Most equalizers do not have sufficient control to correct the problems Bob mentioned -- their response bands are too broad, at fixed frequency and Q, affect phase, and consequently induce new distortions for every one they correct. He has an interesting thesis, and some evidence to back it up. I'm still waiting for a properly controlled, statistically significant study which shows that people can hear the difference between amps even without identical frequency response as measured at the speaker terminals -- anybody out there have a reference for me?

The digital cassette looks larger than the standard cassette from what I could tell. There was an interview with a Phillips spokesman from the winter CES on CNN the other night. The DCC (digital compact cassette) does NOT use a case. It is a complete unit, and the artwork, etc are printed on it. The spindle holes do not go through the cassettes. (not needed as it doesn't turn over). >From seeing the video of the cassette, I got the impression (it may be a wrong impression) that the unit will play both, but that the cassettes are not the same size. Sort of like the VHS players that will take a C size vhs cassette without an adaptor. They said 18 months before it's on the market. As to moving to the same media and being interchangeable, the current DAT is 4 mm. The DCC is about that width (not sure of exact specs.) There is no reason to have interchangeable media until the video goes from analog to digital. Otherwise you are putting more expensive media in a video than you need. -- Bill Vermillion - UUCP: uunet!tarpit!bilver!bill : bill@bilver.UUCP

Bob Carver has just sent in a follow up column to his last one that I posted here recently. It will be appearing in the Vol. 2, #1 issue of POSITIVE FEEDBACK shortly. I'll post it here on rah-e via tjk within the next week or so. BTW: Pacific NW audiophiles: The Oregon Triode Society is having its "first annual swap meet" (optimist!) here in Portland on Friday night, February 1, starting at 7:30 p.m. The site is: Portland Christian High School 12456 N.E. Brazee Portland, OR Call me at 503-235-4356 (evenings) for more details, if you'd like to attend, or rent a table for a display ($5.00/table). Sorry for the abrupt change of subject...this just looked like a good opportunity to post the announcement! ;-) david@agora.rain.com -- My opinions belong to me...and vice versa.
