Yup; My Marsh A400s' led is blinking with the MMG's at high volume. Those panels do dig low.

Oh well, I don't usually listen at those levels (measured at 96 db), so not that big of an issue.

But for some reason I am regretting having sold the Belles.

    My Adcom's blink a little when I go nuts. The indicators just show when the distortion is getting up there. If it is pretty solid on the lights then you may be clipping, but I have never gone that far. I see a few blinks and I do not go any higher. Are the Marsh amps the same as far as the LEDs?

    That's the problems with those type of speakers and ribbon speakers, they can drop pretty low. No worries thou, Ricardo knows what to do. (Buy different speakers)
    LOL

    I'm sorry I could not resist.

    I would assume the blinking means it is getting up there, but I have no literature on that.

    When I had the 1.2's and the GFA-555 those lights loved to blink.

    Different speakers? Yes, probably a pair of Maggies 1.6 :eek:

    Blinking hard or steady is about 3% distortion. Subtle blinking is about 1% distortion. With Adcom the lights flicker quite a bit before any damage can be done..........generally speaking.

    As I remember you had your Belles 350a upgraded to reference by David Belles, correct?
    I had a conversation with David a few weeks ago and he told me it's now $1,500 to do the upgrade. Not a direction I will go at $1,500. thats for sure. I will say the 350a is a really nice amp. At every level of volume the sound quality is awesome. I've never enjoyed listening at lower volume levels till now. Oh well good luck.

    mmg's, those are the smaller mag's,correct? very suprized the 400 would go into clipping. i know you probably would consider it a down grade, but a parasound 3500 would blow the mmg back to the factory if you try cranking the thing up. and to tell the truth,it wouldent sound bad at all.

    Not familiar with the equipment, and if a lot of bass is present it can take a good amount of power, but 96db, while certainly loud, is not that high.

    More to the point, does the amp do a good job of preventing damage to either itself or the speakers? I suppose it is from the lackadaisical tone of your post.

    I've witnessed Ricardo's predicament. I'm surprised that the SPLs were that high. Seemed like the amp "blinked" quicker than that, but it could have been the disc I was demoing.

    Still sounded sweet in conjunction with the MicroPro sub.

    Ricardo, did you ever cross the MMGs? I wonder if they were crossed at 100-120hz if that'd help the dips??

    Good job Ricardo.......you finally got a 'real' amp :p;) . You are going to **** your flat hat when you get this up and running!

    The difference between the Aleph 30 and the Marsh A200s I used for awhile was very apparent. I assume the similar for your situation and may even be greater. Plus, if it just doesn't play well or you don't like it you'll get all your money back if you have to flip it.

    Looking forward to an honest review from you. Congrats!!!

    My understanding is that while the impedance of some Maggies can be on the low side ,the impedance does not vary with frequency as much as with a system using regular drivers like say the LSi9.


    RT1-- Hint .......how many ampers can be delivered into say a 50k load?
    Im betting a few miliamps would suffice.

    Unless RT1 uses a different Ohm's Law for tube amps and 50K ohms load. :D
