Does slew rate matter?

24.4.254.165

Your statement makes sense, but once upon a time so did the assertion that a 44.1 kHz sampling rate would accurately replicate signals up to 22 kHz. Why does a higher sampling rate sound better to me, when I can't even hear 22 kHz? Okay maybe this is apples and oranges, but it seems to me sampling rate is in some ways analogous to slew rate.

Now that I have an upsampling DAC I hear a greater difference between amps, specifically on piano and cymbals. Over the past two weeks I have experimented with six different amps - solid state high power, solid state low power Class A, single-ended 845 triode, and three OTL tube amps. I hear a greater nuance and sweetness in both the crash and shimmer of cymbals, as well as the impact (yes, impact) of piano, with the high slew rate OTL gear. Is this cause and effect? I don't know, but for now I believe so.
