My Infinity Kappa 9.2i Series II speakers
Hi All,
I'm new here and this is my first post. I have been lurking around for a very long time and reading most everything here, but would now also like to contribute.
I have one pair of Infinity's so far (Kappa 9.2i Series II in oak) and am maybe getting my second pair next week (Reference 60's), although I must first go inspect and test them properly. Not many Infinity's come up for sale here in South Africa, so I suppose not that many were sold here - what a pity. Anyway I am very happy with my set which I purchased used a few years back.
I believe these were never sold in the States, which is a real pity as now there is not that many professional reviews on them - I have not found any yet on the web - maybe someone has a copy of a printed professional review somewhere?
I am attaching a pic of one of my Kappa 9.2i Series II speakers with its cover removed, as well as my user review that I wrote about them as to how to get the best out of them on a shoe string budget, while keeping it relatively 'green' as well. Comments welcome.
My user review for Infinity Kappa 9.2i Series II:
I just love these 2 oak coffins.
Pretty much everything has been said already - just beautiful sound from these 2 monoliths!
Anyway, I'd like to add how to get great sound from them on a shoe string budget.
There must be many other ordinary people like myself that do not have the financial means to go and pick out whatever you like, but have a critical ear and appreciate good sound.
I like classical, 80's pop, house, reggae, classic hard rock, etc. so I needed a system that can cater for just about anything.
I got the speakers at a steal, so that part of the equipment was a no brain-er. The challenge was to get the other equipment together to compliment my new babies.
On my meager budget, it turned out to be a real challenge. At the time I had an AV amp Yamaha DSP-AX1 as well as a 100W/ch integrated amp (Rotel RA-1070) with damping factor of 400. When I saw these 4 12" woofers the first time I realized that 'damping factor' would play a very big role to control these huge cones. This gave me the idea to go for a power amp with a very high damping factor. The best value I could find at the time was a used Rotel RB-980BX, 120W/ch, damping factor = 1000. It did control the bass extremely well, but the high end was not as impressive, as I later discovered. I was using the RA-1070 as a pre-amp from here-on.
I did a lot of research, saved some money and later bought a used Rotel RB-1080 (200W/ch, damping factor = 1000). It was ok, but It was running hotter (which I really did not like), than the RB-980bx, so I advertized the RB-1080 again. At this point I was quite disappointed and just thought I'll stick with the RB-980bx power amp and the RA-1070 used as a pre for now and later start looking again. I was lucky that someone wanted to purchase my RB-1080 to replace his 'light weight' RB-981 power amp to drive his center channel speaker. I read up on the RB-981 and offered to take it as a part trade for the RB-1080 that he wanted.
The RB-981 is 130W/ch and damping factor of 500. As soon as I received it, I did a comparison and as I suspected it did a brilliant job of the highs, blowing the socks off both the RB-1080 and the RB-980bx (for the highs).
So, I now had my bi-amp combo: RB-980bx for the bass and RB-981 for the highs - very, very happy!
Sources and pre-amp was the next challenge:
I was using the RA-1070 integrated as a pre-amp. It was pushing 5Volts, which is pretty loud, but had a pre-amp hum since new. It was barely audible, but it really bugged me, so I sold it. It was also running a bit hot, even with its amp switched out, so I sold it.
I dabbled with a few pre-amps as well as AV amps as pre-amps. Eventually I saw the light and decided to try my iPod directly, using its built-in pre-amp. Wow! Obviously the best pre-amp, is NO pre-amp at all!
So, I gave up a CD played and tuner - so what? I had ripped all my cd's anyway.

I had used various Apple iPods for many years and some are better than others. The best of the best is my latest (by a huge margin) the 3rd Generation iPod Touch 64GB. The sound is just absolutely in a different league to all the previous iPod's.
So now I am running the Apple iPod Touch 64GB in the original iPod Dock with IR remote. I use the original Apple iPod AV cable, power supply and IR remote that came with the dock. I then split each of the left and right RCA's to the 2 power amps, which Bi-amp the two Infinity Kappa 9.2i Series II speakers.
The whole system uses no more than 50 Watts AC power, has no hum or line/gain noise what-so-ever.
Oh-yes, I made up my own speaker cable, using old ICL inter-mainframe comms cables - it took many, many hours stripping very fine strands with my finger nails, as it is very fine and fragile (each individual strand), but it was well worth it. I have tried many branded speaker cables, but my home made ones are best by some margin IMHO and seems totally transparent.
I am done looking for 'better' equipment. I am very, very happy with my whole system... on a shoe string.
I hope someone out there can get some inspiration from my journey and not just settle for an off-the shelf system that can never give you the satisfaction of a well sorted custom system.
