Musical Fidelity A5.5 CD vs X-Ray V3, and related

I currently have a Musical Fidelity X-Ray V3 CD player + X-DAC V3 + X-10 V3 Tube Buffer + X-PSU power supply running through X-150 Amp to Focal JM Labs Chorus 714 speakers.

I'm upgrading the amp to a MF A5.5, and upgrading the speakers to JM Labs 928.

Question is - is it likely worthwhile to upgrade the X-Ray V3/X-DAC/X-V10 to the MF A5.5CD player, or is there going to be negligible difference between the A5.5 and the existing X-Ray set-up?

If anyone has experience of comparisons, I'd be grateful.

Also interested to know of any other recommendations for CD players in similar price range to MF A5.5 that may better the X-Ray/X-DAC.

Anyone have experience yet with the Naim HDX CD/Hard disk player?

Thanks.
