I'm just here to say that I'm still thrilled with my Rivals. A buddy came over with the 12" 45 rpm of "For Those About to Rock" and the Rivals may have cracked the foundation. :) And the mids! The screaming mids! And the lows - the highs were there of course.
Then we put on the MFSL of Beck's Sea Change at a more reasonable volume level and the sound was just as impressive with a nicer more euphoric sound and sound stage.
Then back to hard rock to STP and the volume back up.
Then to Elton's Funeral for a Friend - Speakers Corner vs. UK OG DJM, one after another.
After that side 2 of a tri-color, Santa Maria of Axis Bold as Love and back down to a more reasonable voulme and WOW -= there is some magic ferry dust in that pressing. The 3D / sound stage was on another planet.
More to follow after that and it was permagrin for 3 hours until my wife came back from her hair appt and power off.
I've never heard a Klipsch Heritage so I can't make that comparison but what I can say that I still look forward to every listening session like it is an event. And it is.
