For those looking for a nice TA2022 amp, the Topping TP60 seems to be a viable and less costly (at least where I live) alternative to the HLLY 90. After over 100 hours of burn in, the sound has become quite impressive, as opposed to just "great value for the money". I'm still not sure whether it sounds like a good valve amp, but it certainly has some qualities of one, such as spaciousness and good midrange.

Here's a picture of its innards:


I've been thinking about upgrading the already-decent components to something fancier, as well as removing the volume control after getting my Volumite. Open to opinions and advices!

Again, big thanks to Ali and John for recommending the HLLY 90. I would've never taken T-AMPs seriously if not for them!
