for 98dB sensitivity, the PL non-HP would be more appropriate.
It really is an amp "for life" if you want it to be. I think the PL is an awesome "blueprint" of an amp to build on and play with for years.
I'm not a big "tube-roller", but changing out the stock tubes for some carefully selected KT88s and 12Au7s has absolutely pinpointed the best sound for my speakers and room. that is the beauty for me. I can change speakers, but the PL will still drive them well.
