I'm confused by your question. If you liked the presentation of the Pass Labs amplifier better, why bother? Your system seems impressively complete and up to date not to mention the one manufacturer synergy you've got going on.
If you decide on some NuForce amps try the 9SE's and remember they're very sensitive to VAC, associated cabling (use copper), and mechanical vibration.
