I cannot compare to another expy. I did enjoy the harmon system, I feel it was better balanced. The expy seems to boost vocals and lack low end. Switching to surround from stereo helps a little.Have you been in or owned a 18-21expy at all to note the difference btw the two systems?
I remember testing a ram with the harmon which sounded phenomenal, as well as a wagoneer with the Macintosh, though I thought the macs lows sounded gritty and choppy at times. Did u like the hk over b&o, are you rate them the same?
