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

Never tried it, but assume you connect to the fixed output of 600i to high input of subs. Let me know how it sounds. Thought about doing it myself. I have the 300d v.1 DAC. You can get the version for cheaper since it only upsamples to 94. Look at my virtual system for details. Honestly, the 300 and 100 simaudio sounds the same. 300 have xlr output, which is only difference. I listen to mostly vinyl, so I did not splurge on the DAC. How does it sound, ok, I guess.

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.
