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

I'm still shocked no one commented on roor's electrical installation.  I'm a master electrician.   I have done audiophile installations and am very passionate about getting the most quiet installation and being safe.  roor's installation is absolutly, unequivocally dangerous and wrong on many levels.  Never, ever, ever install as he has done.  

Roor, ground your system right.  Hopefully the only person you kill is yourself.  Not your kid or his /her friends.  What you did is stupid.  

Always run a ground from the panel to your receptacle.  Never ever float a ground from an audio rack into the yard.  It's so stupid it just infuriates me.  Don't do it.

If you want to bury a copper pipe, go ahead.  But only connect it to your main bonding jumper in your panel.   Personally I drive 3/4" x 10' copper ground rods.  They are made for the job.  Copper pipe will oxidize pretty quick and become useless over time.
My comments are to hot.  Sorry about that.  But the point ia still accurate.  Never take a ground to your yard.  All to easy for it to become 120 volts at 16 amps in your grass.  Will kill anyrhing that contacts maybe a 50 foot area around it.  It will never trip the Curcuit Breaker.  Itps just a huge electric matt in your yard.  Always ground to your panel.
That's a really old post I doubt that guy got your comment I found it because I was looking Pass Labs info,  but yeah it's crazy to mess with grounding like that and like you said extremely dangerous!
