I am afraid I have to agree that those components are priced high compared to what we can find in the US.
The later Pioneer are not as 'special' as the early/mid 70s units...
Think wood cabinets and etched metal faceplates.
The later amps have the flashy blue meters and nice specs, but the guts don't compare.
For 600 euros one can get some mighty nice new kit!
These are not "later" Pioneers. The flouroscan meters were added to the SA series around 1978. The progression in the US was SA-5500, SA-5500ii, SA-5800. The amp pictured in the ad is an SA-5800.
