Hibachi I/II put out around 220w into 4 ohms. They are nice solid amps as I use a pair to drive a pair of PMC OB1's. Paul is a stand up guy and his gear is top notch. If you're looking at the pair for sale on the forums for $550 shipped they are a steal at that price (so much so I was thinking of purchasing them for bi-amping). Seriously, you'd have to spend $1k to get the same level of performance. As with all of Paul's designs, the cost to value ratio is through the roof.
BTW I also own his PreDAC and have owned 2 of the TAD-150 Signature preamps he used to sell. The 150 Sig being a phenomenal value as well.
