"I listened to some Heresys yesterday. Did not like them at all. No real clarity to me. Not compared to the speakers I have. Listened on an old Marantz 2250 something."
When I had my Marantz 2252B driving my Heresys, I liked the "warmish" sound but I knew they were lacking detail in spades. I added an Acurus A250 to the mix and new I was getting closer to what I wanted. More punch and plenty of detail with a dead on neutral tone. Sold the 2252B and moved the A250 to another rig after I got my Luxman R-117 and the Heresys have never sounded better to this date. Soundstage widened and deepened, imaging was spot on even with less desirable recordings, mids were sweet and velvety and detailed, highs were extended without any shrillness, and the midbass punch was at a level I never expected.
I guess component matching is as important as "they" say.
Just my thoughts.
