So I noticed that Pioneer have some MOSFET amps, and since I have a MOSFET headphone amp, I'm pretty happy with its sound, I think I want to go that route. Who else besides Pioneer does MOSFET amps, if anyone? Any opinions on Pioneers? I'll be keeping the stock source and sub, and upgrading the speaker drivers (2-way in front) to Focal two-ways. Not sure which ones yet, prob Polyglass or Access.
