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

I believe it is worth it. I own the Cremona M (purchased new two years ago). I also love the Simaudio sound and I auditioned both the the i3.3 and the Sim audio I7 (since been replaced by 600i and 700 i) with my Cremonas.

I found the 3.3 to be very melodic and dynamic but couldn't match the i7 in terms of soundstage and transparency. I ended up buying the i7 and the Supernova CD player as part of the system with my Cremona Ms and absolutely love the combination.

Thank you for your comment in regards to the upgrade from 3.3 to 600i. Matter a fact, i did upgrade and now a proud owner of the 600i. Overall, i love it and combination has worked well. Did i understand your post correctly? Do you have or tried out the 700i with the cremonas? I find that i need to turn up the 600i to a reasonable volume (50) to get the full dynamic sound that im looking for. Wondering if i should upgrade to the 700i.

glad to hear you made the upgrade and am not surprised you have noticed an improvement with your great speakers. You should really consider the 600 as equal in quality and peformance to separates in a great looking package. I really lusted after the red limited edition version in the magazines. I am not sure how high the vol goes but that should not be an issue going to 50-you really can't hurt good gear and as long as it is not clipping no problem to amp or speakers. I really like the power of the 700 and it depends on if you feel your current set up seems strained (which I bet it doesn't). I have large floorstanders as well and I find the same applies and this is more a issue of speakers (db/efficiancy). I love low level listening but you sure notice in rock etc when you give it some juice-the music needs it. Would the store let you try the 700 in your system to see if it really makes any diff.
