Brian,
I sent you an email but your spam blocker kicked it back. Call me at 615 269 5424 if you want to discuss it.

Mechans,
Five months ago, I mated a pair of 201's to my Vienna Acoustic Mahlers. Two 10 inch woofers, that many amps find difficult to control, mount to the side of each speaker. I find that the 201's unwaveringly control these woofers' magnificent perturbances. They absolutely deny deviations from the source. IMO, one cannot compare the 201s to the Model 10s or 12s. These perform in another league. They perform more like the 302s.

Allhaildawg,

These/they = ?? Are you saying that the 201's are more like the 302's? Or the 10's/12's more like the 302's. Forgive me, but I am totally confused by your post.

I've now had 201's for about a month with close to 100hrs, and consistent with my experience on the Concentra II these amps are very quiet IMO very much a charateristic of all JRDG amps....so one could assume the same for the 501's.

They'll still need a lot more time to realize their full potential (as I'm still running them in), but my impressions thus far are that the highs are superb and these are fairly accurate amps.

I've got a pair of very demanding MBL 111B speakers (rated at 81db sensitivity, ouch!) and attempted using my Concentra II at first(for 2 weeks)to drive these German babies and whilst the integrated amp is no slouch they just could not control and perform they way they kicked ass on the ProAc's before them. In came the 201's patnering the Concentra in a biamp setup (with 201 on the high/mid and Concentra low's) and this was more like it. If you're familiar with MBL's you'll know that these are power hungry speakers which is why you see the big beefy MBL amps normally partnered with these speakers and 201's held their own which speaks a lot for these pair of "A4 size" amp.

The dealer where I live has a setup of the Synergy IIi, 501 or 201 with the MBL 111B or 101E which is one of the best setup I've heard so far.

Hi,

I heard the 201's a few times and the 501's for a few hours. The 201's have problems to control very demmanding speakers with a big driver/s. They are a little leaner, bright and make you feel they are quicker, more focused, more detailed, than the 501's. I never had the feeling that they are a real 250Wpc, like others transistors amps I know. The 501's is more natural sounding and have more power than the 201's. They have a better balance, dynamics, low level resolution and a better control in the bass frequences.

I hope this help,

Tomer
