I have owned quite a few Mac amps. My favoirte was the MC-2300, which did not have an autoformer. With regard to Macs power rating CONSERATIVE is their practice. The MC-2300 could put out nearly 500 watts into an 8 ohm load though rated at 300 per side. Strapped in mono, power deliery was astronamical, as it would easliy better 1500 watts. I know beacuse I still have the bench sheet from my personal amp tested during a Mac clinic.
Further, this amps was factory rated to drive a half ohm load. Not many compaines have that type of confidence in their products ability to drive loads. Damping factor was always stated with low numbers. This is because a damping factor of more than 20, was thought to be inaudible and ridiculous according the Mac engineers of the day, so that was all they ever tested for. Any Mac amp when tested will easily give you a high damping factor.
Mac specs are always quoted as "worst case". Who else does that? No one I can think of..
