Regardless of wattage needs, there are definitely some speakers that benefit from amps with higher current output and/or higher damping factor. I've heard this with two amps demo'd on the same speakers.
What is the appropriate horsepower (wattage) for a new pair of PSB T2's?
I ended up upgrading the Imagine B's with a pair of PSB T2's. As good as the NAD c356 sounds, I think the T'2s could use some additional wattage. Any experience out there with the PSB Imagine line? Also I have a flawless pair of Imagine B's for sale.
