i do think tat a Class D Amp is better for Speakers like Kappa, if you don't want to spent +$5000 on a Class A/B. Anyway , my main question was about the quality of the Old Kappa's compared to the new Speakers.
when I had the ren 90's about 5 years ago I didn't think anything under 10k new came close to them when I was auditioning new speakers at the time.Funny, we're comparing a $5000.00 pair of speakers to the Kappa 8 which can be had for $500.00. I know we are not to talk value in this forum but I feel it has to be said...
A Class D amp will do nothing but puke out at less than 50% output on original Kappa's--the fallicy being that they need a ton of power--no-- they don't--they need a ton of current--which is a whole different animal. I have Kappa 9's--the true "amp killers", and either bi-amp them with two Aragon 4004's or quad-amp them with four Krell KMA-160 monoblocs--in any case the amps have to be stable down down to 2 ohms, or 1 ohms (optimally).
normally I would agree but the NAD M2 is a pretty worthy amp, the amp can pull nearly 30a of current under max load, It's a class D I can respect.
Adjusted for inflation they're not that far apart. The Kappa 8s originally listed at $2k/pair in 1987 (adjusts to $4250 today according to CPI calculator). At the time the Kappas were pretty technologically sophisticated (consider the amount of bass they're getting out of a relatively small cabinet - yeah, they look big, but they're very shallow - about 2 cu ft by my calculations).Funny, we're comparing a $5000.00 pair of speakers to the Kappa 8 which can be had for $500.00.
