Can't say that I blame you. In the Tone Audio review of the Rega, the reviewer found the Brio much more resolving than other competitive integrated amps, but I'm pretty sure he hasn't auditioned the PM8004. I suspect that Mapleshade's modded Scotts would satisfy your tube jones while providing more resolution (better clarity, definition, and dynamic subtlety and punch) than a current budget tube amp. For dead nuts neutrality. low noise, wide bandwidth, flexibility, control over a wide variety of speakers, and unfailing musicality,the Marantz is special though.
