Thank you for your candidness; I'm considering Klipsch Heresy's to use with a circa 1972 Marantz 2010.
Having grown up in the late 60's early 70's; I remember having two complete discrete 4 channel systems.
Also was a big fan of Henry Koss (& Ed Vilchur); as in Pro4AA, AR3A, KLH17, Original Advent Loudspeaker,etc.
All of which I have owned along with that era's Marantz gear, Craig 4 Channel 8 Track, Marantz 6300 with Shibata stylus, CD-4 Demodulator, etc.
