Hi everyone,

I am contemplating between obtaining a secondhand Torii Mk4 and a Pass Labs X-150 and was wondering if anyone had experience with these amps and could provide input. The SE85UFO25 would also be a consideration, but I think it will be slightly out of my budget range.

The rest of my current system consists of a Schiit Gungnir Multibit, a Woo Audio WA-6SE that I am using as a preamp, and Klipsch  Heresy HBRs with ALK Engineering tweeters. I am currently using a '50s Magnavox 165 stereo console power amp that I restored (quad 6V6 PP amp) but IMO, I am lacking transparency and imaging as well as slam (though I understand my Klipsch speakers have rather subdued low frequency extension).

I am currently in an apartment, so not an huge room, and I don't listen at extreme volume levels. I listen to mostly classic rock, jazz, and electronic.

Which amp of the above would you choose?

Thanks!
