Quick question for R-28 owners using balanced headphones: is the locking mechanism on your 4-pin XLR connector very stiff? Mine seems to get stuck in the ‘open’ position when I connect a balanced cable, and doesn’t spring back into the ‘locked’ position unless I gently force it back into place. It seems to be loosening up a little now with continued use but is still very stiff.

On my friend’s NFB-1, the push tab was very springy and loose, as it should be.

Edit: nevermind, I answered my own question. Seems the connector itself was just screwed in a little too tightly. Loosened the front screws and out it popped. Might just put a very thin spacer between the connector frame and the R-28 case to keep it loose.

Red is always right, so where you see the red analogue connectors, that’s the right in/out, and therefore the white connectors are the left in/out. So if you’re looking at the R-28 from the front, right in/out is on the right and left in/out is on the left. (If you’re looking at it from the back, as in the photo below, it’s the opposite - right is on the left, left is on the right).

The optical In 3 is a bit cricket O.O... triggered.......

I cracked open my R-28 today to have a play with NOS modes and PLL. Will report back on my findings once I've had a proper chance to digest them (and to troubleshoot some minor issues I discovered). Meanwhile I took a bunch of pics of the R-28's internals, so thought I'd share some quality Audio-gd porn with you!

PS. This has to be one of the most gorgeous pieces of equipment I've ever had the pleasure of owning (or shooting). Enjoy...

@gLer AGD should ditch their R-28 pics and use yours. Nice work.

They’d be welcome to them, for a small kickback of course

This unit should be sold with see through top only ,nice picks g

Do I need to install specific ASIO or WASAPI driver for Win10 (JRiver MC) to use R-28?

From my experience, you need drivers from https://amanero.com/drivers.htm for ASIO. You may hear the sound difference after installing drivers as well.

@gLer That's just obscenely good-looking engineering right there. Puts many so-called high end (read insanely priced) gears to shame.
I notice AGD now use branded TCXO clocks.

Looking forward to NOS impressions.
*Smashing pics btw...

Oh your picture is so beautiful

Thanks.

Just put my order in. Expecting great things!! I just sold my Auralic Taurus MKII. Hopefully the R-28 can deliver as an exceptional 1 box solution to clean up my office desk a bit.

Congrats! I have no doubt it will

How does R28 compare to NBF-1AMP+R2R-1 combo? Anyone conducted a test?

Hi. According to Kingwa they’re identical. I was going to buy the ‘stack’ until the R-28 was announced. Haven’t tried the R2R-1 myself but conducted an A/B test of the R-28 and the NFB-1 and they were virtually 1:1.

The NFB-1 has a slight advantage of more inputs/outputs if you need them, while the R-28 has the advantage of true low/high-gain (+7db and +17db) while the NFB-1 only has one (high) gain (+16dB) with ‘high-gain’ mode reducing the number of volume steps from 99 to 64 (although actual ‘gain’ is unchanged).

The R2R-1 has the advantage of being able to change OS/NOS modes from the front panel, but is otherwise identical to the R-28 dac section.

Bottom line: they’re essentially the same but the R-28 will cost you quite a bit less and also take up less space.

One minor correction here: The gain for the NFB-1 can be customized while ordering. I believe the options available were 0, +3, +9 and +16dB. Don't quote me there, but the info is on the product page. I went with +3 I believe and have had zero trouble driving my 560's and barely use the volume at all (12 in low gain mode) to drive my Clear's.
