That sounds like overkill to me.  Based on research papers that I've read,
and my own ears, 24/96 conversion doesn't sound any better than 24/44.1
conversion.  Higher sampling rates only seem to matter when mixing or
altering sounds within the digital realm itself.  Regardless, I'd take the
Pepsi challenge with my 18/48 PCM-80 against any of these consumer 24/96
delays any day of the week.

This is true.  There are many 16-bit converters that sound better than
24-bit converters.  While there is a noticeable difference between 16-bit
and 20-bit, the difference between 20-bit and 24-bit seems insignificant.

I believe this is how the Korg SDD-2000 works, but it doesn't have voltage
control.

>But what about voltage control?

I have five digital delays, and four of them have voltage control.  It's a
very common feature.

However, none of them can pass DC, which is what I would want in an motm
digital delay module.

Could I get a sample of that sound?? :)
