This evening I got a nice reminder about the importance of component matching. A few weeks back I got a pair of Klipsch Tangent 300 speakers. One of the horns was broken and I used some epoxy to put it back together. I had been playing them with my bench amp (a Technics SU-V76) and for a few days. I found them to be everything people seem to hate about Klipsch speakers (BTW, I love Klipsch speakers, Hereseys are my daily drivers). They were "shouty" even at 40 or 50 degrees of axis. I kept hoping they would break in. Then, I started wondering if Crites Titanium diaphragms would fit this particular horn. I felt they had potential, but really needed some help.
This evening, in an unrelated project, I hooked up a still disassembled Pioneer SX-450. I wanted to see if the DeOxit bath had been completely effective or if it was going to need another shot. I wasn't even thinking about the speakers, just using them because they were what was on hand at the moment. I cranked up the Fleetwood Mac and it was revelatory. They went from sounding like PA speakers that I couldn't get within ten feet of to sounding like reference monitors. Directly on axis they weren't even the slightest bit fatiguing. Everything I thought might be there but wasn't revealing itself with the Technics came to the front with the Pioneer.
BTW, the Technics has sounded really great with JBLs and ADS, so it's not an issue with that amp. Now I really can't wait to hear the Klipsches with tubes!
