I put my 400cx on a Lovan Sovereign amp stand; two of these would be perfect for your 450s. Enjoy those! They are amazingly great amps.
Amp stands for Krell 450 monos?
I now have my new 450mcx monos (wonderful amps!) direct on a wood floor. Is there a big improvment in sound putting them on stands? Which stands? I use Audio Artistry Beethoven speakers and I play loud so there is for shure floor vibrations!
