Has anyone here compared how R4 sounds vs R5ii in class A mode?

How does R4 compare purely sonically with R5ii with Class A turned on both devices?

What's the best and safest way to clean the jacks or holes on Hiby R5ii? Contact cleaners are safe? Compressed air cans? Or are they best left undisturbed?

The thing is I already have changed the cable. But what is bothering me now is that I have already charged hiby with that 5.2 voltage charger twice. Hope it has not damaged anything internally. Just played music on it

So even a 0.2 difference in voltage bad for charging?

Using a 5.2 v 2a charger for the hiby R5ii(5v 0.5a). Hope this is not bad for the player. Can anyone shed light on this?

Wondering if there is a different burn in time for the balanced port vs single ended on Hiby R5ii? Have played around 10 hrs on single ended now. Sound is delicious via HD 650.

Thanks. I got anxious about damaging the inner amp section of my hiby R5ii. After using the faaeal cable on 4.4 mm output, somehow the single ended on r5ii sounds little less louder like 3-4 volume steps which could also be my placebo. Balanced sounds the same. I guess a damaged dap-amp will...

If an amp inside a dap like Hiby R5ii is damaged then won't there be a drastic sign of that? As in the dap will totally stop working or sound awful or does a damaged amp degrade gradually or in a subtle way that is hard to even tell. After I used the cable with my hd 650 the single ended sounds...

I have a Hiby R5ii + a Sennheiser HD650. Recently bought a Faaeal 4.4 mm balanced cable for hd 650+hiby r5ii. While it delivers more power and loudness, it does sound a bit shouty or harsh compared to single ended. I just wanna know whether this faaeal cable is genuinely a balanced 4.4 mm cable...

But don't fake balanced cables damage the amp? Just wanna know whether I bought a genuine balanced cable or not.

Recently bought a Hiby R5ii. Ran it with my Sennheiser HD 650 single ended class A. And it worked very well. Then I just tried a Chinese 'Faaeal 4.4 mm balanced cable' with my HD 650. Since then I have been feeling that the Hiby R5ii sounds a little less loud just a narrow bit only on single...

If something like the hd 560 can run via ab economy then the R5ii can easily juice my hd 598 via single ended class a I guess. And maybe it can juice hd 650 via balanced class a
