    Geof, I may do that someday. But for now, the Maggies had to go. My friend (who I borrowed them from) needed some fast cash for x-mas so he put them up for sale. I helped him pack the speakers, too. He gave me back my Meadowlarks, so I didn't mind at all - much easier to drive & place in the room.

    So for now my foray into the world of Magnepan has ended. I may be getting a pair of Vienna speakers to play with soon, and I've been told they are a handful to drive as well, so we'll see. Thanks for the help with the Maggies. I'll certainly be back if I can get my hands on one of the bigger Maggies.

    I use the Emotiva XPA-2 with my Maggies MMGs with terrific effect. Has great control, tight bass, good midrange, just woke up the Maggies. Best amplfier for Maggies in the bargain price and more range I think. I noticed that someone mentioned the A23 Parasound, I would actually use the A21 instead, pricey sure but the extra power is worth it.

    Are the MMG's you're talking about the same ones you said in a different thread were not working right? If so that could explain the lifeless sound you were experiencing.

    Yes, those were the ones, so I'm still open to planars, but the size thing is a whole other problem for me.

    Just curious, how can you be disappointed in the sound when you knew they were broken?

    When I owned a pair of now-discontinued MGLR1 planars, I drove them with a Carver TFM-35x (350Wpc @ 4 ohms), and a classic McIntosh MC7200 (300Wpc @ 4 ohms) with excellent results! Although I'm into low powered tube amps and efficient horns at the moment, I still love that planar transparancy and detail that Maggies provide. I have no experience with the entry-level MMGs, but I assume the MGLR1s were only a slight improvement at $900 a pair, and they sounded fabulous IMO with classic rock and pipe organ recordings in my 12' x 13.5' room. I'd love to check out Magnepan's MG12s and MG1.6s when finances allow.

    Amps with these modules can be found relatively cheaply. They are small, cool, and extremely efficient. Perfect in every way.

    Correct me if I'm wrong, but you're using Class-D amplification modules to drive your Maggies? Or are you using amps from other manufacturers that use the ICEpower power modules installed?

    After briefly viewing ICEpower's website, I get the impression they provide other amp manufacturers with their modules. Or do you purchase the modules direct yourself and build a chassis to house them? Where can I find info on amp manufacturers that use these ICEpower modules?:confused5:

    Thanks in advance for any info you can provide.

    Looks like someone revived this thread, so I'll join in. I now have MG12s in my 2-channel system and MC1s, MGWs, and an MGCW in my HT setup. I drive the MG12s with the Spectron amp and the HT with a Rotel RMB-1077 slimline little guy.

    Frankly, the Rotel leaves a lot to be desired but it's small, sleek, and runs reasonably cool (although nothing like the Spectron). My biggest gripe is that it exhibits all the expected behavior of class-d amps: so-so midrange and not much up top. I previously had a PS Audio multi-channel monster in its place, and that was a whole different story, but now I'm slumming it with the Rotel.

    The MG12s with the Spectron are an order of magnitude better than the HT setup. That said, I have an itch to go a step further on the 2-channel system and try bi-amping with a pair of tube monos for the treble and keeping the Spectron on the bass. It's just a thought at this time, but it sounds intriguing. I'm not saying the Spectron is lacking in the treble (at least certainly not like the Rotel), but I just want to see what I may be missing there.

    dont exhibit the maladies you ascribe to class d amps. and as you know the spectron is d class as well (from the inventor). my friend had the cia d200s driving the mg12s to great effect plus von schweickert himself demoed his $50k speaker system with them which mightily impressed ME.

    using the spectron on only the bass tells me that you have too much expendable cash. i'll swap you my adcom 555II for it. heheheheheh!

    Well it's not like I have a dozen fancy-schmancy HT rooms to choose from every day, like some people here. Fact is, I typically have to sell stuff to be able to afford something new, and this x-mas season I did pretty well. So I do have some extra cash to spend, but then again, I still have to get through tax season...argh!

    Regarding Channel Islands, I've actually visited the manufacturer and took a considerable interest in the mono amps a few years ago, but my experience with them was not that stellar (certainly not what Stereophile's reviewers heard). The mids and treble, while certainly respectable were still a bit subdued and they lacked a bit of air and separation. So far, only the higher end stuff from PS Audio and the Spectron amps have impressed me. Still haven't had a chance putting a good pair of Bel Cantos through their paces, and on the class-d front, that's probably where I'd look next. Channel Islands amps are very good, don't get me wrong, but I have to defer to what John Ulrick never tires of saying: class-d amps are not all the same and they are incredibly hard to do right.

    Another point Ulrick makes is that class-d amps require much more power to compete with regular solid state amps, and while I don't exactly understand why, I have to agree that power does make a difference to my ears. The 100W or less class-d amps just seem to lack more than their big power siblings. For some reason it affects the whole sound, even on more sensitive speakers than planars. Maybe someone can chime in and explain this? Getting back to Channel Islands, I only tried their little 100/200w amps, so that may be a factor as to why I didn't like them so much - it was also some time ago, so maybe things have changed a bit since?

    FWIW, I am using 2 Halo A21s in a passive bi-amp config (soon to go active). THose amps are excellent with the mags...as was my Pass X-150.

    And I can tell you that the Velodyne Optimum 10 is a fantastic match at least if you have a pair of them. Frickin tight fast bass that blends with the mags.
