I really doubt you will hear the difference between a solid-state preamp/power amp setup and the Valhalla 2. That's mostly for guitarists (me!) where you want some preamp distortion or preferably power-amp distortion at reasonable levels (not like a Marshall stack going full-bleed). So I personally like my Valhalla2, it works well with Sennheiser hd600 cans, but really not much better than much cheaper and now discontinued Magni solid state amp. For hifi purposes I think solid-state has to be as good as tubes. There is no such thing as 'tube magic', that's just a figment of your imagination. But anyway, your experience may vary, maybe you get something better out of your headphones/speakers. I love tubes as a guitarist, but honestly, the value-added in hifi systems is so marginal, can't really see it. After all we're not trying to achieve a smooth distortion or overdrive! Which is what guitarists are after. So if your current system is solid-state, or hybrid, and it works, stick with it. Going to the Valhalla2 will not add anything apart from expense. Also, be aware the Valhalla 2 is not great with low impedance cans or iem's as is otl amplifier. I would stick with the Vali2 if I were you, more flexible as regards cans and iems. It sounds great with Sennheiser hd600 and other high-impedance cans, but otherwise meh. Works with iem's and low impedance cans, but not very well. Well ok. Can't hear the difference betweem Valhalla2 and Magni+.
