I'd like to A/B a Matrix against my Fryette Power Station.
Done that. I used a Matrix for years, since the original XT800, thought GT800 and GT 1000. I recently got a Power Station,and have just sold the Matrix.
The PS does have a slight coloration perhaps - but not much. It is designed to be neutral - like a HiFi Power amp. The biggest point for me was the low mids. I felt - compared to real amps - the AFX/Matrix Combo got a little congested in that area. This may be due to the extended low freq range of the matrix, or the flat low mids - which on the face of it should be ideal - but it did make it hard to get that attack. The PS did it right with no messing.
The Matrix is louder (or at least louder before the PS starts to compress and saturate) - but the PS is roughly the same volume as my 50W Fender Machete combo so its not quiet. The PS is relatively light for a tube amp at 7kg - not too much more than the Matrix 4kg, though if you want to rack mount the PS you need a kit (more cost) and at LEAST 2U space (Fryette recommend an empty space above the PS for air flow).
Horses for courses, and its maybe my "guitarists need to change" more than not being happy with the Matrix - as I said Ive used them longer than anyone - literally as I was the first user for anything other than the XT800's original purpose as a line array driver. Im happy with the PS - but would have been happy keeping the Matrix as well.
Im my AFX time - I used an Art SLA initially, and there nowhere near the Matrix standard in tonality, dynamics or build. Im sure a quality SS Power amp (haffler or equivalent) would be just as good - but there generally 2-3 times the price, at least 2U and heavier. The Matrix is the best SS product due to those reasons. Ive also used a VHT 2/50/2 - and the PS gets the same punch, but is more neutral (and the 2/50/2 is pretty neutral as it is).
There is a comparison vid somewhere:
