Warning: China-Hifi-Audio.com

But my guess is the original owner backed off RE-selling the amp to chinahifi.
so chinahifi was caught in themiddle
this is my hunch.

@mozartfan -- there’s a bridge in Brooklyn that I want to sell to you. Please PM me asap. I only take cash by the way. Once I receive the cash, I can send you pictures and other non-essential details like the condition of the bridge, not that it matters when buying bridges.

Why don't you just buy from a Local Dealer. Line Magnetic Stuff is shipped from China and many of the items are old discontinued or back of the factory products that have not passed quality control properly and are not fit for export. 

Update from my my last post. Yong Lee from China HI-Fi did reach out to me on 5/6/21 to inform me that R8 amp would ship out between 5/10 and 5/20. Apologized for not replying sooner.
Amp shipped on 5/18 and received UPS Worldwide Expedited tracking number. I received amp on 5/25/2021. UPS delayed delivery by one day. I received amp double boxed and well protected. No damages, I set up amp, I used my own tubes and not the Wellsington tubes. I’ve been playing the amp for the last 4 days and it sounds great. Overall, my experience was positive and would purchase from China Hi-Fi again.

With Amazon Prime, it seems the safest bet, is to go with near zero risk. 30 days to try the product and not more than 40.00 to ship it back. That is the experience I'm having with the 100LBS Muzishare R100 300B 805 currently running up my electric bill. Coming off a Theta Dreadnaught, my jaw is on the floor at the sound that is coming out of this thing. Your milage may very as its not getting a fully flat single and is being high passed at about 100Hz into powered subs on Vandersteen Quatros, but still. IMO, it is very much worth the slight risks you take with your money, but Amazon has a pretty iron grip on their vendors, nearest I can guess. Ive have the same experience with Chinese DACs as well. Absolutely insane hw good they sound at any price.

Why are you folks still buying junk made in China? So many companies in China are deceptive. You can buy other equipment that is as good or better from more trust worthy sources. The government is the problem, their influence on the people and all industries is troubling.
