President's Message
May 2008

1.  The complete catalog of the works of C.P.E. Bach has been worked on for several years and is scheduled for completion in 2014.

2.  Recently I was given 4 pieces of studio gear including a Wadia Pro analog to digital converter. It was intermittent, but I was able to fix it. I was interested in testing it because I had the impression that Wadia made very professional products...up to a point, then took a deranged turn for some audiophile tweaky reason. My tests showed low noise, vanishingly low distortion and very flat frequency response. I then did a full amplitude frequency sweep starting at low frequencies. All was well until I reached 15 kHz and thee were some spurious tones. As I continued up, the tones disappeared and a hashy noise floor came up. Above 38 kHz it was silent. My Flying Cow A to D had none of that behavior. Apparently they left off the anti-aliasing (low pass) filter at the input, presumably to eliminate the "distortion" from the phase shift of a steep filter. However that phase shift has been shown to be inaudible. I sold it on eBay.

3.  For Boston locals: About a year ago David Griesinger loaned his Soundfield Mk4 microphone to someone who desperately wanted it for a project. He would like to get it back to use for hall measurements in a project of his own. If you have it, please contact me, so we can arrange its return to Griesinger. Thanks. David J. Weinberg, Editor, "The BAS Speaker"

4.  eBay continues to put the sqeeze on merchants. About a year ago they made it mandatory for sellers to take Paypal. Now they are experimenting (in Australia) with making Paypal mandatory for buyers. They already get a listing fee and a selling fee. With Paypal they get a percentage on the money transfer. Up until now you could take a check and avoid the last fee. Perhaps it's time to consider other venues. For audio equipment I find Audiogon, AudioxSell and Craigslist. Has anyone had experience with these or others?

5.  For BAS members out of town we have a special offer for Jazz lovers. A package of 30 Jazz CDs, randomly picked from Ira Leonard's collection, for $22 including shipping in the USA. To order, send a check, made out to "Boston Audio Society", to David Hadaway, POB 460, Rindge NH 03461. These were donated to the Society by Ira's brother, Joe Leonard.
