I just recieved my amps today the jolida jd-3000a 200wwt/ch of tube power and wow ,omg what a change .I replaced a my wyred 4 sound st500/250 wtt /ch ice amp that did a great job .But let me tell you if you can mix tubes with the clszii the musical difference is amazing . The clszii love high current and these amps deliver and the bass in the speakers seemed come alive .I set them up and took my time since tubes are new to me .the set up was easy and the biasing of the amps was easy to .Now for the listening ,from Lou Rawls greatest hit to the zack brown band to superman the movie by john williams.Polar Express the xmas movie ,the the best Frank Sinatra and the music seemed so open and real .... Im not a pro at this reviewing stuff and my spelling is poor ...but my ears work great and this combo of jolida mono amps and the clszii make a very happy couple and the music they make sounds live !!!! pics to come when I get back from my fire dept shifts :music::music:
