Studio B has a warm tone. You cannot do anything about this. Part of it is the 300B. Part of it is the output transformers. I have a custom amp which uses the same output transformers but with x2 45 tubes in parallel per channel. It's only slightly less warm than the Studio B, but still bit slightly more warm than neutral. Still, the Studio B is less warm and rolled and rich than most other 300B amps because of the small amount of negative feedback from the tertiary windings. I would recommend the EML solid plates if you want a 300B that get a bit more "bite" from the Verite. I haven't heard any of the latest and greatest 300Bs that cost more than $1k. I'm done chasing the dragon.
