Randyh: That's what I plan to do until I can assemble the "new" components I'm after. I do realize that the Heresy IIIs only require a few watts. What would you consider "overkill" as far as wattage is concerned? I was considering the First Watt F6, but was advised that, though tempting, such low wattage amps are not ideal for daily usage.
buckaroo: Nope, I cannot afford the newer MAC stuff, which is why I'm looking at used, older Mac and Audio Research pre amps - still undecided on the amp, but as I stated the MC250 and 2100 are appealing.
The Marantz PM8005 is supposed to be pretty decent, or so I've read.
