I have the apollo I amps, but they should be pretty close to yours in sound. I have had 300BXLS, 842 and now a set of VV32's. I think that the 300BXLS and the 842 tubes are not that much differant in sound. They are both very detailed with a solid bottom end. I haven't listended to the VV32's for that much time, so can't give an accurate account of their sound. I got these tubes from Ron when he had a sale, as spares since they were cheap. I have contemplated getting some of the VAIC tubes, but just haven't wanted to spend the money.
If choose a tube differant from the KR, please post your impression.
