AU-D11 and AU-D9 power output for a 6 ohm impedance load?

So maybe this is a very stupid question but it seems like most of the speakers I like are 6ohm so far. And despite the fact that I know that impedance load modifies wattage output form the amps, I always think of my Sansui's nominal 8ohm power output. Does anyone know the real-world power output for the D11 and the D9 for 6ohm? how about for 4ohm?

Thanks

From that review the AU-D11 performs extremely well into even 2Ω loads, and as the AU-D9 is the same design but a lower powered model you most likely can expect a similar performance. Although neither should be considered good to use with 2 pairs of 4Ω speakers at anything other than low or moderate volume levels. This is because the testing into low Ω loads can only have been done briefly, and only at one frequency, just to see how much power the amplifier could produce if driven hard - even though the graph is labelled 'continuous watts per channel'. ;)

Here's the last page of the review in case inquiring minds want to know ;)


Love the wrap-up!

"To assess the Sansui AU-D11 properly, one should think of it as a state-of-the-art amplifier built for the most discriminating audiophile, rather than just another high -price product from a large Japanese manufacturer. Assuming that its power is adequate for the intended use and that no serious objections are raised to any of its control features (or lack thereof), we believe that there is no better amplifier to be had today. Naturally it sounds as good as amplifier can sound. This flagship of the Sansui line is an amplifier whose performance, combined with full protection for itself and the speakers, may possibly be equaled (though not cheaply) but is not likely to be surpassed. If something better came along we doubt that it could be measured with today's instruments, since ours were operating at or beyond their design limits during our tests of the AU -D11"
