Agreed a system needs to play all kinds of recordings well. You want a system that can show off good recordings, but not so analytical that your average recording sounds horrible. It’s a balance, just like audiophiles have to look at system synergy, designers have to look at synergy within components. Even with that said though there are other factors that comes into play, crossovers are inherently resonant structures. Finding the balance where you aren’t exciting those resonances created by the filter and driver can be very difficult especially because you often can’t see it in the measurements. And some drivers are much more difficult to work with, the sapphire tweeter being a great example. While it looks great on paper there are a lot of resonances within the driver that crossovers excite let alone the own resonances of the filter. We’ve made M100 sound all sorts of different ways over the years (including under Clayton, and all measuring linear) and I would say we haven’t cracked the full code until now. But man is it impressive, the things this tweeter can do yet at the same time it’s smooth and liquid sounding. I’ve only heard the SOTA tweeters do these things and even those, don’t have the utter lack of a sound that ceramic does.
I hissed into my rug to see and it didn’t hiss back so I think it’s good

lol. On a real note I got those rugs at Costco and they do a terrific job at absorption. And yes before I brought them home I 100% spoke into them to see how well they deadened my voice. The floor is by far the worst reflection point. It’s because the majority of time it’s too close in time for your brain to separate it as a reflection so it creates a smearing effect both in sound stage and detail and yes it can make things sharp to, especially with wide dispersion speakers. When I got the rugs it made my center image lock on with much better space around it along with softening my transients to a more natural degree. I’ll have to try one of the jute rugs like you suggest.
