DVD player with high HiFi quality
I was considering buying a new Hi-Fi system (Marantz PM6004 and CD6004) and realised that I have a few music DVDs that I'd like to listen to / watch as well. I'm thus wondering if someone can advice a good DVD player with high-quality Hi-Fi (marantz or other brand). I don't watch many movies so I'm mainly interesting in something that can restitute music as good as a possible. Or, is that definitely better to buy separate elements?
Also, with this settings, does it make sense to stick with the PM6004 os is that better to go for a AV amplifier? Considering that I won't need 5:1, etc., and most of all am looking for a sound quality before the rest - and so want to stay < 500£ for in the amp.
