amplifiers for Kappa 9's

I have seen some feedback in here about the use of Bryston Amps for driving Infinity Kappa 9's, and agree that these are not the best amps to be using for these speakers. This is how my current system is set up, using 2 4B-NRB's, 10B Crossover and 12B Preamp... and MIT Cables throughout. I do find my Kappa 9's are very bright, but do not lag in the bottom end with the use of my Bryston amps. I am thinking about going to a tube amp for the top end, such as an Audio Research VS-110. I feel this will compliment my system quite nicely, however, any input or feedback about my idea would be appreciated.

The impedance of those speakers gets very low which would probably be a problem with most tube amps. I know a Parasound HCA 3500 will drive those too but many amps won't due to the very low impedance. Do a search here and you'll find more info.

I was checking out the crossovers in these speakers a couple of weeks ago at a friend's home. WOW these things have a lot of real estate inside of them! Just from the looks you need a mammoth amplifier to get the best out of them. I bet a Carver ZR1600 would spank them like a red headed step child.:-)

Good luck with finding a tube amplifier for those monsters!

Those speakers would suck a Carver Pro ZR1600 dry. You need BIG power with those if you really want to raise the roof and keep things relatively clean. Sean

Hey Sean how about two Carvers run as monolocks? You think it would suck them dry? I have no doubt they need some serious current. With all those parts, it's a wonder any signal ever makes it to the drivers.:-)

Or how about a Carver ZRx3200 1600 wpc into 2 ohms. Or two ZRx3200 monoblocked with 3200 wpc into 4 ohms! This model may do the trick.LOL
