MF A308 amp/pre vs. MF TriVista int.

I'm thinking of upgrading my A308 int. amp to either A308 separates or a Trivista int amp. Has anyone compared these two? I like the MF "sound" so I am not thinking about other brands. I don't live close enough to a dealer to listen to them,so any thoughts will help.
The Tri-Vista and 308 series are completely different animals. IMO, if you like the 308, you're going to flip over the Tri-Vista.
I did the direct comparison. No contest. The Trivista brings out base in the N802s that I didn't know they had. And after one year the Trivista sounds better than it did after 6 months of being run every day for 1-2 hours. It is a steal!!
