Hello, I just joined, primarily for the audiophile products. Looking at purchasing the NHT C3 speakers for our new living room. Space is about 15 feet wide by 33 long and they will fire long ways. Space is just for general listening, music room with all equipment is downstairs, so hoping they will fill it with sound nicely. Cheers.

Anyway, should work great for 50 ohm and above, probably Ok down to 32 ohm.
What no one has mentioned, if global feedback is used, then equivalent output impedance should be lower.
The chip used has high bandwidth and slew. Usually designers add output resistance for stability, like with Topping A30. This is the trade-off. Up until a few years ago, no one would think of designing an amp without some output impedance. I think that owners of 16 ohm Iems or multi-driver iems with poorly designed crossovers, should look at something like O2. Of course, the result of using those with this amp would be flabby boosted bass, which some people like anyway. Also, if there is feedback, maybe this won't happen.
