Here's the deal... I just picked up an Alembic F-1X preamp and love the thing. Pending the arrival of a Crest CA9 I bought on Ebay, I had simply been plugging the F-1X into the effects return of my SWR SM900 amp, which sounded plenty good. When I hooked it up to the CA9, I found that I was getting some fearsome distortion on certain transient peaks. I initially thought that the problem was in one side of the amplifer, but after I was able to make both sides of the amp do this, I began to suspect that the amp might not be the problem. I had the F-1X's volume on 6... which worked fine with the SWR... anyway, I turned back to the volume to 4 and have had no further problems with the distortion through either side of the CA9. So... is it reasonable that I might have to be careful to never turn the Alembic up past 4 (and risk destroying my two Whappo Jr.s if I do?) or does this just not seem right? Thanks for any input.
