Thanks for taking the time to post.
I find it strange the 1801 bass was in the same league as the larger Dynaudio Woofer. Those woofers had a very good motor assembly with shorting rings in the right places. Perhaps the detriment could be the soft poly cone. Certainly there will be some flex - even at lower frequencies.
The only negative I found is they punish poor recordings, highlighting all the deficiencies. Why can't every artist record to a minimum high standard? I've never understood this.
I feel your pain too. This is indeed frustrating. Eventually my collection of daily use CDs encompasses the 1% of decent recordings available. The other 99% of recordings find very sparse use in my system. I would really like to have a good recording of The Emotions "Best of My Love". It's a fabulous piece of music

, but the recording quality is very average

. Hm, I wonder if the LP would sound any better.
I believe it's a safe assumption that a minimum quality standard doesn't exist because...
1. Most consumers don't really care, and can't discern the difference between a good recording and a bad recording.
I recall reading an article about the Yamaha NS100 being commonly used in recording studio's because they are considered a "benchmark" for what folks have in their homes - not because the NS100 is a good sounding speaker. Genalec monitors are also quiet expensive/esteemed, and... have been displaced by products from myself & Jim Salk.
2. Good recordings are expensive. Good microphones, dead-quiet studio's, and good "source gear" add to the cost.
3. Obtaining a consensus regarding recording quality would be even more difficult than getting component manufacturers to convey consistent truth about their response curves and/distortion measurements. And... even IF the standards were more rigorous, would they truly meet the scrutiny of the human ear?
A couple days ago I was pondering the concept that the human ear is truly able to discern a very large quantity of information - often more than measurement gear. While there are some incredible advances in measurement electronics, a well trained human ear is surprisingly keen. The audible character of coupling capacitors is probably the arena where the human ear remains dominant. The human ear knows that 2 capacitors having the same Dielectric Absorption and Electrical Series Resistance don't always sound the same
