I agree with Barrelchief and Art - that's what I've done. The tube glow is a bonus!! I was quite surprised by how much better the presentation got adding the 2nd 300.1 amp. Way more of everything - more air, bigger soundstage, better imaging and more organic. Also much better bass depth, control and speed. Definitely took my system up a few notches and would highly recommend you do the same if you can swing it.
