Yes, they exist. I bought one 10 days ago. What a great piece of equipment! It is 5x180 watts 8 ohms or 5x360 for 4 ohms. I did not compare it with the amps you mentioned, but after 20 odd years of listening to 8 different personally owned systems, I have been impressed with's its clarity, depth and detailing of music. I'm using a cheap set of mains right now and they sound like their worth 4 times as much on this amp. I'll second the request for a power cord recommendation. The manufactures cord is sturdy enough, but it is not shielded. For those yearning to see one, it is roughly the same size as the CAV-500, has a totally flat burnished face plate, with two tall rounded black edges on the right and left edges. I'm still in the break-in period, and so far it has the same smoothness as other Class'es auditioned.
