Suddenly slew rate made no sonic difference, except to the vinylist. Now with SACD and upsampling DAC's available and becoming more affordable, slew rate is going to matter again."
Uh, why?
At 48kHz (the high frequency limit of 96kHz sampling), if you were to swing it +/- 60 volts (or the equivalent of about 225 watts RMS into an 8 ohm load) its maximum rate of change would be a little over 12 volts per microsecond. Of course this scenario would never exist in any realworld home audio system. Under realworld conditions, anything anywhere near 48kHz would be so low in level I doubt you'd have anything with a rate of change greater than a volt per microsecond at typical power levels. So most any amplifier with a slew rate of a few volts per microsecond wouldn't be in any danger of slew rate limiting even with the increased bandwidth of the new formats.
