I heard the Viva preamp recently and I must say it is world class.
The preamp + monos are very, very serious $. I wonder what kind of sonic premium they offer over the integrated.
My guess is not much if you are not driving the amplifier too hard. The topology, circuit, parts are all the same - just three boxes vs. one so you get the separate power supplies.
The convenience of an integrated is nice, although moving it is no fun.
