Wow, that it did something to your Mark Levinson amp!
Those amps died earlier :(. It is my other amp which up to now has been functional:

It is the one in the center. It is a 400 watt/channel class AB amp. Cost $20K before it got discontinued.

I will have to test it with another speaker to see what is going on.

Thinking about it, it could have been Roon glitching as well. Either way, it was a pretty bad scare!

Is there a way to do a measurement of this particular speaker with the Aiyama versus the ML? Would be interesting to see if the sweep changes when switching the amps.
I shipped this speaker back today so no chance of doing that. The ML amp weighs something like 100 pounds so it is not possible to move it to where the lab is. The AIYIMA for sure is changing the response. Audiohlic's Jamese Larson was testing amps with similar class D amp, and they found out a few months ago that it was changing response of the speakers he was measuring. So the effect is real.

"...people buying stories instead of a proper design..."

Any donations are much appreciated using: https://www.audiosciencereview.com/forum/index.php?threads/how-to-support-audio-science-review.8150/

What an sagacious turn of phrase! People have been sold and are buying stories instead of objective vetted: science, engineering, and production values -- sadly appears to be the standard for modern marketing at large...

The only interesting, and potentially credible iteration of the LS3/5A that I've come across, and it was only a perfunctory listen, isn't even technically an LS3/5A, is the Falcon Acoustics Q7 which has a deeper than 5A standard box to get the Q down to 0.7, and a more modern crossover...

No idea if it's any good; the approach appears sound but the price is steep for a dice roll on a promise of sound engineering, and 'a story '... The Raymond Cooke story is however quite compelling, from the BBC; to Wharfedale, then founding KEF, his AES papers, books, and engineering prowess were impressive...

Thanks always Amrim for the erudite analysis!

After reading the EDIT containing the listening & EQ review then this makes me think it's an even worse speaker than I imagined! Just not really a speaker to own under any situation!

Still they are better value for money than spending 2.5k on a set of Rogers, Falcon / Whoever!

I think I'd sooner have a pair of smaller Diamond 12 series and save even more money!!! Easy to buy, easy to use and shouldn't drop so badly in value if sold on later.

Many people appreciate the vintage character of the LS3/5a. It harkens back to a time when BBC studios and high-end audio systems around the world used this speaker.
Studios often use reference monitors such as the Rogers LS3/5a or other models with known non-linearity and precision. Sound engineers adjust their mixes on these monitors to ensure the sound is reproduced well on as many different systems as possible. Sound engineers make subjective decisions during the mixing process. These decisions can be based on the specific characteristics of the monitor. The Rogers LS3/5a has earned its reputation over the years due to its use in professional studios and its suitability for specific applications. The historical context can contribute to people evaluating its sound characteristics as positive. When these mixes are played on a good speaker with a linear characteristic, unexpected results may occur.
Here is my idea to carry out targeted equalization (equalizer adjustment) and integrate it into the preamplifier.
The result is an acoustic copy of the LS3/5a, where the old recordings sound the way the sound engineer wanted them to. here is my result:

You might want to move this to the legitimate LS3/5A review thread. This is a review of an utterly cr** clone whose only similarity with the BBC specification is the cabinet size!

The LS3/5a sound and prescense owe a fair bt to the main driver being recessed behind the baffle, it would be hard to get the same 'LS3/5a' effect with drivers mounted on the front.
