Chinese integrated for around $1k

Thanks for the responses.
There are no distributors of Chi-fi where I live (Israel), so this is going to be a blind buy while holding my fingers crossed (online search teaches me there are no known reliability issues).
I contacted the Dussun owner and he has agreed to ship directly to me either the V6i or the V8i (once it gets back in stock).
The V8i and the Shengya are similarly priced for me.
Since my speakers have ribbon twitters they need a healthy power amp behind them. I currently power them with Tag Mclaren r100X5, and they must be bi-amped to produce something that resembles their potential (I auditioned them with MASSIVE Krell monoblocks and fell in love on spot).
I am wondering whether the V6i will do the trick or is the choice to be made between the Shengya and the V8i...

Both are OEMs for well known western brands (Vincent & Red Rose), the Shengya just looks better cosmetically, but I'll have to buy via Aliexpress or Cattylink (which charges and arm and a leg for shipping and handling fees)

Cayin 265i is only 40wpc. I don't think that's enough to drive the Vollas. Is there any other integrated model by Cayin that might fit?
As for Jolida, I'll research them as well.

The Lina Magnetic Audio is nowhere near the power requirements of my speakers (the ribbon tweeters make them power hungry).
38w just won't do the trick.
I hope the 150w of the Dussun V6i will, but am not sure.

I have an option to purchase localy a used ATC SIA2-150 or a BMC C1, either one for around $3k/
Given the shipping the shipping costs and the taxation on the Dussun, this is about $1k difference between the options.
What do you say, are they even comparable?
