musical fidelity m6s prx amplifier with SDA SRS

Does anyone have any experience with the musical fidelity m6s prx amplifier and SDA SRS speakers. I’m looking at getting a new 2 channel amp for a dedicated 2 channel system. I’m not sure if they are common ground.

The m6s prx fits in my budget right now. It sounds good in the store, but I have no way of testing them with the SDA SRS 2.3’s.

    It, like most MF amps, is true dual mono and therefore not common ground.

    Time to build a Dreadnought.

    Thanks for the input. I thought when we measured continuity and got a continuous circuit it would have been a common ground. But I was confused when I looked at the front of the amp and it said dual mono. I’ll have to look into the Dreadnought and what it requires to make one or look into a different amp.

    Where did you measure and what reading did you get?

    I’ll have to ask him where he measured it, The back was not facing me when he used the multimeter on it. It buzzed for continuity and I thought I saw .3 ohms when he switched it, but I don’t know what scale he had on it or where he was measuring. I’m not sure when I can get back there to remeasure the amp. Where should the measurement be taken from?

    The negative binding posts.

    You can always ask MF.

    Looks very dual mono.

    I asked the sales person I am dealing with to confirm with the manufacturer on wether the amp is common ground or not. Since he is on vacation this week I am expecting an answer early next week. I also asked about the measurement and it was taken at the negative binding posts to the speakers.

    Thanks for the input. I really appreciate it.

    This is what the manufacturer said. I had also asked about the power into 4 OHMS and wether it has an inverted channel like the carver amp I have that won’t work properly with the SDA’s.

    Musical Fidelity says: According to our test results, at 4 Ohms the amp delivers 370W (continuous, at ≤1% THD/1kHz), both channels driven.

    The amp is a common ground design, the speaker (-) output is connected to GND. Therefore no inverted channel


    Based on this I think it will be OK for SDA SRS 2.3’s. Am I missing anything here that I don’t ask?

    Thanks for that info. So, not what I thought. Sorry about that.

    I appreciate the input. Better safe than sorry. I’ll probably get it in a few weeks, but I have to demo it first at the shop and make sure I like the sound. I’ll probably have them demo it with L600’s in case it doesn’t work out with the SDA’s I can use it in the home theater setup.

    If you don't like it I'd be surprised. I've never heard a piece of MF gear that I didn't like.
