The HPM-100s are a very well rounded, very forgiving speaker. I am listening to The Alan Parons Project right now through four of them powered by a Pioneer SX-1010 and using a Nakamichi CD-4 CD player. Yes they are excellent for rock and roll, but I also like them for jazz and female vocals. Now having said that...It is possible to make the HPM-100s sound bad. Different receiver/amps, CD players, Turntable/cartridge combo, and inter-connects will have different effects on these speakers like any other. I have tried many many combinations. For example, I used a Kenwood KR-6400 receiver for awhile, it made the speakers strong on mids, but muddy on bass, my SX-980 Pioneer receiver makes them sound very bright and fatiguing. I'm getting ready to try them with a Yamaha CR-2020 after I get it back from Merrylander. My Sony CDP-CA9ES CD player makes them sound incredible for reproducing the acoustic guitar, but vocals seem to get lost. My Harman Kardon HD-500 is great for vocals, but looses it in the bass. It's not just the speakers but the whole package. I don't want to get in to speaaker cables and inter-connects as I don't want to start a war. I've said this a million times but what it really comes down to is DO THEY SOUND GOOD TO YOU???? That's what's most inportant!!!!! That's my story and I'm sticking to it!
Rock On!
