Power amp for PSB Gold i's

The Goldi's need a lot of horsepower. I agree with the Classe suggestion of the previous poster, and would add a Marsh A400 and perhaps an Odyssey or old Carver. Depending on your passive preamp, you might actually be better selling it and using the proceeds to purchase a used high-powered integrated amp, such as the Plinius 8200.

I agree with Gbart that you're looking for an amp that can double down. You're looking in the right power range, although I don't think there is a specific wattage that will work with the Goldi's, it just depends on the individual amp and how beefy it is.

I also agree with the McCormack suggestion, although I still think that in your price range the big Marsh amps will provide the best bang for the buck.

If you can stretch your budget a little, the Wyred4Sound amps sound like they might fit the bill perfectly, as they've been getting a lot of buzz, although I haven't heard one. Or, sell the preamp and get the Wyred4Sound integrated.
