Are you the first HK ppl to use Luxman 507u at Hong Kong? Congratulation!
It's hard to say to the universal players which you will pick are not good for music.
As you know, the purpose of a AV player is used to produce the accurate sound stage and effect (NO MSG) in 5 channels or more. However, a pure CD/SACD player is totally different picture. The pure CD/SACD player uses 2 channels to produce sound stage and may add lots of MSG in it.
So, do you think that a universal player can do it both?
