The Amps I Tested
The [Schiit Valhalla 2 OTL Tube Headphone Amp](https://www.amazon.com/s?k=Schiit+Valhalla+2+OTL+Tube+Headphone+Amp&tag=thetestedhub-20) is my overall pick. The OTL design pairs perfectly with high-impedance dynamic headphones and the noise floor is the lowest of the group.

Questions answered
The tubes themselves do, but a quality tube amp will run thousands of hours before needing tube replacement. The chassis and circuitry often outlast solid-state designs.
Only on amps with sockets and a tube type that has multiple variants in production. The amps I picked all support tube rolling, which is a big part of the fun.
