@smodtactical I've been using SET tube amplifiers for 20 years and this is the first solid-state amp to have a beautiful enough midrange to sway me away from tubes while the added weight and heft in the bass region from the XA25's high damping factor provides a solid foundation to any music. It's an excellent combo and I highly recommend it. Vocals are velvety smooth, string, and wind instruments sound amazingly dynamic, natural, and very real. I highly recommend this particular model over other XA amps in the line up for its unique minimalist use of 4 high output transistors per side, exceptional specifications when compared to all the other XA series, and its specific distortion makeup which, to my ears, comes closest to a SET tube amplifier.
