I am looking at amps for some planar speakers, which can be harder to drive (Maganepan 1.7.)
Also want to get them to sound as sweet as I know they can.
How well would these amps work? Any experience out there with this model? Does it have the high current needed?

  One of the all time classic combos. Effortless dynamic. Sweet ? If ya want to add some color a tubed CDP or Pre would do that. If it were me a tubed CDP would do the trick with a Bryston Preamp. Or just update to SST2.

Yep, good match. The 7B should be enough power for the Maggies. I would go for at least SST, though. It sounds better, imo.

A set of Bryston 7B ST should be a great match for the Maganepan speakers.  One advantage of the 7B ST is that you can switch the amp between series and parrallel configuration.  The parrallel configuration is ideal for driving speakers in the 1 to 3 ohm range.  In the newer amps the configuration is hardwired and cannot be changed without sending the amp back to Bryston.

One point to be made is the Maggies are 'planar magnetic' and although they drop down to lower impedances they are a very resistive load (as opposed to reactive) and therefor require large voltage swings. So definitely use the SERIES mode with the older 7B's on the Maggies if maximum drive and control is required.

Hi James,
I was wondering that,what was the main reason to eliminate the switch for this option on newer models?
Thanks,

We found with the newer designs and the newer transformers we were able to drive lower impedances without the need for a switch in the circuit. So unless your looking at seriously low impedances over large frequency ranges the standard version of the 7B is more than adequate.

You have to be careful with the series/parallel switch because at higher impedances (8 ohms) a 7B would only be putting out about 180 watts in the parallel mode.
