I am using a stock SB3, with a Bolder PS, through the analog outputs, direct to a gainclone amp.
I intend to get the full mods, and intend to use the analog outputs - I sold off a Mensa with Bolder PS, after hearing the stock SB3, but still think I may, at some point..., use the digital output, so I will pony up for the full mods, to allow future flexibility.
