Acoustic Treatment
Acoustically not a great living room. I have the speakers on the short wall and the listening chair only about 1ft out from the opposing short wall. The short wall behind me unfortunately has 2 large windows that I am definitely going to have to buy blinds for - just get those large flat glass surfaces covered up. I have a large 10x14 oriental run laid down which helps and a nice fabric sofa along the long wall which also helps I suppose. As this is an upscale (rental) I cannot nor want to use sound panels for aesthetic reasons. The higher ceiling has also resulted in some lost bass impact vs. my old apartment but NYC apartments are always a big compromise :(
Listening Impressions
The Omegas are very fast and detailed but also very natural sounding. Unbelievable mid-range and decent bass for a single driver. Excels at guitar, sax, drums, piano but pretty much anything you want to throw at them. I think they are really great with 300Bs but I also like them with EL84s and would be very curious to hear them driven by quality 805 SETs. I really think the Omegas like more power - 30-40 watts of tube power is probably the sweet spot.
Other Comments
The most noticable improvements in my system have come from tube rolling. NOS Telefunken ECC801s tubes made the Manley Shrimp pre absolutely come alive. The amps have the full treatment - Sophia Carbon plate 300bs, RCA or Ken Rad VT-231s, RCA VT-229s and NOS RCA 5U4GBs
