Great cdp's with analog volume control?

I have heard an improvement in performance of CDP with analog volume control, when the analog output passes through the SCE Harmonic Recovery System box on its way to the amplifier inputs.
This is not a preamp, but an optimizer of signal transfer, which actually is rather impressive, and reasonably priced, especially when purchased used on Audiogon.
For those who want to use a CDP without its own analog volume control, I have been using the EVS Ultimate Attenuators, which plug directly into the amplifier input jacks, providing stepped volume control.
Using both of these devices in the signal path from CDP to amplifier can provide great sound in a single source system.

I have personally owned the following CD players and DAC with on-board volume control:

Theta Miles-balanced version(2X the DAC chips of non-bal.)
Cary CD-308
Resolution Audio Opus 21
Musical Fidelity CD/Pre-24
Quad 99 CD-P

Monarchy Model 33 DAC/Pre-amp
Birdland Odeon Lite DAC

All were at least very good. The Resolution Audio Opus 21 was easily the best!

I currently own the MF CD/pre-24 and Quad 99 CD-P.

I don't miss the hassle or cost of a pre-amp AT ALL!

Enjoy,

Hi Reubent,

Thanks for the additions. Looking to sell your CD-Pre24? ;)

I too have heard the Resolution. Fantastic. Have you heard the Audio Aero Capitole?

I'll also advocate for the Opus 21. I've used the Cary 306/200 and Ayre CX-7 (both in need of pre's) and am very happy with my Opus in use of course w/out a preamp.

I've also read/heard wonderful things about the Capitole (who hasn't on the Gon), but I too have not heard it so no help here. When I get the bucks and tire of the Opus, I'll make the move to the Capitole.

Cheers!

Reubent, how would you compare the MF and the Quad?

Thanks.
