Pass Labs xa - .5 amps

Leave it in standby between use.

Do not power it down.

Have fun.

I am also looking at purchasing a Pass XA-30.5. Anyone have thoughts or experience with a Conrad Johnson ACT 2.1 and the Dynaudio Sapphires? Sapphires are rated sensitivity specified as 88dB/2.83V/m.<<

I have a pair of Sapphires here paired up with XA100.5. Don't even consider an XA30.5 with this speaker. You'll be very disappointed.

Dealer disclaimer- both brands.

The amp will run out of horsepower IME.

Based on my experience I don't agree.

YMMV

Unlike most amplifiers the meter staff on the XA.5 series indicates bias, not power.

It will move only when the amplifier exceeds its' rated output.

Dealer disclaimer.

So long as the amp output is not exceeding the bias point (in Class A operation) the staff does not move.

Above bias point, the XA.5 amps will source something above rated wattage (they have about 4 dB headroom) and at that point the staff will swing right.

At that point the amp is still in Class A to the rated wattage, but above rated wattage it's A/B. This would be the classic A-A/B operation.

Totally disagree.
