To upgrade from simaudio 3.3i to 600i or not?

Camb, it appears I am right where you were when you decided to move up to separates. The 600i sounds good, but lack a bit on the bass and light in sounding when playing through the Ketemas. Considering moving up to sim separates. The cost will be steep even with the trade in. Any regrets moving up?

Nope, no regrets. Funny you mention the power issue - the reason I went to Sim separates from the i7 was that I read my speakers perform best with 300wpc. The Sim W8 puts out about that much power into my Revel Studio 2' 6 ohm load. I'm not sure I'd say I got MORE bass with the Sim Separates in place but I do get better bass CONTROL. It's punchier, faster and more "granite-like" or solid. Maybe a little deeper, too, but not much.

Your speakers sound even more demanding than mine so maybe you would benefit more. If you have a chance to try it out first to see if it gives you what you're looking for.

Thanks Camb, I appreciate your help. It's the price increase for the new sim separates that makes me reluctant. I'll wait to audition them when they become available.
