    that sounds extremely interesting Ted! and like a phenomenal design challenge too!

    Ted, I’m looking to have a play with these class-T amps (I’m rather behind on this technology) but Tripath were bought by Cirrus, of course. Can I ask you what supplier you have had good results with? I have someone asking me about making some battery amps, and they might be just the job.

    thanks!

    well, regardless of the amplifier story – having better live sound at acoustic concerts would be absolutely fantastic! It is one the banes of my life, as a musician AND and as a listener! So many times this has been a huge frustration.

    I wonder if this technology of yours would scale to PA applications, Ted? I was at a small festival the other day watching an acoustic jazz group. They had the usual arrangement with a couple of speakers either side of the stage, and as usual, the sound was OK near the sound man, but quite poor off axis. Acoustic bass suffers most, I guess because of phasing issues between the two sides.

    Amplifying small acoustic groups in open air seems to be about the worst case scenario of sound reinforcement, and I don’t think I’ve ever heard it sound good. So much so that people pretty much seem to expect it to be bad. I wonder if using a single sound source would help significantly.

    I am very curious about those speakers – i am going to see if I can find somewhere round here to listen to one. Yet another original and interesting idea!

    This is a very interesting idea. It makes total sense to control the current in the speaker of course – I know the idea has been around a while but this is the first I heard of someone actually making it work.

    Out of curiosity- how high the voltages get at the amp output? I guess it depends to some degree on the speaker, so the amp and drive unit come as some kind of “matched pair”?

    The different waveforms that would appear at the amp output are probably interesting too, as I guess they tell you quite a bit about what the speaker impedance is doing in real time?

    :( It’s just amazing what you have achieved over the years Ted!

    Ted, this is fascinating information and thank you for sharing it!

    I’ve been playing around with the design of an optical compressor of late (something I have been curious about for some years, since I first designed more mundane ones around SSM2120’s some years ago) – after a few months I think I have something that sounds pretty good. I was quite proud of myself for figuring out what I though was a fairly novel topology – then I did some googling, found some Joe Meek schematics online and discovered … well … nothing new under the sun! You were at least 20 years ahead of me :-) Oh well, I guess what sounds good just … sounds good.

    Anyway – thanks for being so generous with your knowledge and expertise!
