Diferences betwwen SVI and RSN chips

What are the diferences between Panasonic(Technics) SVI and RSN chips?

Nobody know...??

Technics Amps...

mmmm

the old SVI series was based on a higher current handling hybrid IC
such series were SVI200* SVI210* pure output stages w/ overload det.

then they has SVI310* and SVI320* series, these ICS had full onboard operation, had pre amp ic and protect ic inbuilt which prevented overload, DC offset whilst providing thump/dethump prot,

then you had SVI400* series, custom built w/ extra emitter resistors to form the class AA bridge - similar internal layout with different input stage

then Technics got cheap - they skimped out on their heatsinks
then the power hybrid ics themselves hence the RSN series/ i believe the series changeover is due to having the ics developed by a different manufacturing plant or Matsushita knew that the ics werent going to be like the old school SVIs

moreso the big introduction w/ this IC was the class H operation, where its more suited to home cinema use rather than the sheer sound brilliance of the older SVI series (mainly the SVI2 series)

some models are pin compatible, i will add more to this when i explore more RSN ics, - i only own 1 amp w/ these RSN chips, that being a SA-TX50 Pro Logic/THX amp n only then used as the pre amp

i hope this gives you some insight to this

Ok!
Thanks!
