I'm taking naked pictures of the amp right now.

I'll just say I'm impressed with what I've seen and heard so far.  I'll wring it out here soon.

 

Cheers!

The one I received has OPA134 (x2) with BUF634 (x2) buffering (James also sent copper bus bars).  The Dac is a Wolfson WM8740, so I believe the DAC is a significant upgrade over the XM5's PCM2704!

 

I'll be posting more soon (feeling better).

 

Cheers!

Wow! this is good news, I have the XM5 and love it. I'm using it's DAC right now feeding my little dot 2++ not bad, wonder how the Wolfson DAC would sound....

 

Did they change the battery chemistry as well?  How long between charges?

I'd love a comparison between this and the iBasso D10. 

 

Can the XM6 be used as a stand alone amp, or dac?

I actually finished listening and trying out the DAC last night...I'll be writing when I get home.

 

I apologize again for the delay.  I didn't expect to get too sick to listen to music.

Pratical Devices XM5 with BUF634+AD8065 really sounds awesome IMO.  I'm using it now with my LD 2++ acting as the pre-amp and with the PD XM5 acting as the amp and itouch as the source, it really pushes the shure se530 and UE tripple 10's to it's potential.  Hope James kept the BUF634+AD8065 rolling option in the XM6.

Yep, I wonder why OPA134 is chosen for XM6. I would think they should have made the AD8065 or AD8610 as default this time.

You can still get the 8065 OpAmps from James at PD...

True, but OPA124 is about $1.10 (1Ku) while AD8065 is less than $2. With an adapter it should still be around $5. It should well worth the effort to put it in XM6 since it will be PD next flagship. If it is AD8610 (almost $9 by itself) then perhaps the cost will be higher, but then again we are not talking about $100 amp here.

Part one of the review is added to my first post (the thread title has been changed as well)...

 

Looks like this is going to be in several parts.  I will attach part two soon.

 

Cheers!

 It does make for a suspenseful review, doesn't it?
