I'm not familiar with that particular speaker but I'm quite familiar with its little brother:

One of my buddies uses these in conjunction with a Jolida (302?) and Marantz 5001 cd player for a nice budget office system. As far as build quality goes I can tell you that the Model 5 is a contender, constructed thoughtfully and with much attention to detail. The mids are lush though not overreaching and the highs are appropriate. Between the amp and the speaker their are low frequency deficiencies but that's to be expected in a monitor and medium watt tube amp. The smaller Model 5 with different drivers will obviously have some different characteristics but I'd imagine the voicings reflecting the Omega "house sound" will be similar.
