You too. Greek food has taken a back seat here in recent times, I found a very interesting restaurant in SF that I can't wait to try.

But if you are ever on the Island of Kauai in Princeville do try the Bison, better than any steak you'll have.
I do love the grass fed beef in Waimea on the big island. I have not been to Kauai since my honeymoon in 1985.

Hare is an aquired taste if it is truely wild served up in its own blood, civet de livre in French, IIRC hassen in German.

Kgrlee,
If you are only doing a test to determine if a group of people can hear a difference in multiple sources I have no problem with that as being a legitimate test condition. But when you are testing to see if you need to band limit the frequency response so people would prefer that band limitation then I have a major problem with that test. Unless the speakers that are being used for the test are completely accurate and have no resonant problems in the upper frequencies I would called that a flawed or biased test method. It would be way to easy to get the result that you want in that test. I could use many metal dome tweeters and come to the same conclusion, but that is a very poor test indeed.

Scott,
Your avatar lists Cambridge, but you are talking S.F. Are you on the Left or the Right coast?

The "fussiness" component is crucial in audio: if you ignore it, or dismiss it as not being particularly relevant then you will most likely never hit the heights that are possible ...

This was just an excuse to wish all who are about to supposedly fall from a great height, Happy New Year ! -- 2012 is done and dusted down here ...

Right now both, shifty guy.

I think you are all looking down the wrong path to understan audio perception. The Lossy codec guys have done an enormous amount of work in understanding our hearing and have been very suvvessful. Ignoring there understanding is I think naive. We may want to exploit the knowledge differently but the basics of what they have leared could contributes to what we want to accomplish.

I sat through a lecture at Dolbylabs on how they test codecs. It was remarkably rigorous and effective. Its much easier to program tests for codecs that for speakers but the principles are similar, just no mechanicals needed. They even have serious analysis software to verify results.

A lot of what seems important there assaults our basic principles, however when banging your head against such issues as whether phase above 10 KHz matters, a better understanding of the tricks used may yield some insights. My understanding is that even pitch is less important, just the energy and its timing. Given that the waveform changes with distance this could make sense.

My intention was much more humble.

I hope the results of my tests would be of use to the majority of listeners. Some would have speakers with good supersonic performance and some not.

You can consider the test similar to "should you change all your resistors to ones hand carved by virgins out of solid Unobtainium and recommended by our Lord JC."

The difference is that the test is double blind bla bla ...

ie does this evil component (the brickwall filter) actually make YOUR system sound better?

Of course if you conduct or know of such a test and find a different result from what I, and other people, have found please tell us.

I leave it to other gurus to ..
  • explain why (ie produce theories that fit the evidence)
  • or explain why it can't possibly happen (produce theories that don't fit the evidence)

The 1980 (?) test was with speakers with 30kHz response as measured by a 1/4" B&K mike. The treble unit was a 19mm 'soft' dome from a material that is now sadly Unobtainium.
