Pass Labs Int 25 vs Int 60

I'm curious if anyone has had a chance to listen to these two integrated amplifiers.

I know the Int 25 is basically the XA25 with a preamp. The Int 60 runs class A to 30 watts (and uses the same preamp) so maybe it's more closely related to the XA30.8, though I don't believe I've read that anywhere.

Anyway, I think from a power perspective both will be fine with my 90db floorstanders. My main question is which is the warmer, smoother of the two amps? Even if that means being darker and more veiled, I would want to go with that amp!

Thanks.

Also, the int-25, for me, has the all out best bass performance of any integrated I’ve had. Bests the Luxman and any others I’ve had. Makes the naim pieces sound thin. But the magic lies in the mids with the 25 and Heresy.  Nothing harsh about it with the Heresy IV, no matter how loud I go.

@stevehuff Really great comparisons in that review Steve.  For people who haven't clicked yet, Steve also has top-quality integrateds from Luxman, Vinnie La Rossie, and Line Magnetic on hand for comparisons.  What a privilege to have those in the stable... all beautiful in their own way I'm sure.  And really an accomplishment for Nelson to have come out on top...

@stevehuff Great review of the INT-25! Being class A, how warm does it get? Thanks.

I haven't read the review yet, but I can pretty much guess what it says. This is by far the best, bar none, amp Steve has ever heard. This is it! The end game, the final stop!

Give him 6 months and you'll hear about Pass Labs shortcomings when the next 'end game' amp shows up. :)

@bluorion With any Nelson Pass design you should assume it'll get pretty warm.  I think his general rule is to keep it around a level where you can keep your hand on the heat sinks for about 5 seconds before being forced to pull away.  I've had an XA-25 in my room, and it wasn't crazy hot, but I don't think you'd want to stuff it in a cabinet or anything.
