I believe it's a fair exchange, they're both excellent 3-piecers. As for which box is better, it all boils down to personal taste, features wanted, and the technical & cosmetic conditions of the units. According to my experience, the Party Center 2000 is better in terms of quality of sound: it's Hi-Fi, it's loud and has gorgeous dynamic bass. But the Panasonic sounds fantastic too & it's possibly even louder. It has the late 80s-early 90s elegance, whereas the Grunding the late 70s/early 80s typical aluminium & chrome finishes. The Panasonic has a lot of extras including a CD (but not a line-in); the Grundig has no CD but it's endowed with a line-in. So now you know more, but you're still on your own...
Nice, does it all work? The tape deck gear often breaks. The Panasonic has warmer bass at low volumes IMO
The tape deck it doesn't work. But i don't listen cassettes. The Panasonic sounds great, and i think the Grundig wouldn't convince me. L.E.: has the Grundig better bass then the Panny?
