I have heard both and had the Cayin at the same time as the Almarro. I love my lush sounding and plenty powerful Cayin. In comparison, the Almarro has wonderful slightly superior midrange, will require very efficient speakers if you like to turn the music up, even a little and lacks in the bass department.
With my reasonably efficient Spendor S8e floorstanding speakers (I found them more efficient than most monitors), I could not get enough oomph to play the music with any authority at all, and I don't mean trying to play loud.
The Almarro sounded very weak. Only low level volume, almost background music, could be played. The Almarro requires highly efficient speakers made to be played with low power amps, then of course your bass may go out the window and you will need a musical sub.
The midrange (albeit only playable at low levels and weak) on the Almarro is wonderful and has the edge over the Cayin which itself has some of the best most lush midrange I have heard. However, the midrange is only part of the spectrum. If you like to turn your music up and like good bass that extends into the midrange, the Almarro is badly lacking in all but rare speakers with the highest efficiency.
All things considered, I personally prefer the highly musical Cayin A-88t and the flexiblity of speaker choice that comes with its power.
