opinion on Omega Super 3i speakers

Awesome, much appreciate.

I don't know about the Super 3, but just bought the Super 7 Monitors Mk2. I'm breaking in the speakers, so far they played for about 10 hours. 
I'm using them in a small room connected to a little tube amplifier (KingKo Audio KA101, 12W in push-pull using EL84 for power).
These speakers play loud without loosing on detail and clarity. Their sound is a bit to the warm side, I would say - not crisp and analytical. I like the combination with the tube amplifier. 
I guess these are an upgrade on the Super 3 and that's up to your room and wallet which model to choose. 

Love my Super 3i's. I purchased them in the fall of 2016 and have no desire to upgrade, however, if I did upgrade I would go with the Super 3 High Output Monitor (there's a lot to like about that 4.5" driver). I now have them paired with a Decware SE84UFO.

Aside from the electronics, the choice of the single driver design monitors depends completely on the type of the music played through them. In my experience, for anything but jazz, blues, or instrumentals/vocals, I'd look elsewhere, e.g., rock, orchestral classical, etc. 

Kalali, I both have the omega rs8 supercone and the 3i they will almost play any music.My rs8 they are as good as my tekton impact monitor, on vocals omega are hard hard to beat, I play them with Gumby dac, art audio preamp, and art audio concierto tube amps, Teo cabling ic, and Audioquest Sterling speaker cables...transport ah tube CD player... the rs8 are 98 dB...Hifineubee Lois is a very nice guy, and he knows what he is doing....You will need sub for the 3i to really appreciate them.omegas like tubes
