I want to build an audiophile grade 300-500W Class A/B mono power amplifier to power a passive 8 Ohm 12" subwoofer. I do not want to use a plate amplifier but rather build a stand alone power amp. The "honey-badger" would be a great option except it is limited to 150W @ 8 Ohms. I also do not want to use a digital amplifier design. Any suggestions?
Marantz MA9-S2 is 300w per channel into 8R.

Very nice amp, maybe too nice for a sub.
OTOH if there is anywhere a class-d amp would be hard to argue against, it would be for a sub.

If you run the Badger with the largest (highest SOA) outputs and a 35-0-35 trafo (47V DC) , you can easily get 250W out of the Badger.
The Wolverine 4X board with MT-200 Sankens can push 400W/ 8R , it has a EF3 - better for Bass.
