Thank you for the fantastic work you do with measurements. They have been a great tool, allowing me to narrow down the field when shopping for new products.

In Fig.5 it looks like the power output is actually 250W at 1%, not 235W. At 0.1% however it looks more like 235W. Was this a typo? Can you confirm this?

I'm using this amp to drive a pair of Revel Studio2s. My calculations tells me 235W is precisely enough to cover peaks of up to 105dB at my listening position, 9 1/5 feet from the speakers. Would you agree this amp has enough power for the Studio2s?
