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

Congratulations on your upgrade!

I am using a Simaudio Moon Evolution 600i to power a pair of Totem Tribe III and I also have a pair of Focal Chorus 836W setup as well. Do anyone 600i owners know how I connect a sub into the mix. I can't figure it out for the life of me.

I also want to point out that I have never been so thrilled with a piece of gear in my life as I am the 600i. I said bye bye to McIntosh the moment my ears first heard some of the Simaudio moon gear.

Also having trouble deciding which DAC to get. Trying to make a decision between the Moon 300D and the Bryston BDA-2.

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.

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.
