Dynaudio Confidence 5 or Confidence 1 for this room????

Hello to all! I have a pair of C5's and was frustrated for the longest time -tried lots of different speaker cables, acoustic panels to treat my room ( 13.5 x 24 x 8 feet) and a bunch of different amplifiers. After experimenting for 2 years in a row I finally got them to sing right, and it didn't even take that much power as everyone believes. I am using a NAD Masters M3 integr. amplifier, fine tuned with Furutech PADIS fuses and Kimber Select KS1021 WBT-nextgen to replace the stock bridge, Nordost TYR XLR in connection to the SACD player, all power cords are PS Audio AC-5 ( pcocc). I just replaced my Nordost SPM speaker cables with the Monarchy Audio PCOCC speaker cable ( it was just $99USD on audiogon) now the C5 sounds fantastic. Those PCOCC speaker cables made a huge difference- unbelievable as they are the cheapest link in my chain! I am so glad I didn't give up on the Confidence 5- they finally sound right- very much like my AKG 701 headphones, smooth, super silky, nice tight but well presented bass, no coloration whatsoever and no boominess! I guess when the cables are right you don't need the big fat amplification. I get better sonic results with my M3 in combination with the C5 than I ever got out of my Krell power amps ( KAV500 bridged)- they where very powerful, but it was overwhelming, just not right- resulting in a brutal punchy bass without any silky smoothness. My advice-try a bunch of different speaker cables- cardas golden reference if you want to spend some more money. and place the C5 close to the rear wall ( about a foot distance to the wall- about 10 feet apart and angled in to your position) they don't care so much about distance to the side walls. Cheers and enjoy!
