Good product the Audio-GD DI20HE, is a very good DDC and a good improvement over the Singxer SU6.

I purchased this amp after I have had many other amplifiers. None of the amplifiers could really drive my speakers. Except for this amp. Its rather fantastic! Sound is much crisper and more agile than any other amp I have tried (and some were much more expensive too!!) The power is insane and sound is unbeatable. One "downsite" is its heavy! Next thing is a new dac, the R7 it will be! Thanks Magna.

This is a good amp for the price. Can easily compete with amps up to at least 1000 euros. Sound is more engaging and enjoyable than the good, but more sterile Topping family competitors. Thing I noticed is that the front switch doesn't really turn it off (it still keeps drawing about 3 watts), with the back switch it turns really off. Also this on/pre/pha switch can cause serious DC offset peaks, at least on the XLR-outs, which can be a serious issue with certain power amps driving speakers (Singxer needs to be turned on first and turned off last to prevent issues). Not sure if this is only my unit (btw I didn't put jumpers on the power supply protection circuit).

For a long time I have read that Audio-gd R2R DACs are transparent, organic. I bought an R2R-11 direct from Audio-gd and I was surprised how great it sounds and with the build quality. Recently I bought an R8 MKII and some other Audio-gd gear from from Jos and Rob. I was impressed with the build and sound but I wanted to live with the DAC for some months before making a declaration. At this point, I can say I finally get it when people say these DACs are organic. I have several other midrange DACs (Oppo 205, Brooklyn DAC+, RME) to compare this one to. The R8 MKII is the only one which disappears all the time. It's transparent, I feel the music for the first time as natural without hearing the gear at all. The RME has come close at times, but only on certain recordings. The R8 MKII just disappears and it's the closest thing to a live performance I have heard out of my system. For the price, I am extremely satisfied with this DAC. I had a strange problem with noise over AES, coax, and optical which did not occur via I2S nor USB. I was unable to explain it sufficiently to Kingwa at Audio-gd so I reached out to Magna Hifi and Rob quickly recreated the issue. He contacted Kingwa on my behalf and I think only a week went by before I got new firmware which resolved the issue. I cannot imagine getting this level of service from another shop or DAC manufacturer. I have 4 Audio-gd components and I can recommend Audio-gd and Magna to any lover of music. Audio-gd gear is quirky but to me that is part of the charm. The build is industrial, reminiscent of 60s and 70s garage-fi but on a very high level of sound quality. I noticed that the LED displays of the R8 MKII, the DI-20, and Master 19 amp are all slightly different colors! This is annoying in a darkened room but in normal daylight it was not noticeable. Other than that, the dimensions of the gear and the brushed finished on the panels match well. Clearly, the R&D and manufacturing money has been focused on sound. Tank-like builds, heavy gear, you feel the quality as well as hear it. Jos and Rob are easy to work with, they're friendly and responsible and run a good business.

Wat een fijne versterker, muisstil, zwarte achtergrond. Super veel details, erg mooie plaatsing van instrumenten en artiesten. Superstrakke basweergave. Speel met een Meze 109 pro hoofdtelefoon. Had hiervoor een creek obh21 hoofdtelefoon versterker maar dit is zo een grote sprong voorwaarts dat heb ik niet durven dromen. Vragen werden snel serieus en eerlijk beantwoord. Kortom heel tevreden.

Nice bass reproduction, nicely layered! Deep stereo image and the authentic class-A sound. Well done for the money!

I compared DI-20HE with Gustard U16, strongly modified Singxer SU-1, Singxer SU-6. Definitely Audio-GD is the best among them. The best structure/order on soundstange (feeling that everything is corret compared to another devices, sound is the most natural), great resolution and sounds are the most filled. Worth to spend money on it, better to wait and buy it.

