Yea, I'd say you are. The Summits, IMO, are much better than the Vantages. If only for the much improved woofer/panel integration. Though that's nuts you would get such expensive speakers without hearing them. I have a pair. They are pretty darn close to full-range, 24-20khz, each speaker having two 10" alum woofers powered, each of which is powered by its own 200w ice amp.
There are a few tough things about them. You will need considerable space between the speakers and boundaries. Im talking about a few feet, if not more, from both side walls and front wall. They want a bigger room too. I highly recommend some treatments, especially for front wall. Takes research, and dependent on how far you are from certain boundaries. (For instance if you are close to rear wall, untreated, those reflections coming too quickly will sound more like smearing than ambience).
They are beamy. Depending on setup, size of room, you are talking about a sweet spot from only single person to perhaps three people max.
They want a high-current amp. They drop to 0.7 ohm. Everyone always told me to get the best I could afford, but I always went with less. I pretty much always have had the least expensive amplification (and electronics in general) of any Summit owners I know of.
Congrats. They were my favorite speakers I ever listened to. And I listened to some REALLY expensive speakers, like Dyn Evidences and Focal Grande Utopias. However, I listen to 99.9% acoustical music. No other speakers I heard could replicate the decay of a plucked string or struck piano note as well. IMO of course. Low-level detail is phenomenal.
Unfortunately, the room I put my speakers into really sucks. Im going to experiment some more, or do some re-re-arranging to put them in the living room. Will be far less than ideal, but it can't be any worse. Bummer.
Does SD stand for San Diego?
