Hi there, new guy here, I've had a Panasonic RX-DS45 for a long time since I was a teenager and I find it very practical besides having some nostalgia factor.
Anyways, as you, I sometimes wonder around checking some older models and stuff and noticed that the European version of the RX-DS45 has a few differences. First off it doesn't seem to have metal/CrO2 capability. Second it doesn't have dolby nr. Third it has XBR instead of the S-XBS present in the Japanese and American versions. There are some minor differences in the display too. Checking around some older models and catalogs it seems that XBS system later evolved into S-XBS. Was this just a marketing gimmick or is there any effective difference between both, like the frequencies involved ?
Another interesting fact I've noticed is that the service manual for the European version of the RX-DS45 mentions SXBS in a certain part of the circuit. Maybe this manual used the Japanese/American ones as templates and there are some left overs but it begs the question, is it just the name ?
Cheers to all and great site :)
