I am looking to build an amp for home theatre/hifi use.
currently have an amp using Hitachi's default design for mos fets from the
'80's ( 2sk49 2sj50 I think ). It is used with a tagmclaren av32r and ipl
acoustics tl4 speakers at the front and Ariston ( small black tubular things
that sound quite good ) at the back.

I plan using LM4702 but have three options for the output stage.

bipolar
SAP15P and SAP15N
2SA1943 and 2SC5200
mosfet
2SK1530 and 2SJ201

I know I'm inviting WW3 but would there be any differance in sound between
them ?
