Best 6550 NOS Power Tube for CJ Premier 11a?


If price were no object...and the only goals were tone and longevity:

GE 6550A ?
Tung-Sol 6550?
Sylvania 6550 A?

Can we refocus:

Want ti replace the Power Tubes in my CJ Premier 11a with NOS 6550. Don't want KT88, KT 90 or any other tube type. NOS 6550 only.
I am told the amp was originally voiced with GE 6550a. I have located those as well as various NOS Tung-Sol. Goals are more bass but "tuneful", NOT "Thump, thump", extended frequency but NOT fatiguing or over etched, and "magic midrange, more like EL 34, with longevity and reliability. I am presently using   Russian "Tung-sol 6550."
I'm ultimately going to replace the signal tubes as well:
V1 and v2 are 5751
V3 and v4 are 6FQ7.
Suggestions please from those who have actually heard tubes in this amp...and remember please don't suggest substituting a tube type.
Also any experience with:

Vintage Tube Srevices
and/or
HiFi Town

Thanks!
I'm looking for extended bass, magic midrange, delightful realistic and not overly etched treble and extraordinary lifespan and reliability...just a few things  ;)
