I replaced the default tube in the Vali2 with a Telefunken Black Diamond from Tube Depot and even with this cheap headphone amp ($150) and Fiil headphones the improvement is very noticeable sounding smoother and more musical - more relaxing to listen to.
Does anyone know who makes the $10 tubes that Schiit uses?
