Pass XA versus Krell FPB Amps

Try a bigger XA series unit,or listen to the X series,though the X units require a balanced input or adapter.

I thought of the bigger XA amps....I am running all XLRs. I like the XA more than the X series so far. Thanks

The Pass XA amps will work better with higher impedance loads, the Krell FPB amps will work better with lower impedance loads. These amps might sound very different depending on the speakers with which they'll be used with.

I have heard both and both are excellent choices you cant go wrong one way or the other. I prefer pass x350.5 or fbp 300.
good luck.

So let me get this straight...Richard Vandersteen does not like Pass amps. Does this mean that Pass amps are crap?

In my opinion:
1 - if you have a room that is treated acoustically a bit too much
and/or
2 - you have laid back, relaxed sounding speakers with bass on the softer side, go with Krell.

For example, I always found Sonus Faber speakers to sound great with Krell amps.

If you have speakers that do not need anymore emphasis on the lower end and in the treble, then Pass will suit those better than Krell.

Krell and Pass are excellent amps with excellent resolution and control. The end result will depend on what speakers and room the amps are used with and what YOU wish your system to sound like. You have to match the components and create synergy.
Trial and error is the only way and only you will know which amp is better for you once it is in your system and you are listening to it.
