New Polk L800s Crackling/"Shrieking" with SDA

Had it not been for a retirement, I doubt they would have had them in the Legend line this time around.
I'm with you on the Massimo foot dragging and almost incompetence at running this company.
Hopefully a new owner will for an upgrade of the tweeter and a repeat in a "version 2". I think the (presumably) not great sales of the L800 was due to lack of proper marking and need for an in-home audition program setup, which some manufacturers have done before.
Plus, they really just needed to iron out the amplification issue. If it was just a matter of adding in two more conductors to the SDA cable to be able to use a BTL amplifier, that was an opportunity lost. It confused too many people in this day and aged where internally bridged amps are more common. Polk had no sufficient amps in the entire Sound United portfolio to recommend. Oops. Denon/Marantz receivers as well as their separate amps are all out of gas at or before 200W into 4 ohms.
This Denon receiver I'm using works, but it will not properly drive these things at anything above "medium loud", and every current compatible Denon/Marantz amp is similarly underpowered. I haven't had the distortion issue again, but the receiver is unhappy to go very loud, and listening is very volume constrained. When I put in some actual power again next week, hopefully it all goes well. I'll have a solid 800W on tap into 4 ohms, which should be enough.
Ummm...SDA speakers have always had restrictions on what amps are compatible. With the vintage SDA speakers one had to use an isolation transformer in order to use non-common ground amplification. With the current L800 the only restriction is dual differential amplification.
The Reference Marantz PM10 and the new 10 integrated amps have plenty of power. However, they are dual differential.
Another comment. Name me a pair of $6k speakers that includes an in home set up???Post edited by F1nut onPolitical Correctness'.........defined

That was my initial gut feeling. Too bad to put pro power on those speakers
