My recommendation is to build all new crossovers using the MV Audio Lab design. It makes a big difference

The HPM-100s pushed upper mids and rolled off highs are well documented here on AK. Find the posts from Ziltch, there are many.

Mark, I built this design. Very impressive. https://www.mvaudiolabs.com/speakers/untamed-vintage-pioneer-hpm-100/ A quick audio demo afterwards:

@markthefixer, nice find on that post! I still have that exact system, but with an SX-1980 running the show. I have a set of first gen SDA SRS on the B channel. I also replaced the HPM-100 crossover with an all new design. That was a fun project to work on.

Check out this demo of the HPM-100s with the MV Audio Lab crossovers installed. Sounds pretty darn good to me.

OK. Time to break out the soldering iron.

Hi Mark, I thoroughly cleaned both the rear jack and the plug off the PL-560. No difference. I noticed when I remove the plug and put it back in, it takes between 15-20 seconds for the excess treble to pop back in. Once it, it pretty much stays that way, although sometimes it goes back out...

Hi Mark, Yes, left channel cable meaning when I disconnect the left channel of my PL-560 from the SX-1980 and then plug it back in, the treble is normal again. Phono 1. You're saying to clean the Phono 1 input selector button and the Phono 1 cartridge load attenuators?

For some reason while playing records, the treble response on the L channel only gets extremely bright. When I unplug the L channel cable in the rear of the unit and then plug it back in, the issue goes away and the treble balance between the L and R is back to normal...for a short while. Then...

I stumbled upon this 9/11 tribute song from a reddit board on music theory. They were talking about how the drummer plays a really cool groove. Anyway, I have to say.. this is the most impressive 9/11 tribute song I've heard. The ending makes the hair on the back of my neck stand up...

To my ears, old Klipsch is not nearly as good as modern Klipsch.

I am surprised so many HPM-100 owners here on AK don't know about this. There is a guy who painstakingly measured the woofer/midrange/tweeter performance, cabinet tuning, and designed from scratch an all-new HPM-100 crossover. His goal was to fix the inherent issues and limitations of the stock...

I've gone full circle on vinyl. I got into the whole vinyl revitalization thing a while back, but at the end of the day, I came back to digital for all the reasons that made the format popular to begin with.

I love the idea of using modern technology to design all new crossovers for vintage 70s speakers. New crossovers that replace some of the 70s era primitive designs rife with phase issues, overly bright voicing, etc.
