Assuming you are referring to the high-gain Kegons, and not the low-gain Kegons or the Kegon Balanced, and the newer high-efficiency [hemp driver] AN/E SEC Signatures then… well… maybe this is true for all the Kegon and all the AN/E speakers…

The AN/E sound will be more dynamic and somewhat less resolution and, if in corners, will sound like they have a wider range of frequencies

The Coltrane sound will be the opposite: less dynamic, more resolution and somewhat more reticent on the lower end.

In a small room, the Coltrane will be very intimate, the AN/E very enjoyable. In a larger room the Kegons will run out of steam on the Coltranes, but really just be kicking in on the AN.

Hope this helps,

Could I please get an answer from you? I am very curious.

How would you compare the sound of 22W Kegons driving AN/E SEC Signatures vs. driving Marten Coltranes?

Thank you for leaving aside my infatuations

To tell you the truth, we have not heard the old ML2 outside of show conditions. We are, though, aware that a number of people, including you on your site:

http://www.goodsoundclub.com/Forums/ShowPost.aspx?PostID=1096

think that the differences were extensive enough between the ML2 and ML2.1 that people might prefer the older flavor over the new one. That the differences may be so large that some might be consider them to be two different amps is unfortunate, and will cause a little confusion in the marketplace, but, hey, what is a little more confusion in the swirling chaos of audipophiledom?

That said, as you mention might be the case in the referenced thread or somewhere on your site, whatever the differences between the old and new versions may be, the new ML2.1 still smokes the competition at their price point. We are very happy with it here.

BTW, We did seriously consider getting your ML2s that you had up on your site way back when - but could not afford it at the time. Not that we can afford it now either, but someday we will have some extra cash when one of the plastic-binding-post ML2’s become available and then we can have a lengthy shootout and see what we hear - or is it: hear what we see?

Thanks again for your post,
Mike

I would leave aside your infatuation with 18W SET driving the sub 90db speakers that use funny drivers. I would like to ask something else. You, as the Lamm dealer, how do you find the sound of the new Lamm ML2.1 compare to the older Lamm ML2?
