I could pull the trigger on the 2905, but several things concern me...
1. I really enjoy ENJOY my Summits. The presentation I feel is "cleaner" than the Quads at the expense of perhaps being too lean. The Quads presented less hifi and more natural.
2. I know my Summits inside and out, I've played with them endlessly and I've tried so many amps, preamps, and sources on them. I know what they like to my ears... going with something new like the 2905 would bring me back to noobie level - which isn't a bad thing, but I'm comfortable with my Summits as they are.
3. Reliability of my Summits have been proven, whereas I've read several failures on the Quads. Even though my potential 2905 is brand new from an authorized dealer, 2 years is the extent of the warranty. And after this recent debacle with my rectifier tube, I sure as heck don't want to deal with system downtime.
4. If I get the 2905, I can't get the 805C.. nor do I think it would be smart to get such an amp on a speaker that is relatively inefficient at 87db. AND - with all the hoopla regarding the 805C, if they can take my Summits to another level, that would be AWESOME.
I'm mulling it over.... do I get the 2905? Do I stick with the Summits and see how it does with the 805C?
Too many questions this week... life was simpler last week.
