can I get some opinions - bass on magnepan mg20.1

I had the same concern when I bought a new pair of 3.6's a few years ago, but they opened up and developed a rich, full bass within 200 hours or so. Partly it was a matter of adjusting to tighter, less-bloaty bass than I was used to hearing from cone woofers, but the Maggies absolutely got bigger and better all over as they broke in.

Magnepans, and their bass response, are usually extremely sensitive to room positioning. A slight change could completely alter your experience if you get it just right, so you may want to keep working at that. (Check the Magnepan site... I think they have placement recommendations.)

I upgraded to a new power cord on my Spectron amp, which opened up the bass considerably. (It was a DCCA Extreme Reference.) World of difference, with much more slam and authority.

I used to share the same point of view - that the speakers needed more bass - and went so far as to hook up my 5.1 system's subwoofer. But with a few changes, I found that I no longer needed it at all.

I've got 20.1's as well, and I don't find they are lacking for bass. When I listen to music that has bass, it is really there. When I listen to bass shy music, I am offering wondering where is the bass. They are great at presenting whatever is there.

I am also bi-amping, and that made the speakers quite a bit more dynamic and open.

Best, Peter

PS - ultimately, you'll want to get a pair of Mye stands for your Maggies. That will clean up the bass considerably. But it sounds like you are still in break-in mode (I bought mine used and didn't have that problem).

I bought mine used also and had to make several adjustments. First I went into my pre/pro and reset the bass so that the crossovers were sending more bass to the maggies and less to the subwoofer. Second, I got the interconnects and speaker cables off the floor and on to some very professional upside down yogurt containers (it really did help). Third, I have ordered the Mye Stands and last, if I can afford it, will change power cords on the Krell Amps as another contributer mentioned above. I worked quite a while with placement also but the other changes made the biggest difference. The 20.1s can handle a LOT of bass which is usually drained off into the sub. My sub is boomy but the Maggies are quite clear and tight. Hope it helps
