Ok ML CLS and SET amp owners - interesting ?

I own Wright 3.5 SET tube monoblock amps. They put out 4 watts and up to 8 peak. I love the way they sound. I want to try some Martin Logan CLS and while it seems crazy to think they both could work together I ask this question.

The CLS's are 86 db effecient and have a 4 ohm nominal impedience. They drop down to as low 1.5 - 2 ohms. OK, no way my Wright would work as it, but what if I purchased the Paul Speltz Zero Autoformers. I understand it raises the speaker impedience the amps see up to 2X, 3X or 4X.

How does increasing the CLS's from their nominal 2-4 ohms to 8-16 ohms increase the functional effeciency of the speaker? Does this even ring true?

Would my wonderful Wright amps then "work" well with the CLS's. Think this would be a match made in heaven if possible.

My understanding is the autoformers actually lower the efficiency of the speaker. I would contact Mr Speltz for an accurate answer.

I own CLS IIz's with a SFI Power 2. I also biamp. I think what you are attempting is an interesting experiment, but I would not bet the farm on it. A lot does come down to how loud you listen (I really like the CLS's at low levels).
