Jmorey, I finally compared the 2 amps, one stock and one modified.
The modified amp is less edgy/grainy/gritty sounding when reproducing the sounds of instruments with a lot of high-frequency harmonics, such as massed violins. Also, the modded amp retains spacial and instrumental decay better/longer, so I expect the soundstage will be larger in stereo. Definitely an improvement, even to this tin-eared audiofool.
Have finally found some suitable high-voltage caps--ASC oil-filled 'propylenes from Michael Percy--to replace half of the PS 'lytics with. (Have already replaced all the 'lytic decouplers with composite 'propylenes.)
