Help power pair of Infinity Kappa 9's please

What about the Krell MDA 300 monos? anyone? can they do it?

Steakster, I also own two of the Sunfire Signature amplifiers. It will power the Kappa 9 sufficiently, but not optimally. I put two of the Sunfire Signatures on the Kappa 9 in a vertical biamp configuration and it takes the listening experience to a whole 'nother level.

I put a pair of my Pass Labs X-600 monobloc beasts on the Kappa 9 they didn't get it done, I needed two pair of the Pass beasts to get the speakers to wake up and sing.

The bottom line here is that the Kappa 9 need gobs of power for optimum results.

JT, get rid of them and get the Kappa 8.1 or 7.1 and you'll be much happier and save yourself some money in the process. The Kappa 9 are waaay too much for a room your size.

The Kappa 9 has been known to cause grief to many audiophiles over the years since its introduction. It is, what I consider, a poorly designed speaker because of the difficult load it presents to the amplifier. Even if you find an amplifier to deal with the load, which would be very expensive, the amplifier's sound will be degraded due to the speaker's load.

It makes more sense to design a speaker with a reasonable sensitivity and an amplifier friendly load. This type of speaker design will always produce better overall sound.

Paul Klipsch was often quoted saying "What this country needs is a really good 5 watt amplifier." What would a really good 5 watt amplifier do for an Infinity Kappa 9?

A good solid state amp that is basically an arc welder will work fine with your speakers. however, you have exceeded your budget. Which is not a problem if you are not in a hurry. do one thing at a time. Don't rush. Mark Levinson 23, 23.5, 20.6, etc. Big Thresholds, Krells, will work fine. you just have to determine which amp's sound you like. Also, if your CD player has a volume control, you don't need a pre-amp at this time and can get one later and stay within your budget. Upgrades should always come one at a time. So, lets say your CD player has volume control, then you only need the amp as long as you like the DAC from your CD player, which in my opinion, typically are not very good because the power supplies are very bad in most CD players. As long as speaker placement isn't a problem, the room size of 12 x 12 isn't a deal breaker. Then, later get a decent DAC and use your CD player as a transport. That will make a huge difference in sound. "if" your CD transport is decent.

my opinion, small steps. one upgrade at a time. make friends with the sound of the equipment before upgrading.

The only amp that I can think of that can drive them well, I don't think will sound particularly good with the Kappa 9's. That is an old Sumo Andromeda. The Original, Not the II or III. I've driven that very loudly years ago into 3 ohms without issue. It is a bit dry in the mid range and High end. I doubt your emits will like it.
