Default pass X 1000.5 or Xa 200.5

Difficult to choose between him X 1000.5 and Xa 200.5, somebody of us would have been lucky to listen to these two amplifiers I look for transparency, heat, sweetness and dynamics on wilsons 2s maxx
you Nelson which indeed his, what amplifier which both would put you with Wilsons

Salut Robin,

I had the chance to listen to both amps with Wadia digital frontend, TW Raven, Graham Phantom and Koetsu Rosewood on X ONO and a X0.2 preamp as analogue frontend.

Both poweramps were setup with either B&W N800D (far from being my favorites), Audio Physics Medea (much more like it) and Wilson Alexandria.

Personally I would go for the XA200.5! On any of those speakers the XA200.5 had a slight advantage, musically more own 2c...

But on the other hand, we are talking really big rollers here...

hello mach

I think as you ,the Xa 200.5 really has to have a good sound, but in front of this level , i always ask the question: whom to choose
i like very much the class A , in spite of their weak return
thank you

Hey Robin,

the XA200.5 is a Class A product as well. It will not work throughout all powerrequirements in full Class A and revert to A/B but this is not noticiable.

For this, I highly recomend the following article: Leaving Class A | Pass Laboratories

In my experience, the label "pure Class A" will haunt your mind and you expect a more perfect performance out of this iso an amp reverting to Class A/B at some stage.

And lets face it, at certain volume levels, you will have much more distortion from your speakers (yes even the Wilsons! @ 90dB+) and your listening environment, than any good Class A/B amplifier will ever produce.
