Anything as " fast" as SPECTRAL gear?

So Al, what does that mean in the context of ARC ref amps. As I mentioned above, the slew rate for my amp (150 wpc) is a paltry 13 volts/microsecond and the rise time is a sluggish 2 microseconds. The top of the line Ref 750 has a slew rate of 20 volts/microsecond and a rise time of 1.5 microseconds.

Based on your comments, I gather a CD will be over before the amp is able to get a signal to the speakers. Almost like playing a 45 rpm record at 33 rpm on a turntable. :)

Of course, I'm being tongue in cheek, but I gather there is some overkill in the specs. Kinda like an amp with a DF of 1000 ... way overkill. Ralph has mentioned that a DF over 20 is a waste.

Please clarify.

Bruce (Bifwynne), a basic point in my analysis was to show that even relative to VERY conservatively drawn thresholds the speed-related parameters of the Spectral amps are **in themselves** extreme overkill. While at the same time citing the possibility that the overkill might provide indirect benefits in the design.

The numbers you cited for your ARC amp don't seem to me to be unreasonable in any way, they just represent a different philosophy and a different approach, which result in less margin (but arguably still very reasonable margin) in those particular parameters.

Mapman, re your question, I'm not really sure. I too believe that there is a strong relation between resolution and holography/dimensionality etc., but my instinct is that linearity, distortion, and noise performance more often than not tend to affect resolution more significantly than the speed-related parameters. Just MHO.

Al, makes sense. Thanks.

Al; where the heck did you get this knowledge?

I'm an EE with extensive analog and digital design experience (for defense electronics, not for audio), and I've been an audiophile for about 35 years. Audio has always been of interest to me from a technical standpoint as well as a musical standpoint.
