You are absolutely NOT kidding. 23 kHz is the best.

Sounds just like the SoundMeister cards I just got. Wow.
I think it compares to my 16 bit ESS 1868, if not better.

It's actually measurable. I took readings from the ASig pin (3)
on the Ensoniq molar plug to the case of the power supply, and
although it fluctuated 200-300 Hz, it read like 23, 150? to 23,580?
Unreal. I have a couple small samples I took straight over, and they
need to run at 11 kHz for the speed, and they sound like garbage.
Overall, it's great sound though. I have to try the GoldWave MP3
to WAV convert tomorrow and see how that goes. Kool.
