Probably has the Simaudio "house" sound which is great if you like it. I owned the I-5 LE for about 6 months until I couldn't stand the weak, ill-defined bass anymore. Treble is great but that's their strength so you get this great soundstage until you notice that there's no boogie in the Sim's steps.
Since Simaudio stuff ain't cheap, get your dealer to give you the amp for the weekend and try it with YOUR setup - many of the Simaudio dealers know that Sim stuff runs lean and they pair it with Cardas Golden Cross (warm cables) and an ultra-expensive speaker setup to compensate (extra bass).
I'm not saying that it's terrible stuff but that system and room matching with Simaudio equipment is a must or you could end up with a lean system like I did...
