Hi, All

have some question to ask you!
Mcintosh MA-6200 can drive Rogers LS3/5A 15 ohms?
who have experience with both please advise me

I read from other forum, and found MA-6200 is made from 1978 to 1991
and How to know which MA-6200 is the lastest?
look from serial number?
what number is the lastest?

many many thanks

Hi Munkong, LS3/5A 15 Ohms is on my speaker hunting list, I do not have MA 6200 too, Have you tried connecting The Rogers to C-16 Ohm MA port?
How about the sound?

Have you tried aksing the same question on thaiaudioclub.net as wll as many other local websites?

I had two MA6200s and loved them with the B&W 804. Currently using MA6600, for me the 6200 is one of the most beautiful Mcs.

The amp in the MA6200 is the same as the MAC4100, 4200,4300, receivers as well as the MC752 and MC754 amps. All these will easily drive speaker loads down to 2.5 ohms and I see no reason there would be any issue with the BBC monitor's 15 ohm load.

The 6200's amp module is the MC752. At 75 watts its 25 wpc less than the 4300/754 module. Same OTL configuration. It will drive any of the BBC spec speakers beautifully.
 
Sorry check the specs and schematics carefully. The output circuit is virtually identical in the mentioned amps and receivers.
 
From Roger Russell's page. What am I missing?

Study the MAC4300 schematic carefully, think of the Clarion hires marketing goals we had to put up with, and we will leave it at that.
 
The MA-6200 is the same for all production years. It does not have barrier strip taps for specified impedance. Power Guard is an "autoformer" and does not require a manual selection. I have had one since 1978 and have easily used it with Rogers LS3/5A's ever since. If you can get one at a good price, do so. They seem to run off to the pacific rim for a reason. Get yours. Enjoy!

Just wanted to clear this up, as Powerguard is NOT an autoformer. It is a protection circuit. Also, the MA6200 DOES NOT have autoformers.
