Amp for my Quicksilver LS


I just picked up a QS preamp and need an amp for it. It's an older model with 12AX7 tubes and my speakers are Ascend Sierra 2s that are 84db efficient. My background and preference is tubes but I'm open to trying a SS. My budget is under $2K. Preferably well under. Thanks.

A few have reported QS Line stages mate well with Odyssey amps. $2k should get a good amplifier from a variety of manufacturers as well.
Thanks for the suggestions. Not sure I want to go with monos as I'm limited on space.

((((Not sure I want to go with monos as I’m limited on space.))) The 2 Preowned Quicksilver monos besides sounding incredible do not take up any more room on a single shelf than a stereo amp. Furthermore, if you did want to run them next to a speaker with long interconnects you could either way it works.  Also, the well-intended recommendation of Quicksilver pre with the very low input impedance Oddesy IME is borderline for best performance suggest an amp with a 100 K input impedance like a Quicksilver or ARC 100.2. Best JohnnyR
