Do chinese tube preamp/amp clones interest you?

Wow...did I just say Jehova?

English being my 2nd language I do realize now the difference in semantics regarding clone, my mistake.
Let me tell you where I come from...I like to build things, try stuff out, so there is a long list of components and three "systems".

I currently feel the itch to build a balanced tube preamp from a kit. I have rediscovered the fun of soldering ;-)

Used to build main tube amps, at some point was even lucky enough to have access to a transformer winding machine, but had always thought to not need a pre.
BTW...I remember comments even back in the 80s that in tube amps there are only so many iterations, most of the general circuit design is well known since decades...but that may just be hearsay.

The search for a balanced tube preamp had me find two kits, one quickly described as a 4 channel car amp and I do not understand how that would be a balanced one (unless you tied ones ground to the others "+") or the one that I referenced to in it's completed version in the OP. 

I do not expect it to be a copy of a specific model, at least on a quick search I could not find a model with only two inputs and no tone controls, it would however allow me to connect the balanced outputs from the component upstream (dbx venu 360).

I have a Nobsound EL-34 Integrated Tube Amp
model NS 02D with upgraded tubes.
I have had no problems. It sounds great.
Point to point wiring.
Anyone have experience with Nonsound products ?

No.  It's more of a moral choice...  When was the last time in recent history a dictatorship put a million people in labor camps?

I bought a Chinese tube amp (Music Angel XD-800 MkIII) about 12 years ago just to play around with upgrading it. IIRC, it was around $500.

When I received it, I opened it up. It looked like the tech who assembled it, just put in whatever parts he had handy on his bench. Most resistors were out of spec.

Once I changed the resistors and caps, it was a pretty decent 30W Class A amp. The tube complement was 4 x KT88, 2 x 12AU7, and 2 x 12AT7. I ran Psvane KT88 and 12AU7 tubes and 50's era RCA 12AT7.

Not including tubes, the upgrade cost me just under $200 (and many hours of my time).

I found some of the opinions expressed here about Chinese Amps to be based on prejudice & lack of knowledge  rather than listening to the product. It is true a lot of rubbish came out of China , but, this apply more or less to most countries.
I am not Chinese( I am British -Egyptian & Ex Hi Fi plus publisher. My day job is Orthopedic Surgeon)
I have superb Hi Fi system ( Clearaudio Goldfinger , Acoustical Axiom & Kuzma 14 inch arms..Wafac PRT1 , Burmister, Lamm, Jadis, CJ, Audionet ,  Acostic Arts ,, Krell, BAT.. Giya -Vivid Speakers.)
But , My Pride & Joy ; AM 833 MKII 140 watt single ended of pure magic.
I have 4 monobocks. 2 monos : silver edition, RRP around 25000 US $ & 2 monos ULTIMA  of All Silver Transformers , RRP aound 50000 US$ plus. this is is probably one of the best Amps regardless of the price.
It is made in China By a Genius called Fang & the website is 
am-hiend.com. Apart from brilliant design , customer service is second to none. if you do not have distributor , contact him directly, you will not be disappointed
