Plinius 9100 or 9200

I'm interested in Plinius integrated amp. There is a guay selling Plinius 9100 on Audiogon. He says that 9100 is better than 9200. Most probably he is not honest and wants to get better price or there is something in it? Have you compared both of them?
Something wrong with the manufacturer? Lower price for a better product?
I think you would have a hard time coming up with any evidence that the 9100 is a superior product to the 9200.

He's trying to sell you something, and audiophiles can claim anything sounds better than anything else, so it can't be proven to be a lie.
