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.

 I have owned the Pass int 60 and it was traded to reno for a int 250. The 60 is a bit lusher in the mids. The 250 is a bit brighter but has more detail and wider soundstage. Im not sure I could say one is better than the other. I feel is just more a matter of taste. Of curse the 250 can drive lower impedance better. Opinions are nice, but you really have to listen.

Ive owned both - both are amazing. The 25 sounds better at lower volumes but does indeed get agressive when turned up. It does not scale well. The 60 sounds great at low volumes as well but absolutely sings when turned up. Its fantastic. I kept the 60. 

I have had 2 pass with my Wilson Sophia 2 (89db min 3ohms). Very revealer speaker. Int30A (60w class A at 4ohms), Int60 (15W Class A at 4ohms). I chose the first. It’s a warm sound with necessary detail and information without being fatiguing. I’m surprised how well the Wilson drives, I guess being 4 ohms doubles the power to 60 watts pure A which is brutal, generating the pressure of a live concert. Int60: instead I feel that it has less grip on the bass and generates more fatigue. at mid vol The needle starts to move quite easily because it leaves the class A and the distortion of the class AB is heard.

I would like to try the new Int25 (pure A)

I listened to several Pass Amps (X250 X250.5 X350) and I feel that I like only the pure class A line of them.

If anyone is interested I have nude photos of both of them on my channel. @Mat_audio

It comes down to the load the driven speaker represents. 

If you want class A sound one must stay in class A. Though the XA25 or Int25 can produce greater than the stated 25 watts when needed, the amp is no longer biased in class A. Thus some of the 'sweetness' is lost. 

I own the XA25 and love it. Drives efficient speakers in a ~15'x12'x8' room.
