CDP with volume and digital input...Which one?


I am currently searching for this kind of CDP.I've narrowed down to few:

1.Wadia 861 SE, 581, 850 or 860.
2.Resolution Audio Opus 21+GNSC mods
3.DcS P8i
4.One not in this group, but also considered is Njoe Tjoeb 4000+all upgrades.
5.Cambridge Audio 840C (no volume is a minus)
6.Mark Levinson 390S

I have very big and sensitive speakers, full range(Silverline Sinfonia).Also 320B XLS SET monos (15 W/ch).CDP will be connected directly to 320B XLS power amps.
I need dynamics, punch, great bass and a lot of it,also smooth but extended top end and natural midrange...
Listening to heavy metal mostly,also jazz, female vocals.
Has anyone heard any of these players in A/B comparisons?
Which one is the best overall,and which one is a best buy?
Thanks

Krell KPS 20il with Gabriel Gold Rapture into a Plinius SA 100 mk III is where I'm at.You can really hear how good the cable is when there is only 1 in the loop direct to your amp
hi priz, a bit off topic i'm currently running a dp500 to a plinius 9200 integrated amp. i'm considering to upgrade the 9200 and wondering if i can just get a real good power amp and connect the dp500 direct. speakers are dyn C1. however i'm worried the range of volume control available on the dp500 (i think it only goes from 1 to 10) would be difficult to work with, especially in zeroing in on a desired listening level. in your setup do you find this to be an issue? would appreciate any comment.
I chose to try a Quad CDP-2...
For some time it will be my reference player. Untill funds allow an upgrade.I still want to go in "one box solution" way,only next time i will go with the player little more expensive.
Then Quad will move to my bedroom.
