Cayin A-300P or 300B Integrateds: Anyone?

I have limited experience with the A-300P a Class A push Pull of roughly 20 watts per channel. With stock tubes it is pretty darned nice. Looks like a very expensive piece of gear, and it isn't. Bass is firm, taught, and so natural.
Art seemed to like the slightly pricier SE model.

I wish it was made in America, but boy am I impressed.

Zero reviews (in english) of the A-300P out there.

Anyone else spent time with either?
It's a shame, it is a great sounding Amp.
I heard the cayin 300P push pull with sonata 2's. The finest 300 tube INTERGRATED. Absoluetly stunning. The Silverline Sonatas had issues in the mids.
