Magnepan 20.7's & Tube Amp

which one has more amps into 4 ohms?

which one has more amps into 4 ohms?

This is a bit of a trick question.

The amount of current will depend entirely on how much power the amp makes into 4 ohms. If 200 watts, the current will be 7.07 amps regardless of the amplifier involved, tube or solid state.

Wendell Diller always made a point of telling me that the best he every heard that speaker was at Johnathan Valin's house using a set of our MA-2s. What we found with Maggies in general is that if you want to play the speaker with tubes, keep the speaker cables between the amp and speaker really short- over a foot is too long! Place the amp with the speaker terminals facing the speaker's terminals and install the really short speaker cables.

This is a really good place to have monoblocks :)

Anyway, this gets you the best bass. Don't worry about vibration from the speaker; the amp will see very little. Maggie owners know what I'm talking about.

Ralph, wouldn't a set of Zero Autoformers be of help?

The MA-2s don't care, but on a lot of amps, yes. We are in Magnaplanar's back yard up here in the frozen wasteland, so we have a good number of local customers running M-60s on some of the smaller Maggies, and the ZEROs are how they do it.

Paul Speltz has a letter from Steve McCormick in which Steve states that although his amps have no problem doubling power into lower impedances, that they actually sound better if they are driving 4 ohms through Paul's autoformers (the ZERO). So the ZERO's help with a lot more than just our amps.

A Big high current  solid state amplifier would have much better grip ,control 
On the Panels.  I have used big Bat amplifiers  and the Pass labs 250.8 would be a 
A match as close to Ideal as you can get.  With s good tube preamp.
Even if not was not mentioned it should have been if you want to heard the truth.
