Echoing what Bill B wrote- This is a most excellent review.

Being fairly good friends with Wayne, I found your characterization of him to be spot on. He is as humble and down to earth as it gets and you couldn't meet a nicer person.

I'm delighted to see his human qualities recognized and represented so eloquently. When he told me he got this cover, I asked him how many print copies he was getting and he humbly shrugged it off as only he can.

Now I'll have to see about organizing a personal demo of the XP-30 wink

Great review of a really well engineered product.

As the happy owner of both an XP-10 as well as an XP-20 I must admit music seems to be more involving and enjoyable since I've got them in my systems. Maybe it's the Pass Labs house sound or maybe it's simply the passion that their designers put in making those products.

Pass Labs products always seem to have soul...'s picture

With all due respect: Why on earth would anybody put a capacitor in the signal path. What if one has an amplifier with a low impedance input. The 600 ohms graph looks very much like the high pass filter of my speakers. Not in the XP-10, not in the XP-20 and not even in the Xs. What is goin' on in the XP-30...?