Bought the R28 2022 version: what a purchase! I regrettably no longer have the HE6SEv2 and I bet this beast would drive those as a charm. The DAC portion of the device is also very satifying and it took me a bit to get uesed to it (brain or hardware burn-in? I will never know...). Coming from a Violectric V200 I thought I was akready enjoying a warmer than average sound delivery but this takes it to another level. I have yet to decide if I prefer NOS or OS. The effect of the vynil record simulation, which is suppposed to provide the smoothest setting, isn't yet clear to me and I don't hear much of a difference. Using it mostly with HD800S and Arya Sealth Edition. It also proved an outstanding match for my Beyerdynamic T90 whos high register is less extreme with this amplifier than it is also with a (modest) tube amp such as the Little dot mk III, which I am now selling. Indeed it seems that the same sonic results of OTL tube amplification can be obtained by the R28: not sure if it is just due to the R2R decoding or if also the amplifier plays a role. Great service from Magnahifi is the icing on the cake.

4 letters : OMFG, i'm speechless..... As expected, the DIHE20 (not burned in yet ofc) is putting the 7.77 in non reached level so far......soundstage is huge, and bass are so perfect....... Just a little black side sound, the DIHE20 must burnin i suppose TY Jos!!

Straight out of the box the Serene pre-amp sounded fantastic and as a bonus the XLR1 out used as a headphone amp sounded also very nice. An incredible improvement over the the Audio-GD M1 pre-amp. Much bigger difference than I thought it would be. So far I'm really happy with the pre-amp! :-)

GREAT !!!

I had a standard DMP-A6 but was allowed to trade it in at Magna for a MASTER edition. My wife didn't know (yet) that there was a different model of player. :-) Today she said that she could notice that such a device apparently has to settle, because she said: 'last night you were listening and for the first time in the past two weeks it finally sounds very natural!' Hmmmm. I just explained what I did and then we laughed about it. But getting back to the common question “is the difference noticeable and worth the EUR 400 it costs more?” YES!! 1000%

The Singxer su6 tagled your equipment up to a much higher level. Especially if you're playing with a Nucleus, Nuc or Rhein z1 you certainly have to meet this sensational SU6 . Stronly recommended i’ve you like timing; rythm and refined heights. I’ts you’re number One choice.

I love my Holo Audio system. They now have had the required burn-in and they sound fantastic. It a major upgrade. Thank you for the great support.

This device sounds really great to me, a big improvement, much more than the SU2 alone! But in combination it is really nice

Absolutes Highlight! Für diesen Preis unschlagbar. Von der Benutzeroberfläche bis zum Sound, hier ist einfach alles top.

Using those headphones I learnt the meaning of "sound definition". I think quality is impressively high given the price! 10/10!!! Also, exceptional service from MagnaHiFi! I think I will buy also a proper DAC to have the full experience

I doubted for a long time whether the ESS DAC would not be the analytical one for me. Jos assured me that this is by no means the case with Audio-GD. Finally ordered and now a few weeks in my possession. I listen through my Audeze LCD-2. Wonderful combination! Tight and deep low and sparkling high with voices that are rock solid. Thanks, great purchase!

thx for fixing my problems !! EVERYTHING sounds beautiful with my headphones now ;-) Very fast support...you make it! Outstanding service.

The EverSolo has arrived and it's really great !

It is outstanding DAC. Sound quality is amazing. I use R28 NOS as DAC/preamp with Nelson Pass’s amplifier Aleph J connected via XLR output. I also satisfied with service of Magna Hifi.

The DMP-A8 is great. I absolutely love it :) I also bought a DMP-A6 a few months ago from you, but this DMP-A8 is a real beast. Much better sound.

I am really impressed by the sound quality, with my Hifiman HE1000 stealth it is incredible to hear each single instrument separated, placed in its black sphere and each sphere placed in the lateral space and in depth. It is a truly holographic representation and the leap compared to my Hifiman Serenade is evident, in the next few days I will try it with all my other headphones.

Great audio streamer with unprecedented possibilities that performs well above its price in terms of sound.

I currently have an Aqua La Scala DAC, but decided to buy an Audio GD R7HE MK3 for comparison. The result is that I like the sound of the R7HE MK3 much more, and so the La Scala goes up for sale. The R7HE MK3 is a really good DAC. Many thanks also to Magna for the good service.
