I have been achieving some of that 'magic' Fcrowder mentions with a combo of Steelhead running thru the MM input, to the Lamm L2, using the latest Titan. Not saying it is the 'best' but the combo achieves more than the sum of its parts. And, while I appreciate that these are 'production' units they probably work fine in a range of other systems. The Lamm, used, is a bargain, and while the Steelhead is not so readily available used (yet), it offers enormous flexibility. It is an interesting combo. (Haven't tried some of the others mentioned).
