In my case it wasn't just a matter of precisely aiming the remote within the Pre90's very narrow sweet spot. The Pre90 didn't always respond on the first button press on the remote. It might respond on the 2nd press and but subsequent presses of another button immediately following might not work. Had to wait, then go through some button gymnastics for the Pre90 to respond. It became very annoying.
ONE of the purposes of a preamp (for me) is to offer the convenience of source switching and volume control via REMOTE. If that fundamental requirement is flawed it becomes an annoyance and gets booted out of my system.... as did the Pre90.
