I only buy hifi where I get the UK/EU 2 year warranty and I know I can get a repair done effectively. There are hardly any Topping resellers in the UK and the one I found (scan.co.uk) I suspect will have a good warranty arrangement with Topping (they are a large company from whom I buy servers).
I've only had three audio items break in 35+ years. One was my Chord Mojo, the usb socket, out of warranty. I sent it to them and they sent me an invoice for the repair - £0.25 for the part and £9.99 for postage. I regret not keeping the invoice!
The other two was a piece of Danish hifi, 6 years out of warranty, they shipped UK/Denmark and back and fixed free of charge. The third item was a Zorloo DAC Amir recommended, the volume button broke, which went in the bin.
