Hey all, first post here, but I've been stealing info for a while and used some of the advice off of here to get to where I am now with my system. and at my advanced age I am proud to say I now have the finest system that I have ever owned, and one of the top 3 or 4 I've heard. I, too, changed out the caps on my 1.7's. I thought my maggies were a bit too shrill on the upper and middle end so I used caps that would smooth it out just a bit. Imaging and airiness without the bite was the result and I couldn't be happier. I mostly listen to 2 channel music, but I do have the CC5 and MC1's from Magnepan for the surround channels. Processing and power to the rear and center channels is provided by an Anthem MRX710, while the front 1.7's are currently powered by an Emotiva XPR-2 linked to the Anthem. The 1.7's are power hungry beasts and, before I got the XPR I tried to run them off the Anthem, which is a great unit, but at high volumes the protection circuit would kick in. I also tried running them off of an ancient Sansui AU9500, and an older ST series B&K but couldn't get what I thought I should get out of the maggies. I even had a friend bring over a tube MacIntosh that didnt make the grade either. I tried out an Emotiva XPA-2 and I finally got them to sing! When the dealer offered me a floor model deal on the XPR that I couldn't resist that is what I stuck with. The hunt for a subwoofer, even though the 1.7's aren't too bad on the bottom end, was the most difficult. Don't go by the subwoofer reviews for this. You need to hear it with your system. I went through 5 different set ups at the dealer, including REL, Rythmik, and SVS, but the bass kept its overtones going after the maggies were all done. They all muddied up the music a bit. I finally found a non-ported Martin Logan Dynamo 700 that was very precise, was extrememly reasonable on cost, had a great built in amp and the adjustables that I needed and I was finished....I thought. To me everything sounded great. But the one thing that I had put off while trying to get all the right components together was doing the room correction. The Anthem ARC room correction is acclaimed as one of the best. And, knowing that the Magnepans are real sensitive to placement, I decided to run the ARC. Incredible! The magic finally happened. Anyway, if you are thinking of getting the 1.7's or 1.7i's just stop thinking and do it. I realize I've rambled on but I hope that there has been a bit of info that may be valuable to someone here as previous posts were for me. All the best.
