an improvement was possible with just a few little (but expensive :-)) tubes...

Fplanner2010, Your 300.1 weren't broken ... you said if best yourself :-) I'm also a big fan of the BT CV-181-Z and rolling them in my DAC so imagine rolling a super CV-181-Z in your preamp. Tube rolling is just a vehicle that is available for an user to dial in the sound to their taste ... no right or wrong and bad or good but just personal preferences.
One of the reasons I decided on a VAC was it ONLY uses a MP of 12au7 and e88cc. These are very common tubes that I'm familiar with so it took little time in dialing in my sound.
Dev, funny your ask. One of my long time tube dealers found me a new MP of 60's Siemens CCa and just got them last Wed. But the system is sounding so good, I don't plan to tinker with it for a while. I finally settled with 60's Siemens wide getter support post E88CC and 50's Telefunken ribbed plate 12AU7 / ECC82
I agree with everyone just enjoy your 450 Statements and Preamp in stock form for a long long while. A Ferrari is a Ferrari whether it's riding on Pirellis or Michelins :-)
