Bryston 4b monoamp matched to Infiniti Kappa 9
 

My brother is interested in buying new amps for his Infiniti Kappa 9 speakers, any other recommendations besides biamping Bryston 4b amps ?

David.......Why Bryston? His choice?

His budget is $2000

What's his source component?

David.......I sold the Infinity Kappa 9 speakers new back in the early 80's at a high-end shop in Beaverton, Oregon. We use to drive them with Mark Levinson. They are power hungry monsters. 200 watts would be the starting point, whatever he decides to use.

Audio Research Sp 9 pre amp. , CD player is Nakamichi . All his stuff is late 1980's

are they worth it
 

Hi Dan and thanks....this is mark...the brother...are they worth spending the money on...i love the speaker but they are underdriven at this point... i want to make them pop again..... what did you think of the speaker as a whole

He needs to upgrade his source component - let him know that I've got a nice MCD201 CD/SACD player for sale-only $1450.00 + S/H. :D He'll some money left over for some new CD's. ;)

my friend suggested bi-amping the speakers with the bryston 4 b's...

Mark.......Welcome to Audio Aficionado. Your brother should be the first to tell you hanging around here can be financially dangerous. Now, lets spend some money. :D

I like the Infinity Kappa 9's. The oak cabinets were gorgeous. The cabinet design looks current even against what is available today. There biggest drawback is they need power. Maybe an MC300, or an MC7270 would be the starting point. Those are both great amps, aren't budget busters, and you see them around fairly often. I owned a MC300 for 13 years, and loved it. It was performing as good they day I sold it , as the day I bought it new. I suggest these amps as an attempt to stay within the price range David stated.

You may want to recap the Infinity's crossovers, too. Some 20+ years make old caps suspect.
