Hi @mrdseitzer , I have audiovectors (among others) and have listened to most of the other choices.
The Audio vectors are probably the best bang for the buck in your short-list, along with the bigger Martens mentioned above.
There are 2 choices NOT mentioned that will easily outperform the excellent A-vectors & the Martens (etc):
*Perlisten 3 or 5 (5 is preferable, but whichever fits in your room). Vanishingly low compression and distortion even at high levels...
*Apertura Edena evolution, or Adamante -- this one is easily a couple of levels above the rest. Very fast, dynamic, extended and clear bass and a lovely midrange
Note that I go for dynamics, I listen to classical orchestra, i.e.complex music, and I too now have a relatively small room.
Enjoy the hunt!
