I have a good chuckle at those defending Naim etc against the HiFi Rose RA520, often citing 'service concerns' etc. That's the usual excuse. But often established brands leave customers floundering when it's time to service, time and time again. That excuse becomes flimsier day by day, as is the obsession with being made in China. Naim produces in both UK and China. Get the hell over it.
To a newcomer with disposable income, the HiFi Rose on paper concedes nothing to the equivalent Naim Uniti Nova Power at over twice the price, with both having Class D amplification, or slight variations thereof.
And here's at least one good review of the RA520,

I would pick a Naim product (or other UK company including Cyrus) over something built in the far east any day of the week, not because the product is necessarily better but because I have faith that the product can be repaired beyond the warranty in the UK, as yet I haven't seen that with products coming in from China, Korea and the like.
Here's an example why although it's not HiFi based
I have a rather nice Japanese camera, pro spec, I bought in second had with less than 1000 images being taken, the cameras are renowned for their reliability and expected to last for around 300K before issues should arise.
The camera failed, it couldn't be sorted in the UK so went to the European base instead, they couldn't sort it so it ended up having to go home all the way back to Japan, six months later I was told that it was fixed and would be returned to me, that took another month. I was lucky that I had a second camera I could use but that probably wouldn't apply with a failed HiFi unit.
Thankfully all the costs were covered under the store's warranty, but my point is that to fix this issue, my product from the far east had to go home, what is the set-up for HiFi Rose, where do their products go if they need remedial attention?
A lot of companies have links with the far east, I have products that are built in China or assembled with parts that are produced in China, I'm not anti far east products I just have more faith that when I swipe my card and put my pin in the £3500 or so that I am spending on HiFi is going to last me a long long time and not end up in a year or two as an expensive doorstop if I buy from UK companies.
In the end where you or I spend our money and on what is immaterial as long as each of us is content with what we have purchased.
