After auditioning the Qualiton X200 for a week I've made the decision to keep it. Thanks to all for your input as it was really helpful. In the past, I had a 80wpc Class AB Cayin integrated with upgraded caps which was very good. Liquid midrange, very musical, and had a relaxed presentation. If there was one critique: the bass was not as defined, quite wooly sounding but still enjoyable. The X200 is in another league, most notably in how it presents bass notes which is almost SS like in terms of tautness and definition. Agree with what was mentioned that I'm never gonna get the bass slam of an SS amp with the X200 and TBH I'm okay with that.
Where the X200 truly shines is in the midrange, making music sound hauntingly beautiful. I can only imagine what the A50i sounds like. Very pleased with my decision, thanks to all.
