Any thoughts on Pass X150.8 ?

Sonically I wasn't crazy over the 150.8. Build quality is fantastic but overall the midrange was analytical and boring. The bass was very good and highs were also however,  I could never warm up to the amp. Was using with Sonus Faber Olympica 3s which were recommended for the 150.8.  Ultimately went back to tubes and very satisfied.  

@koslekt1 How does the Diablo 300 compare to the Pass amps you have auditioned?

I had a 150.8 briefly; then compared it to the 250.8. I found there 150.8 not tremendously involving- power was not the issue. I found the 250.8 much more involving and have owned that for 7 years now. It's a forever amp. 

I bought x150.8 but then upgraded to x250.8 before taking delivery of 150.8. Why did I do that? I don't know, but I read x250.8 is the sweet spot of Pass line ups.... Will see when my amp arrives.

@panerai557 without a doubt good move.
