Very cool article. Fresh from the internet printing presses. It will be interesting to see how and what this technology will change within the audio world as time passes.

    It does save some time. Maybe PMC will produce some better sounding speakers because of it. :D

    These things can be measured with a traditional microphone, but it's much more time consuming.

    These are the kind of graphs they're achieving in a much shorter time.

    ...and if we speed up the learning curve, we [theoretically] speed up the technology, no? Baby steps lead men into walking. Sonically speaking, I feel as if we are at the crawling stage. Albeit a damned fine crawling stage but we still IMO have a long way to go.

    too bad the technology is being squeezed out of audio, the markrters and accountants are winning.

    It's not being squeezed out at all.

    You are welcome. Imagine having a CDP and a pre.....completely off the grid and powered solely by these. They could charge in between the songs, when no signal is present or while you are changing albums. Only the amps would need to be on the grid for a super quiet noise floor.

    ♪ Imagine all the people ♪

    Imagine making it able to take a solar charge Now that would be AWESOME..
    Could be a unlimited power source depending on how long the Graphite battery would last..

    Even with solar recharging, batteries and cold weather don't get along too well. Winter effects more than half of the country. Has me thinking now of how Nasa overcomes the cold of space with their batteries. Solar recharging is nothing new obviously but circuits are designed for minimal draw on a space station or shuttle. Cars need lots of power for such a small vehicle and solar recharging as is now takes too darn long.

    Been trying to tell folks about PMC for years. They are the British equivalent to Sandy Gross etc. Only difference is Sandy has managed to reproduce 99++% of the sound coming out of a PMC EB1 for 1/3 the price in his Triton2's. I have the surround speakers and they are F$$ki!!!!! incredible. You know sound is coming from a center area and surround areas but by no means can you localize the source to the speaker location. Remarkable. Like saying speaker left and right v. stage left and right.

    I'd easily take any LSiM speaker over anything PMC makes. I'm not familiar with their surrounds, but have heard a few of their tower speakers and they're OK.
