So I currently have a Carvin FET1000 power amp being driven by an Eden Navigator. Carvins have always seemed conservative in their ratings, and this power amp, while reasonably powerful, seems to be no exception. I'm looking at a used Crown Power Base 3 and I'm hoping that it will be appreciably more powerful for my purposes. I know that this is subjective, but if anyone has experience with it, please chime in on your perception of its adequacy of power. Also, I noticed that there are no output adjustments. Does this mean that it runs full "volume" (or power) all of the time and that the volume adjustment should be made with the preamp? I've switched my philosophy to that of adjusting the master volume at the power amp level for signal-to-noise considerations and I'm guessing that I will now have to adjust the volume at the preamp output level. Is this correct? Apologies if these are stupid questions. Any advice/opinion on this power amp would be greatly appreciated. Thanks in advance!
