Pure class A amplifiers = "slow" amplifiers?


Hi folks, I know this is subject of controversy. In general pure class A has been regarded as the best way in solid state amplification to get the purest sound. In my experience many pure class A solid state amplifiers (Accuphase, Pass Labs, Plinius) sound "slow" and are lacking "dynamics". Do they sound that way because they have less distortion than class A/B amplifiers, I mean sometimes a signal is so pure that one is increasing the volume adjustment knob to get a louder sound. With a very pure sound it seems like music goes slower too (= psychoacoustic phenomenon).

Hi Chris,

I notice that you are using Furutech wall outlets (cryoed)...are they the gold version?

In my set up, i used to have the top of the line Gold outlets...they kind of "muddied" the low end which kind of resulted in a slower sound...

When i changed over to Hubbell 5362 (normal and uncroyed), the sound seemed to lighten up.

SO you may want to consider changing one or two of your wall outlets to some other brand to test.

Also, i have found power cords to slow down the sound of a component. For example, when i use a warmer cord (copper) versus silver, on the Pre or the source, the dynamics slowed...

On the amps, i used to use Black Sands Silver Ref Mk5 and they sped up the amps...

What this showed me that if you use warm (cord) and warm (components), things sound richer (maybe quiet) but could slow things down....this is where the synergy thing works i suppose.
