Great system you have. I have owned Pass amps for 40 years… most recently the X350.
I would definitely go the XA100 route. You get a more natural musical sound. Which after many years of pursuing greater and greater slam and detail I realized kept improving those attributes but taking away from the musicality (rhythm and pace, midrange bloom) and naturalness of the sound. I now have a Audio Research 160s… more similar to the XA
However, you are not me… if you are headed down the route to Magico then maybe your interests lie in detail and slam. In this case the get a Pass X350… seriously don’t fool around with the 250. I had the choice and my dealer pushed me towards the 350… I never regretted it.
