Hoping to get some help on which way to go here. I'm looking for more output. I had an ED A3-300 that I was very pleased with so I am about to make another purchase but I am undecided. My question is, wouldn't the ED A5-350 at 500w have more output than the HSU VTF-15 at 350w? What abot the Rythmik FV15 at 370w? My room is approx. 3400 sq ft, I'm 80% movies, 20% music.
