Does a turntable mat make any difference?

Mijo, you write, “I cannot believe this (inserting the Bricasti at 5kHz) won’t be an improvement.” Thus I guarantee you will perceive it as an improvement. I personally don’t agree with forcing a speaker to create a flat in-room response regardless of driver limitations, especially in service to a processor, but you already know that. I think when your brilliance control got hot, the speaker was telling you to lay off. Anyway, I’d love to hear the results. Also, when S’phile analyzed a full range SL speaker (forgot what amp and which model SL), it measured very flat out to 20kHz, without high frequency augmentation. Maybe that was at a SPL well below what you like.

IIRC, I measured 50 ohms impedance on my SLs at 100 Hz. But don’t hold me to that until I get home from from Vieques (a small island near Puerto Rico) and consult my data. (It might have been 50 ohms at 50 Hz.)

Agree on Lee Morgan.

Many threads on this subject with some of the same contributors saying some of the same things. More to come I’m sure.
