Cayin A 300B

Anyone experienced the Cayin A 300B amplifier?
It's a beautiful SET using the 300B tubes and I'd like to have some opinions about this amp.

Hi migueca,

Not sure if this will help much but I own a Cayin A300P, the sibling to the 300B.  So similar except a push-pull design with two pair of 300Bs and output of 20w.

Based upon mine I consider Cayin products to be very well designed and built.  With that they represent great value in the world of 300B amps.  Mine drove Cain & Cain BENs and produced a wonderful, musical midrange.  They were great down to the upper bass, a little below 60 Hz, but I attribute the fall off below that to the speakers, not the amp.

So I moved on from that system.  I tried the Cayin with my hybrid Janszens but it does not have quite enough power for a wide range of music, that includes big band and symphonic.  Mine is now unused so I should get rid of it, but I consider it a great amp when matched with the correct speakers.

Thanks for your comment Pryso. 
I also own a Cayin - the MT 45 Mk2. It's also a push-pull using KT88 valves. 

Like you said, Cayin products are precious gems. Build quality, design, the small details and of course the sound. Everything excels!

I live in China, near by the place where they are made. Together with Line Magnetic, these are the greatest "bang for buck" I've ever seen. To get the same quality on other brands, one would have to pay much much more (especially here, where local products are so cheap).

I bought my amplifier one year ago and the choice was conditioned by my budget. In the same shop they sell all the Cayin line and also the Line Magnetic products. At that time I fell in love with the Single Ended from Line Magnetic, but money issues pushed me to my more modest Cayin. 

Now my situation changed and I'm planning to move to a SET (I really prefer the SET sound). I intend to go to the shop again to audition 3 amplifiers: the LM 518; the LM 219 and the Cayin A300B. 
There are many articles and opinions about both LM amplifiers, but only one review about the Cayin SET (from Stereophile).

The ride to the shop takes me one entire day, that's why I'm trying to get more opinions from people who have experienced this Cayin. 
But in the end it will be my ears deciding, with all the three amps lined up for an audition. 

Thanks once again!
I am also a great fan of Cayin products, great sound, great value.  I own their tube integrates. Also, the VAS line, sold by the USA distributor is great, I own the mono blocks and the Citiation 1 pre-amp, which is a knock off of the classic HKI, updated with SOTA parts.  Both I made by Cayin . I have had Marantz and McIntosh tubes and Cayin/Vas have better sound.  Cayin approach is to take classic tube design and marry it with SOTA parts and sell at reasonable price.  No need to revent the wheel.
I believe the same, Coolhunter, no need to reinvent the wheel. Cayin products prove that a classic approach works great if you put a lot of care and the best parts together. I'm very happy with the quality of my small Cayin and the sound is also great. But I do prefer single ended to a push-pull. I will happily move to another Cayin amp (the 300B) if it stands up against the Line Magnetic SETs. 
I own a Cayin 688R. Only one in the world I think. 
I have owned the Cayin A50T & while they are fine products IMO the Yaqin MS-300C is every bit as good an amp,almost identical build/parts quality & less $...
I'd be interested to hear what rrfrerichs1950 thinks of the 688R, and what tubes he uses in it. The ultimate tube integrated - with a tone control no less.
