Pass INT-30 or INT-60

I have the Pass Labs INT-60, First Watt F7, and The HP-1 headphone amp. I do think jdoris gives a good summary of the INT-60 amp.


I have found all three amps are significantly improved with replacing the original fuse with a Synergistic Research Blue fuse. The results are not trivial. Within 24 hours the sound is improved and it continues to improve over the next 10 days. There SR fuses are sold with a 30 day return for refund . Plus if you have never looked under the hood of these amps this gives you a good excuse to see the wonderful workmanship Nelson's team accomplishes.

How can one use a headphone amp with the INT-60 since muting it also mutes the preamp outs? (Assuming the speakers are not also playing!)  

I own the INT-30 and drive a pair of Focal Sopra No. 1s without issue.  Volume is plenty for me in my 12’x15’ room.  The Sopras are rated at 89db@1W.  Again, more than enough power for me

@melbourneguy what’s the difference between the Accuphase e-650 and e-470?

I own the Harbeth SHL5+ powered by the Accuphase e-600 and i've never been happier. It's been about 3 years now. I haven't heard the Pass but I've heard good things about it. I got a deal on the Accuphase from a friend who owns a shop (it was a demo). It's an amp I never ever thought I would or could own because they cost (to me) a ton of money. If you live anywhere near Rochester NY I'd be happy to let you listen. I melt like butter every time I play music through it. I'm sure the Pass would do the same thing. It's plenty of power for me but I've reached an age where I listen to music in a different manner than I did 30 years ago.
