From ZERO to Hero?

@mrdecibel 
I only report what I have heard. Steve mentioned that using the Autoformers helped with Sound Quality even with his SS amps. I might give him or Pat a call to get further details.
I also know that Atma-Sphere recommends them for speakers with low impedance swings.
@OP, if only I had time to play around with my system would I install those autoformers.

To the OP. Are you hearing problems or issues with your system ? These transformers are made as band aids to help with the amplifier / speaker interface, when impedance issues are present. McIntosh is the only ss amp company making autoformers as part of their design.

+1 on this.

Thanks mrdecibel! No, not hearing any problems/issues. Always looking for the best possible sound

Your PSA amps are perfectly capable of driving the ML’s without breaking a sweat, especially because the ML’s have their own bass amp, you will only go backwards putting an Autoforformer between them and your PSA amps, I have tried them on my ML based system and the Autoformer’s sounded limp and soft compared to without.

As Mr D said, the Autoformers can provide a "band-aid" solution for amps that can’t or have trouble with a speakers impedance load, but your better off saving the money as Autoformers aren’t cheap, sell the amp, and get an amp that will be happy driving the speaker.

Thanks George!  As of now, those autoformers are definitely out.  Much appreciated!
