If your willing to pay the price; a Manley StealheadĀ @ $8500.00 fits the bill. I have a Steelhead bought in '07. Just talked to the Manley folks this week; if you can find a used one ; remote volume control can be retrofitted . I am currently driving a pair of Pass Lab 160.8s to very good effect with the Steelhead. Like it better than the Spectral electronics that are now on the market
