Allnic A-6000 monos

Curious if anyone has any experience with the Allnic A-6000 monos. I'm looking seriously at these amps. Curious if they have the dynamics compared to a 845/300b SET amp like the Line Magnetic 219ia or Cary 805AE's.
I have had a pair of Allnic A 6000 monoblocks in my system for around 3 months and I love them.
They happily drive a pair of Quad 2905s on the 4 ohm setting. The texture, weight, dynamics and soundstage are all excellent .
I have no experience of the other amps yon mention so can't comment on the comparison - but I wouldn't be looking to change my A6000s for anything....
