![]() The digital chain is also on the leaner/cleaner side, so most Class D may not be the perfect fit. But more than anything, you’ll want an amplifier that is stable down to 2 Ohm so that it can handle the wilder than typical impedance curves of the ML 11A.Ĭlass D amps could be a good direction to go performance-wise, but tonal balance may be a shocking difference coming from the OP’s CJ amp. There is good advice above from steakster on the Voltage vs Power paradigm. On the flip side, the bass is usually very high impedance, so less capable amplifiers will make the speaker sound muffled or boomy. When an amplifier is not powerful enough to control the speakers, the first thing that goes is detail and clarity. ![]() Most electrostats and planars, including the ML 11A, have very low impedance in the high frequencies. The right choice of amplifier will certainly deliver what the OP is seeking. All my planar speakers required pretty high listening volumes. I have had various electrostatic and ribbon speakers over my life and while they haves strengths, they have many weaknesses. These will give you solid bass and natural presentation at all volume. Secondly,I would recommend looking at dynamic… like Sonus Faber, or DyneAudio. This will put you in a whole different category of speaker regardless of the actual choice. If you were going to do one thing, I would definitely trade in and apply the $10K to new speakers. My system now sounds the best it has at low levels (see my system). The volume at which my systems have sounded good over the last fifty years have continually dropped as my system has gotten better. If you like the character of the sound then I would not recommend switching to a solid state amp. When I had solid state amps more power made a difference in impact… making them sound better at all volumes but they still sounded best in the high 70’s to 80’s. I think the reason it is hard to get an unambiguous answer is the dynamics are not strictly one component and different systems react differently. They have years of first-hand experience in how to make their products sound best. It’s always a good idea to get suggestions from the speaker manufacturer. Zero bass - but an incredibly deep & wide sound stage. Much to my surprise, this set-up sounded amazing. The two speakers were placed just slightly outside of his ears - about 2 ft or so apart - at low volume. Long ago, I visited a Martin Logan owner who used the speakers as giant headphones. Exceptional! He’s got several models that are designed specifically for ESL’s. When I powered them with a 250 watt/ch solid state amp (that doubled-down), it was a night & day improvement.Īt an audio show, the best sounding electrostats I heard were driven by a Sanders Sound Systems Magtech Amp. When I powered my electrostats with 50 watt/channel-push/pull tube monoblocks, they sounded really, really bad - at every volume level. Would a better DAC help in this regard? In short, I am trying to get this right, but its almost like I am operating in a vacuum. My budget would be up to $10,000.00, but I would have to have a home audition before to avoid another mistake. I was thinking a high current amplifier (where power doubles when you drop from 8 ohms to 4 ohms. I know the speaker is a tough load to drive as the impedance drops below 2 ohms. Any amps recommended that will mate well with the Martin Logans and maximize their sound. I have listened at low levels and do not get the dynamics until the volume is turned too high for my ears. I typically listen at 65dbs with 70DB peaks. Is anybody from the school that more power will bring a speaker to life even at low to moderate listening levels. I just purchased the Martin Logans 11A's one year ago and am not looking to get rid of them so quickly, not to mention the financial loss. I realize that a high sensitivity speaker in the mid 90's for example would allow the use of a lower powered amplifier. ![]() My system consists of Martin Logan 11A's, Conrad Johnson Classic 62 (60 watt per channel), Rogue Preamp, Lumin U2 mini streamer, and a Chord Qutest DAC.
