Krell showcase or other 5 channel amp

I own a Parasound 1205A and am looking for something that would be an upgrade. I want an amp with balanced inputs and need it to be in black (which seems to cut down your choices in high end amps these days). I am wondering if the Showcase would really be an improvement over what I have. I am somewhat suspicious of these newer Krells (as compared to, say, the Krell TAS which looks like a real Krell!). Would I be getting just the name or a real sonic improvement?

I have B&W803N's, and would get a Classe, but they seem very rare on the used market. The Dreadnaught seems like a great idea, but perhaps a bit more expensive. Any other suggestions?
