Acuscott,
The Denon with 2V will be fine. But I doubt about X-LPS with 350mV. The sensitivity of the Rotel (1.5V) is just about OK for a TVC. The higher the sensitivity (lower numbers) of an amp, the better it matches with TVC. Please check with Promitheus with your specs and they should be able to guide you. Check with Nicholas is a 6dB gain would work for you.
The Promitheus TVC is a great product - but only if you achieve the system synergy. Good luck.
