deep+333: I see that Luxman also made what appears to be a stripped-down version with remote (the AS-50R) that is selling "new" for $300-350.
@cundare2 I ignored the AS-50R and the Van Alstine as they are powered devices/requires a power supply (an unnecessary complication). The AS-55 does not. I only use it in a "relatively affordable" rig. I don’t use it in my cost no object rig (there is no use case in that room).
I am unable to recall the name of a decent device i had over 15 years ago now from some obscure Eastern European manufacturer. It was around a 1000 bucks and was ok, while it lasted. There are minimal decent options out there actually...If the AS-55 didn’t work out for you, just sell it. At the least, it’s a nice looking piece and some Luxman fanboy around here will buy it (you will get your money back).
You could always get another pair of speakers, i.e. one separate pair for each amp for added variety of sound signatures and forget about switches. One can never have enough speakers.
