Dynaco ST-70 and Magneplanar 1.6QR

My MG 1.6 sound much better with a 350 watt Adcom amp than with a 100 watt Adcom amp having similar specs except for power. The message is clear...get more watts.

Maggies need much more power. You could try a good powered sub. If you run from the pre-amp to the sub to the amp, you can filter out all signals below a certain level (100hz?) which will greatly alleviate the strain on the 70. According to Janis Subwoofers, if you eliminate all bass below 100hz, you effectively quadrupal the power available to the speakers!

Thanks for all the great advice. I am a novice in the hi fi area, but I realize that I am plummeting into the rabbit hole fast. ... I got the Maggie 1.6, loving the open sound, but felt that they needed some warmth, and therefore combined them with the Dyna - 70. It actually sounds good, as long as the music is not to demanding, and kept low...

So here is my probem I guess, is there any tube amp I could afford that provides 100W per channel or more? , ( would that do the trick?)
budget is about 1k....

alternatively, on the same budget, is there a solid state amp with warmth...? , again, thanks alot for all your advice..

As far as solid state in your price range, you might want to consider something like a McCormack DNA 1 (100 wpc)or DNA 125 (125 wpc). Check the archives for other people's opinions on these amps. Perhaps you could introduce tubes via a preamp? Good luck and have fun.

If you are open to experimentation, you could try a pre-owned B&K ST140 @105 wpc. Another possibility is one of the older SA series hybrid amps by Counterpoint.

I drove an older pair of MGIIIs with an ST140 for several years, in a smallish room. As long as your volume demands aren't huge, it can do a very adequate job. Buying a used one will still leave lots left over in your budget for quality cables.
