driving a hybrid puts one in a quandry. The ideal amp for the panels is not the ideal amp for the woofer. Here's my choice krell KSA 100 on bottom and CJ premier 11a on top or ARC VT100 full range.

I drive a pair of CLS11z with 2 Classe DR 8 amps run in mono.Stable and smooth.You could try the same but in stereo ,one amp to the panels, one amp to the woofers to keep the voice of the amp and speakers the same.Or one amp in stereo for the left speaker and one amp in stereo for the right,but you will need another set of pre-out on your pre-amp and another set of interconnects.Worth the experiment, and there's no shortage of amps for sale used.
I am using the H2o Audio Signature Monoblocks - they were designed to drive the Apogee Scintilla's which drop to under a 1 ohm load. They are currently driving my Martin Logan Summits very nicely now that the speakers are finally breaking in. I am using a pair of the M250SA's.

Hi Pal. I would strongly recommend that you at least audition the NuForce 9.02's. They are only $2500. pr. and I believe they still offer a full 30 day trail period.
I am currently using them to drive my Summits - with incredible results. I have owned numerous amps, from solid state, tube, hybrid and several ICE based amps and none has offered the unique delicacy, effortlessness, dynamics, etc., of the NuForces, while still maintaining the midrange timbre that Logans are capable of.
I have done a fair amount of experimenting with this amp/Logan issue as I have also owned Prodigy's, Oddyseys, Requests, Aerius i's, Sequel II's over the last 20 years.
Another good recommendation is Audiofrankj's H2o amps, which he seems to be having very good results with his Summits also.
Unless you like dealing with the heat output, tube replacement hassles, and larger electric bill of tube amps, the NuForce or possibly the H2o's will give you everything you are looking for, IMO.
I tried the Nuforce but I didn't like the speaker terminals. I biwire with two sets of cables and there is no way to tighten two sets to the amps. I do not like the plastic threads on the posts. I was afraid to tighten them, I thought they might strip. The amps sounded OK, great detail on the top and bottom, but I thought they were lacking some body in the mids. I sold the Nuforce and bought a set of Rowland 201s. The 201s sound excellent. I think I have found the right match for my system.
I am considering a move to the Vantage from the Ascent i. I still hear the hole in the upper bass with the Ascents. My friend has the Summits and they definatly do not lack in the upper bass. I know the Vantage does not have the low bass like the Summit, but does the upper bass blend better than the older MLs?
the integration on the vantage is the best i've heard yet on a logan, it's very good. even tho there is an internal amp for the woofer, the bass takes on the character of the amp you pair it with... with my cary 805c, the bass is full and fleshed out.
now, in comparison to some audio note AN-E's that i heard over the weekend, it does not compare in terms of integration, but in terms of transparency and imaging, the vantage spanks the audio note.
