Amp Options - Infinity Kappa 9s

Hi All,

I recently made my first foray into some upgraded speakers and settled on the Infinity Kappa 9s. Being a novice to the HiFi game still, I didn’t have a full appreciation for just how hard these things seem to be to find an amp/s for!

I’ve spoken to a few people and been given different paths. I’m just hoping to get some advice on a few different options. Any input would be much appreciated as I start to build my knowledge. The 3 amp options I’ve been presented are below. Would any of these run well in either/both of the Normal/Extended modes for the K9s?

Cheers,

Ash

Pair of Xindak XA8800MNE (200W, Class A Monoblocks)

From what I can find, these are only rated down to 4Ohms but he had them driving Infinity RS4.5s which seem to have similar issues to the K9s.

older strong class ab solid state amps by top makers should definitely be considered, as mentioned (newer ones too, of course)...

look at other threads here seeking amps for magnepans... same answers for your kappas more or less...

There is a Classe Audio DR-9 on USAudiomart right now that would be perfect for your Kappa 9s. I have used this exact combo in the past and it is quite good. The DR-9 won’t even break a sweat…

what Russ said. Last,amp you will ever need!

 

almost unlimited power, the Magtech monoblocks, kicked the MBL Radiostrahler speakers in the pants, as not many,amps will.

Hey Ash, some of those crossover upgrades significantly improve the impedance relative to original, so I would not necessarily compare them to a production unit.

If you have one of those impedance improved crossovers just about any reasonable amp will work. 

I do think you need to broaden your listening horizon though for amps:

 

  • Ayre
  • Luxman
  • Pass

are alternatives you really should consider.  However, given the unique HF drivers you really should audition them to make sure they are a good match.
