Looking for new DAC: one box or two?

Hello all. I am considering a new DAC to replace my Musical Fidelity TriVista 21, which is fed by a MF A3.2 CDP. For digital, I currently listen only to redbook cd, no SACD or computer audio (yet). I like the sound I have but know that the TriVista is probably quite outdated compared to today's DACs. My question is: should I look for a one box CDP/DAC or a stand-alone DAC that I can feed with my A3.2 CDP (which--knock wood--has been trouble-free for 12-13 hrs.)? Vinyl is my primary source, but I have a lot of cds and still enjoy listening to them. Thanks for your advice.

System: VPI Scoutmaster TT (SDS, upgraded clamp), Soundsmith Paua cartridge, Transparent Reference Phono MM2 cables, Herron VTPH-2 phono stage, Musical Fidelity TriVista 21 DAC, Musical Fidelity 3.2 CDP, Transparent digital cable and music link Ultra interconnects, Musical Fidelity NuVista 800 integrated amp, Transparent Reference MM2 speaker cables, and Wilson Audio Sashas. Also Transparent power conditioner and power cables.
