Ah.. The Krell KAV-300R. Produced for a short time in the late 90's and not easy to find. It's basically a Krell KAV-300I integrated with a tuner by Day Sequerra. It puts out 150 WPC into 8 ohms and doubles to 300 into 4 ohms. Put together with the build quality you would expect from Krell. Even the remote is solid metal.
All made in the USA to boot.
I drooled over that one when I was just getting into this fun, it was out of my reach then. Very nice!
