Audiophiles care not about numbers, they believe that equipment performance cannot be measured properly by any of the standard tests. Instead, the materials and methods of construction are critical. Silicon is often not an acceptabe material. Therefore *any* design that includes a semiconductor "log pot" will be rejected because it includes a semiconductor "log pot". > I do wonder what the HIFI manufatures use??????????????????????? The equipment, even the more expensive models, found in the "hifi" section of general and discount stores is immediately considered "junk" by these people. Actually a potentiometer remotely adjusted by a motor tends to be used in the higher-end versions of the consumer grade stuff. The lower-end ones use analog multipliers controlled by a voltage, which isn't very good by any measure but it is cheap. So know your engineering, but also know your market. _____________________________________________________________________ You don't need to buy Internet access to use free Internet e-mail.
