New Amps to match up with PSB T3 speakers
An amp cable of running into a 4ohm load continuously without breaking a sweat, would be ideal, as this graph shows most of the bass will present to the amp as 4ohms, and that’s where all the power is needed.

The minimum value is 3.5 ohms at 85Hz, and the phase angle (dotted trace) is generally low. Any amplifier that is comfortable driving 4 ohms will have no difficulty with the Imagine T3.

Whatever you get, see if Stereophile has done a review on it, and see in the test bench measurements if it’s happy doing 4ohms.
