The LS-3 without a remote is a real high-end preamp that is not out of place in a revealing system. It is grain-free, dynamic and transparent, especially through the direct input that bypasses the channel selector and balance control.
The remote volume control will reduce its fidelity. As for how it sounds compared to the Adcom (I used to own a cheap Adcom) and the Parasound, I do not know, but given that most mid-priced solid-state preamps sound mediocre and given how good the LS-3 sounds, my guess is that the LS-3 will sound better in most systems, especially in a system featuring a Bryston amp.
