dvd player plus d/a/c OR dedicated cd


i currently have a nice ht set up that i use for mostly music. due
to space constraints, i have to use this set up for both music
and ht.
-nad t751 receiver
-monitor audio bronze speakers
-denon dvm-1800 5 disc dvd player

from what i understand, dvd players are not the best for music
playback so i am considering adjusting my set-up. here are my
options:
-keep the dvm-1800 and shut up!!!....... cost $0.00

-keep the denon and add a seperate outboard dac processor to
the denon for music playback. i have seen rave reviews for some
really nice inexpensive dacs like the adcom gda-600 that could
be had for around $200-250.........cost $200-250

-sell denon and pick up the nad 515 multi disc cd changer(only
cd player under $2000 to make the stereophile product of the
year) and a cheaper single disc dvd player for movies
(recommendations????).................cost $200

multi-disc capability is important to me.
of course, i will listen before buying but i am
interested in hearing what you have to say.

thanks for the advice. unfortunately, that player is $3000 and only a single disc unit. im sure it performs wonderfully but it is way out of my price range.
i think to make a real jump in sound quality you will need to spend some money. had the 515; upgraded to cal 15...night and day difference. i have heard the old rega is good and arround 400$ cals are in the 800$ range. do not know that you would gain a great deal of sound quality due to other componets. please do not take this as a negative. i still have an nad 3020 in another system. just do not want you to think a great dac or cd player will make all the difference. it a step by step process or addiction. good luck.
that makes sense. what would you recommend as a first step in the process of improving music.
