I'm looking to enter the world of tube amplifiers. I had settled on buying a used Valhalla 2, but now that I have found one to buy, I'm wanting some confirmation. I've read here, that the Valhalla 2 sounds solid state-ish. I really want to experience tube sound, and plankton. Together. I've owned an OG Vali2 and am not opposed to the new version, except I'm not a huge fan of the Magni 3+, and it sounds like the Vali 2+ is a marriage between the Vali 2 and the Magni 3+. I never tired anything but the stock tube though. I feel like the Vali 2+ would be too much of a side-grade. Opinions on the Valhalla 2 as well as other similarly priced options would really be appreciated. Headphones: Grado PS500, Sennheiser HD58X Dac: Modi Multibit (work and home) Transport: I have 2 raspberry pi's with HiFiBerry Digis (work and home) Current Amp: Magni 3+, and a DIY chip amp I sort of hacked together because I get bored and am curious by nature. EDIT: I also built a Schiit coaster amp, and I enjoy it, but I'm interested in a better amplifier. I'm open to acquiring an HD6XX as I really want to hear what these can do on a tube amp. (If the HD58X isn't close enough with it's lower impedance). Also, I live in Arkansas, and I don't think we have any way to audition things near. Closest would probably be Dallas or St Louis or possibly Memphis.
