sejodiren,
Your post is welcome, as it illustrates quite well this concept of "doubling into 4, doubling again into 2" is just a "lazy mans" spec. It sounds impressive, but only if the design is conventional, and even then, the only specification that matters is how many watts at your speakers lowest impedance. 300 watts into 2 ohms, and 150 into 8, is still better than 200 into 2 ohms, and 50 into 8. The Proton, which does not increase that much into 4 / 2 ohms, has a design methodology based around real world music where peaks are short in length, and for those peaks, it can deliver significantly more power (headroom). It's this headroom that makes an amplifier deliver above its rated continuous wattage (which you can only compare at the same impedance).

It makes my DQ 10's just sing compared to the Yamaha SS receiver I was previously using at 95wpc in 2 channel mode. I don't know a whole lot about the 'techy' stuff but I believe it's a class g/h? Incredible sounding 'little' amp for sure..... http://www.hifi-classic.net/review/proton-d540-410.html
