I eventually did purchase a new Stage II STP-SE preamp from W4S. I am currently breaking in this unit. It takes about 300 hours and I am not there yet. My initial impression is that the imaging may be a bit more precise and that there is better high frequency extension and detail. I did not hear much of a solid state character from either unit. Preliminary impression is that the factory Stage II unit is better, likely due to the use of the naked Vishay resistors.
Wyred 4 Sound STP-SE Parts Connection vs. Factory Level II Mods
Underwood Wally initially offered Level I and Level II mods to the STP-SE preamp, designed and performed by Chris Johnson at the Parts Connection. Wyred 4 Sound subsequently offered their own Level I and Level II mods. Looking at the description of these modifications they are almost totally different. Has anyone had a chance to compare STP-SE preamps with these different modifications?
