I have narrowed my choice to these three receivers. Perhaps this has been discussed before but how do others feel regarding the following: a) is the 4802 "worth" approx. $1,000 more than the 3802? b) how "valuable/important" might these features of the Sherwood be (which is priced online somewhat lower than the 4802--aprox. $200) 24/192 DAC all channels and the ability to upconvert all PCM to 192KZ? Thanks for any info. on these questions and any further comments on the various pros/cons of the 3.
