If you really like the basic sound of the 1.6, but, cannot move up in size to the 3.7, I take it that getting a subwoofer would also be problematic. That probably means you are looking for a small system with the sound of a dipole speaker. Perhaps an electrostatic/dynamic woofer hybrid would fit the bill. Martin Logan makes such systems, and to me, much better still, would be speakers from Sanders Sound. These are not small in size, but, they are considerably less imposing in looks than maggies.
Replacement for Maggie's?
So I have been thrilled with my magnepan 1.6's to the point that I have upgraded every component to the point that even the power conditioner costs more than the speakers. My question as the headline suggests is that where do I go from here for speakers? I love the Maggie sound for its wonderful depth, life like size, and soundstage. Dislike its lack of bass. The rest of my gear consists of Ayre C5xeMP, Ayre K5xe soon to be MP, Pass Labs X250, APC S15, Grover Huffman XLR's, Signal Cable bi wired speaker cables. Thanks
