Pass XA 25 versus Parasound A21+ - anyone compare?

I have the Perspective 2s.  I run them with my Pass INT-60 in my RoomPlay Reference demo room.   There are a few times that I wish I had a bit more sound level capability. 

IMO, both the Pulsars and the Perspectives are near the bottom of current loudspeaker choices in terms of efficiency.  I would not think that the XA-25 would be enough power.

Of course, their performance - in terms of sheer musical involvement - is at or near the top, well beyond more pricey competitors.  Again not stated as an irrefutable fact, but IMO & IME...

Best,

Did you get rid of the Rogue Stereo 100, or swapping back in forth for a different flavor?

I would also chime in that the Rainmaker is pretty low sensitivity and your room is pretty moderately sized. The Pass does make closer to 80 watts per channel (at 1% distortion) so it should be enough power, but the only way to know is to try it.

Lucked into a used pair of Pulsars last fall. Woke up the bug again and have been replacing everything else I had. Found an Atma-Sphere pre that I've decide is a keeper. Respect to amps, have auditioned a couple ss ARC's (class a/b and d), McIntosh L275 and a Hegel H20 (just what I have available locally to try). Neither the ARC(s) nor McIntosh did much for me. Sound was fine, but little to no soundstaging. Just sounds coming straight out of boxes. The Hegel on the other hand dances pretty well with the A-S and Pulsars. Regardless of volume level, there's an openness and dimensionality to the recordings that the ARC(s) and Mc just don't offer. Not that I take it to '11' all that often, but for such a small unit the Pulsars can actually light things up. And this particular Hegel is more than one would ever need to get the most possible out of the Pulsars in this respect. Do know the Pulsars are very revealing. Good recording (i.e.: Still's 'Treetop Flyer', Patricia Barber 'Too rich for my blood') will put the biggest grin on your face as your windows rattle away. Poorly recorded stuff can become almost intolerable once you've heard how good the good stuff can sound.  

Not fully committed to the Hegel just yet. Will be giving the Parasound a21 a listen. Would love to hear the XA25 as well, but fear that will be a harder find. Would like also to know what the First Watt SIT-3 and Atma-Sphere S-30 do, but again, availability? If you plan on spending any time at all occasional annoying your neighbors (volume up), your likely going to want at the very least 100w/channel for the Pulsars. Efficiency is not their thing. If however, like me, you're willing to sacrifice the ability to rattle windows in favor of the best possible low volume presentation, the Pulsars can that game well, too.

Hi bobbydd

I agree with teajay completely. I have the Pass Labs xa30.8 and it’s basically the same as the xa25 only with balanced inputs and outputs. I also had the Parasound a21 in the past and trust me, there’s no comparison. The xa25 will be so much more musical it’s not even funny. Parasound is good but the Pass amps are, in my opinion, great. That xa25 punches so far above it’s weight class it’s not even a fair fight. I found the Parasound amp to be very boring and just ok. There are some people and some reviewers out there that feel that the xa25’s midrange sounds even better than the xa30.8! I find the xa30.8 to be magical. For under $5000.00 I don’t think You could find a more musical amp. The drive capability of the Pass amps is just insane. My speakers are 83 dB efficient and the xa30.8 doesn’t even break a sweat driving them. Most importantly it always remains so musical. Nelson Pass is a genius IMO. Reliability is off the charts as well. Good luck.
