McIntosh MC207 or MC402 w/MC205??

I am wondering if anyone has made a direct comparison between the MC207 and the MC402 or MC352. I am upgrading my MC7205 to a MC205 and while I wait for it to ship I am considering the MC207 instead since the dealer has one in stock. My thought is I could use the 7 channels as a 5.1 with the front speakers bi-amped. Or continue to use the 5 channel for Center and rears and my 352 for the 2 channel.
I listen to vinyl and cd 2 channel most of the time and curious if the new McIntosh amps without autoformers sound any better than those with autoformers.
