    The .5's were the unanimous winner....but the .8's definitely had some positives.

    The .5's sounded fuller, with a greater sense of tonality richness....definitely more tube like if you will.

    The .8's had tighter bass, but more bass, which ultimately created problems in his room. The .8's had a greater sense of speed and dynamic punch. I personally felt like they sounded more like a traditional Class A/B amp....but with some nice goodies thrown in.

    It definitely was closer than you would think. But, at the end of the day, with his associated gear and room, we felt the .5's edged out the .8's.

    I can add:

    I agree the 100.5 is more tubelike .

    My listening impressions got some differences from yours .

    After listening exhaustively the xa100.8 + XP20 + ATC scm100 speakers.


    My first impressions are that the xa100.8 are among the very best amps I had at my demo room before. The


    strenghts are :


    -Sweet and very extended highs , got that result with SET ( tube ) amps only . Maybe the Reimyo KAP is a contender there .


    -Holografic , very good layering.


    -Soundstage , very good .


    -Articulated and present bass.





    Against the xa100.5 that I tested last month, I prefer the xa100.8 in all areas but the bass impact. The 100.5 were far more powerful in the lowest octave. Maybe


    the .8´s need more break in .
    After more than one month of listening the bass impression is the same.

    Thank you Lag; but another such shoot-out I read...said the .5 excelled in all areas, EXCEPT bass control.

    Damn audiophiles!

    The 100.5 were more powerful on bass area in my room with the ATc scm 100 speakers. But that no means them gives better control. The 100.8 were more articulated and thanks that it gets lower . Impact and control are not the same ....

    Re: Pass XA.5 vs XA.8

    Funny how we all end up with vastly different conclusions. I don't think it's the listeners (since the conclusions seem to be from a group of folks in each case), it must be combination of the environment and setup.

    Amps: CAT Legend -> CAT JL7s

    I think a lot depends upon the source.

    Yes , both of you are right. There are other factors that can modify the result. The test I did was in the same room and same electronics+ cables. The source was the Red Reference III player /DAC from Chord Electronics.
    I passed my impressions to people at Pass Labs and them agree with them .

    Just read your comparison on the 160.5 v/s .8.
    I think your impressions are very close to mines 100.5 v/s 100.8 . The .8 has more control .
    What is exactly I feel is about your :
    " 5) The .5's seem to be very recessed in the midrange by comparison. "
    Yes , the .5 is not only recessed but more laid back compared to the .8 . The .8 is not the "on your face" side but is more forwarded in comparison , giving a better layering and spatial resolution than the .5 . If you take for instance my permanent demo Chord electronics spm 1400´s ,both Pass sounds laid back in that area.

    I can live with either amp any day of the year , please don´t misunderstand me . Great amps no doubt.

    Yes of course the other thing is that a given amplifier usually sounds the best with its companion preamplifier (and vice versa).
