Who has heard the new Pass XA25?

Hey bobheinatz,

My review on the XA-25 should be put up on hometheaterreview.com in the next two weeks.  I own a pair of XA-60.8 mono-blocks and a First Watt SIT 2, they are great amplifiers.  However, for my tastes I believe the XA-25 might be the best amplifier that Nelson and his staff have yet to produce in their long storied history.  If it was not for it's lack of background noise and its dynamic control of the low end, you might think you are listening to a SET tube based amplifier because of the purity/density of timbres/tonality and how it has 3D "meat on the bones" imaging that you rarely get out of a SS design.  Take a look at my review for a lot more details why I have made this my reference amplifier in my reviewing system.

Thanks teajay,
I will certainly check it out when it is available.

@bobheinatz I heard the XA25 briefly at CAS a few months ago. It was in a modest room, with a HPA-1 used as a preamplifier and I believe an Oppo source. Speakers were some Vienna Acoustics floorstanders that the Pass rep said "were what I found in the warehouse." The sound was warm and full but a bit sluggish and laid back for my tastes... but given the setup I can't pin that on the amp at all. The other comments are certainly interesting... I might just have to see if I can get one in-house for review...

Hey bobheinatz,

Here's two more reviewers that have raved about the XA-25:

1) "the audio beatnik" on his website did an excellent job of comparing the XA-25 to his XA-30.8.  He's a good writer and has excellent ears.

2) On the website Audiophiliac, Steve Guttenburg has also reviewed the XA-25 and fallen in love with it. 

I'm in basic agreement with both their perspectives on this amplifier.  The major difference is what preamplifier they used to drive it.  I found the combination of the Linear Tube Audio Micro-ZOTL with NOS tubes with the XA-25 to be a remarkable match made in sonic heaven in my system.  

Hey Guys,

In the February edition of Stereophile the reviewer, Herb Reichert, gave a superlative rave over the XA-25 performance.  I believe he kinda missed how terrific the amp's tonality/timbres and its rendering of 3D/imaging and space are, but he did get how quiet/transparent it is compared to his SET tube amplifier or possibly any amplifier on the market, along with its speed/power/control overall.

John Atkinson's measurements showed that the XA-25 greatly out-performed its stated power ratings significantly, indeed.  It's specified power out put is 25 watts into 8 ohms and 50 watts into 4 ohms.  Atkinson's measurements were 80 watts into 8 ohms and 130 watts into 4 ohms.  

Pass Labs is always quite conservative in their ratings to begin with, with the XA-25 this little amp in size is quite the powerhouse hitting way above its ratings.
