Should I upgrade?

Thanks guys for the responses. I am indeed using BDR cones under all of my equipment currently and find that they really help. My Innersound esl amp is the middle version with the power switch on the front. I just talked to a gentleman with Innersound and he mentioned that mine is most likely the same internally as the current version with the exception of the power switch on the front. As soon as I posted the question last night, I saw that 89lotus also asked about a cdp upgrade while including the Audio Aero Prima on his short list. How do you think my Cary would compare to the Prima or would it be like comparing apples to oranges because the Cary is ss and the Prima is tubed? Did you happen to compare the Prima to a Cary ss cdp Warrenh? Again, thanks in advance for suggestions!

I have the Audio Aero Prima..I talk about it adnauseam, I know, but it's one hellava cdp. Read my review. I can turn you on to where to buy it at a killer price, backed, of course, with great service and tlc. peace, warren

I know from personal experience that the Rogue 99 is extremely sensitive to what is supporting it. Putting it on BDR #4 cones really tightened the bass for me and helped the PRAT substantially. If you haven't already done so, I recomment trying this tweak first... I used the 99 in a system with the InnerSound Eros and ESL amp; the bass was total mush until I installed the BDR cones.

Also, if you're using an early version of the ESL amp, it had some problems with bass control. The problems had to do with the feedback configuration (or lack of it) and was fixed in the version 2. I believe that early versions can be updated by InnerSound.
