If you've done much reading about the two brands you know that they're both almost universally highly regarded.
The best you can hope to get here in terms of advice, if you're lucky, is to find one or two people who have had both brands in their own system and whose system includes the Forests. Their opinion might be really valuable to you, if they happen to have ears that closely match yours, as well.
I own and love the Simaudio I-5 but I wouldn't recommend it to you just based on the fact that it sounds wonderful in my setup.
Unless you're able to audition both amps yourself I think you're better off taking Mechans' advice and buying the one your wife prefers. Of course, if you've already decided you want the Plinius and are looking here for justification for buying it rather than the one your wife wants, you're going to need counseling of a different kind.
