CAL Audio Alpha DAC

Fpeel, That's what I thougt. I own a Delta and used to own a Alpha until I sold it here in favor of a dCS Delius. The CAL Delta/Alpha combo is a classic. Best of luck, Dan

It is the filter that is used for 24/96 sampling that makes the biggest difference in the sound of standard cd discs and played with standard cd transports.(A 24/96 transport is necessary for 24/96 discs.)Full description in the editorial of the Sept. 98 Fi magazine.More space, treble, definition and resolution.Many are happy with the Cal upgrade and much of this can be accessed in the audio asylum search section.

Thanks for the lead, Lihifiguy. Hadn't thought to look there. Most interesting thing was the complete lack of any negative comments about this upgrade. People are generally more apt to post complaints than compliments, so that says a lot about the improvement it brings. Looks like another item is going to be added to the wish list.
