I too have the PL2 and rolled the input tubes per Upscales reccomendation . I like it much better .
While I did not have a problem with the highs , the new input tubes did bring out the bass and warm up the mids .
I did not notice any effect to the highs .
Actually I like the highs on the PL2 , better than some tube amps that roll the highs off . I don't find them strident or over emphasized . Could be a difference in the source and/or cables .
Good luck .
