Planning for a possible face-off of DACs/CDPs

I am planning on upgrading from my Rotel RCD-02 CDP this fall (finances permitting). My price target is ~$1K. The 2-channel sub-system of my combo HT/audio rig consists of the Rotel, a C-J PV11 preamp, Odyssey Stratos amplifier (with cap upgrade), Vandersteen 1C speakers with V2q subwoofer. Cabling is mostly BlueJeans (Belden) and entry-level Kimber. I believe the RCD-02 is the current weak link in this system, which can sound pretty good with audiophile CDs, but is harsh and "digital" sounding with most CDs. I am looking to maintain the Rotel's wide soundstage, increase depth, improve detail, add smoothness and reduce grain and grit. I would also like to reduce congestion when listening to rock and full orchestras. I have a few HDCDs, and I'd like to retain this ability, but it is not a deal breaker.

All candidates must be near the price target of $1K or less and be available for in-home trial. I will keep the best of the batch. If a DAC is in question, I will use the RCD-02 as the transport with a SignalCable coax digital cable.

Current candidates are:

Eastern Electric Minimax CDP
Vincent CD-S1.1 CDP
Lite Audio DAC 62 *OR* DAC 68, both modded by Pacific Valve
I'd appreciate guidance as to which of the above DACs would be better suited to my goals.

If anyone has any suggested additions, please post. Remember, it must be available for an in-home addition, so please include a retailer source with the model suggestion. Thanks in advance. I will post my impressions here sometime later this year.

Note: I have tried the Jolida JD-100A, in stock form, and did not hear a noticeable difference between it and the Rotel in my system.
