The panel is a sizable portion of what it costs to build a ML speaker system. I'm happy that ML is willing to make panels for older speakers (not necessarily true for other parts, though). Like with an automobile, it's a judgement call whether you want to invest in parts to restore the old, or move on to a new. I'm not convinced panels need replacing as often as some people suggest here though.
I don't think it's just a matter of panel size. My CLS II panel that I stupidly knocked over and fell on top of cost a lot more than $995, can't remember the exact figure. Not only is it large, it has different sized, stagger tuned sub sections. Some panels have finer stater pitch than others.
Inflation has always been a thing. Sometimes it is high, sometimes low. There are many things that affect it, it isn't just one thing. Government fiscal and monetary policies, sure (the Fed controls monetary policy and they're supposed to be independent of the elected government), but also unexpected supply chain disruptions, pressure on salaries (everyone wants to make more money), natural disasters, wars, greedy sellers and manufacturers (it does happen). There's very little we as individuals can do to affect it, other than not asking for raises and not buying things we think are priced too high. It's not helpful being angry about it. Everything costs a lot more than it did 30 years ago, but I'm making a lot more money than I did 30 years ago. If you can keep up with it, or stay ahead of it, you'll be OK.
"Audiophilliac" Steve Gutenberg did a video a year or two ago pushing back on the notion that hi fi is so outrageously priced now. He compared a McIntosh piece from the 1960's with a reboot of it, might have been the MC275. It cost hundreds back then, thousands now, but when you apply the rate of inflation each year it's about in line. When I first got into high end audio ("perfectionist" audio back then, I think it was Harry Pearson who first applied the term "high end") and lusted after the Infinity Servo Static system, it cost around $1600, about the same as a new Volkswagen bug. What does a budget automobile cost now? Probably almost $20,000. Where I live, a starter home is at least $200,000. Thought of in those terms, the prices of hi fi don't seem so bad.
The good news is, buying an older pair of ML 'stats and repaneling them can be a good and economically viable option. I see CLS, CLS II, CLS IIz's, etc. for around 2 grand. As long as I can get panels if I need them, I'm fine with mine.
