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

It would appear to me that the cases made re: balanced and single ended are generally sound, but not necessarily taking the specifics of the Pass circuitry (marketing?) into consideration:

Roor,
You've already got an excellent amp and source. I would put the $6000 into upgrading your speakers. Those seem to be the weakest link in your system.
Erndog: I agree and have decided to "pass" on the XA-60.5's for now. The weakest link is certainly the hawks, so I am on the hunt for speaks... My room isn't too big thgough - 16' x 12' x 8' ceilings so the hawks are no slouch in there.

Honest1: Yes, it sure was a big hole. I used shovels, and 6' heavy metal bar to loosen things up, and a post hole digger with extended/modified handles. It took about 8 solid hours. New Hampshire isn't named the Granite State for nothing, but I did hit small stones, clay and sand so it really wasn't too bad.
Any recommendations on speakers in the $5500-$7000 (used a'gon prices) if I upgrade my totem hawk speakers??

My system:

Pass Labs XA-30.5 amp
Pass Labs X0.2 preamp
Esoteric XO3-SE cd player

Thanks
