hi bill,
i have an almarro a205a mkll, modded w/hovland musicaps.  a truly extraordinary amp, imo, hard to beat at any price, assuming, of course, that you have speakers efficient enuff to work w/5wpc.  detail, dynamics, soundstage, smoothness - this amp really excels.  of course, it helps that, in my rig, it's actively crossed over to subs at 80hz!   

   i am curious about the volume pot upgrade - is this something you could send someone for self-install?  cost for the pot?  and, if you run the stock pot wide-open, will you really be gaining any advantage w/swapping out the pot?
thanks...
