The -25db I put on the output, because the room can't handle much power, and just a trial to keep the fans working less.
I will get tomorrow a pair of I-tech 5000HD from a local AV company and try them out. Based on papers they have signal-to-noise >112 and THD 0.1% , while the I-tech 4x3500HD has signal-to-noise >108 and THD 0.35%,
So on papers, these should be less floor noise, and I already tested the fan noise, and it's 5 db less on them both compared to the 4x3500HD.
I will update the thread once I did my test.
