Pass Labs 350.8 or 260.8 ?


I ‘m using a ARC Ref 6 per-amp with my Wilson Audio Sophia 3 speaker now. And I’m planning to buy a new amp to replace my old Electrocompaniet AW-180 Mono this year. My target is either Pass Labs 260.8 Mono or X350.8 stereo. Some of my friend encourage me to get 360.8, but someone said 260.8 has better analytical, more details and imaging.  On The other hands,  maybe I will upgrade my Sophia 3 to Sahsha 1/2 in next year.   So, will 350.8 is a better choice for long-term because it can drive Shasha better than 260.8 I guess?  But my concern is 350.8 is too heavy, I'm unable to move it. So which amp you think is a better choice for me ? My listening area is not big, about 220 square feet (About 9' from my ear to speaker).  And I only listen to Jazz music, especially U.S. and European contemporary Jazz. thx.

I think for jazz, the XA series is probably better. The X 0.8 series sounds faster and has more slam but I would think the XA 0.8’s excel in every other way so it would depend on what you prefer.

The X 260.8 are mono’s right? They will take some heavy lifting too.

There is a lengthy thread here where the OP goes through many amp permutations and he reviews the the X350.8 as well as some XA 0.8 mono's, with a combination of pre's and speakers. i think he is currently on the ARC Ref 10 and some Wilson's so it may give you an idea.
