I agree with mboldda1
The Ultraverve never fails to amaze me. I use mine with a vintage 5692 6sn7 military tube. It also sounds great with the usual suspects: Tung sol round plate GT, Raytheon vt-231, Sylvania W, Kara, the designer of the Ultraverve is very responsive to questions, upgrades, etc. She recently upgraded mine with Dueland caps. I run it through my Bryston 14bsst. Highly recommended!
