Magnepan 3.7's versus 20.1's?

Here we go.

Before we digress, I suggest

Magnepan 3.7's versus 20.1's versus Tympani IVa's

please.

I would think the 3.7s will be a distant third to both.

Both require a lot of power, 300wpc to start, of quality power unless dynamics do not matter or your room is small, a hardwood floor etc. The 3.7 is a big slice of the 20.1, but not the whole pie. Close enough though that a well set up 3.6 ,3.7 will outperform a poorly set up 20.1.

Thanks for your input folks. I have sufficent amplification & a suitable sized room - & was leaning towards purchasing a pair of 20.1s. I just haven't had the chance to compare them to the 3.7s & wondered whether the 3.7s were as close in performance as some people seem to be suggesting.

I have owned Magneplanars on and off since I was in high school in 1979.

They are wonderful, but need power and are extremely sensitive to room placement.

So a well set up 1.7 might also outperform the 20's. Indeed, a well set up MMG might outperform the 20's in certain situations, neither of which says anything about the value of 3.7s.
