Pass Labs Int 25 vs Int 60

@audiofound 

Excellent - thanks for the feedback!

I've auditioned and compared the two models at home. There is a huge difference IMHO. 
To resume both have a great definition and quite same sounding in the high but with the INT60 you will have much deeper and more define bass and a wider soundstage. 
I've also found the Int25 a little bit "agressive" when you turn up the volume. I've always preferred to keep it under 30. 
This could be explained by its limitations in the bass register. 
I've kept the INT60 for these reasons.

I have the INT-25 and it is among the best amps I have heard. Integrated of course. It's silky, like velvet. Warm, rich, huge, impactful, real, and has an immensely deep soundstage and just the right amount of details. The 60, which I do not own but have heard is to my ears a tad more aggressive. Either way, beautiful amps. I do not need the power of the 60, so the 25 is magic in my system. I prefer it to the Luxman 590 AXII, Naim Nova and even a tube integrated I have here with EL34's. A true heirloom piece and IMO well worth the asking price. It's not about measurements but how my ears and heart hear the music, and this amp speaks to my heart. 

@stevehuff what speakers are you using with your INT-25?
Thanks :-)

I love the two completely opposite reviews from two people who've tried both head-to-head... and both with efficient speakers to boot.  

Just goes to show that you've got to hear equipment in your system, with your ears, to truly know what you'll prefer.
