PASS LABS XA-30.5 vs XA-60.5

Hello all,
Has anyone heard the differences between these two amps, and have done A/B comparrisons on them? I have a XA-30.5 that I'm using with Totem Hawk Speakers. The XA-30.5 drives them very well, but I have been told the 60.5’s give you much better smoothness and cohesiveness, better imaging, better bass control, greater ease and greater resolution.

Here's the million dollar question:

I am ready for my next upgrade and have roughly $6000. Should I upgrade to the XA-60.5's or upgrade my Esoteric X03-SE cd player to the Esoteric seperates P-05 transport and D-05 DAC??

I have very appealing offers for both options.

Any Thoughts?

My system:

Pass Labs XA-30.5 amp
Pass Labs X0.2 preamp
Esoteric XO3-SE cd player
BPT 3.5 Ultra Sig. power conditioner
Totem Hawk speakers
AudioPath custom IC's and speaker cable
Shunyay Python CX power cords

Interesting Roor. Other than more power, I did not find the XA-60.5 significantly different than the XA-30.5, and in fact I found the XA-30.5 to be the smoother of the two amps in the highs and mids. There was no veiling from either amp.

Probably comes down to different associated equipment and speakers used by us.

With the Esoteric X-03SE single box player, I could not tell the difference between these two amps. As soon as I moved up to the Esoteric P-05 and D-03 I tried the shootout between them again, and it was an improvement that wasn't subtle. The XA.5 amps take a LONG time to burn in properly, which is critical. I had similar results to your comparrison early on, but once the 60.5's had about 300 hours on them, they really came to life... much smoother in the mids and highs. Hope this helps.

I had my XA-60.5 for nearly two years, and I ran them seven days a week, sometimes 10 hours a day. The XA-30.5 still sounded better in some respects in my system.

Nevertheless, it's good to know you have arrived at something that satisfies you.

With speakers friendly to both amps, I hear very little difference between them.

Perhaps the XA-30.5 is a bit more polished.

Dealer disclaimer.

I've talked with other Pass dealers who hear the same improvements I noted above, within various systems. I also did a/b shootout with several audiophile friends listening and we all came to the same conclusion without question. The 60.5's are better all the way around...
