Speaking of bargain gear, my original series Schiit Freya preamp (there are two newer versions, one without tubes and a supposed improved version of the tubed one) sounds excellent, as does the Schiit Aegir amp I just bought out of curiosity (I generally use a Dennis Had tube amp...also relatively inexpensive)...total for those two was around 1,600 bucks, USA made, and the Aegir is by far the least expensive amp to make the Stereophile Class A recommended stuff list. Note the Aegir needs either efficient speakers (mine are rated at 99db) or use two in balanced mono. I agree with Atmasphere that tone controls are rarely needed if your rig is well sorted, but a Schiit Loki (too much Schiit? maybe...still another very inexpensive option) is by far the least harmful EQ I’ve ever used...utterly transparent (mine is always off until called into service), and useful here and there.
