I had a pair of Tyler Accoustic Ref. Monitors. These speakers did not sound good (no air, felt as if there were layers or filters on the sound) with my tube gear (Graaf GM20 OTL amp, Graaf 13.5B preamp, Copland 289 HDCD, FMS cables). In comparison, my 15-year old ProAc studio-2s sounded many times superior. To be fair the Studio-2 are (24-H X 11-W X 12-D), quite a bit larger than these.
