CD Player with volume control to drive my Nuforces

Just for fun, I want to try a CD player with volume control (analog if it's possible), to drive directly my Nuforces Ref9 V2. I think in 3 options: Audio Aero Capitole Reference, Ayon CD-2, Cary 303-300 or other with volume control ( Like the 308).....

I usually listen to all kind of music (rock, pop, electronic, fusion, bosa, jazz, but not classical !!).

My system is:

- Dynaudio Confidence C2 (cable Analysis Plus Oval 8)

- Nuforce Ref 9 V2 (JPS Superconductor Q IC's)

- ModWright SWL 9.0 SE Linestage

- And the sources are:

1) Macbook connected trough a Polestar USB cable to Havanna DAC USB (with Modded Analysis Plus Solo Crystal Oval IC's).

2) Modiffied Oppo 981 HD as transport, connected trough a Nordost Silver Shadow Coax with the CI Audio VDA-2 DAC plus VAC-1 Power Suply.
