I am really enjoying the Mano! ULTRA mk3 It replaced the Bridge II network card in my PS Audio Directstream and it has added a ton of clarity and separation that I didn't have with the Bridge II. Not a subtle change.

I have the SR Master fuse in the Holo May Dac for a few days now.
There has been a really marked improvement in the sound quality of my system.
A blacker background, a real firm punchier bass,greater separation of instruments.
It seems to have lifted the performance in all aspects of this already fantastic dac to another level. Very surprising!

Mano Ultra mk3 Farad music streamer is the ultimate streaming endpoint for... View

I have only used it for 48 hours so far so it's not fully burnt in I guess, still it sounds great. I use it as a pure Roon endpoint and I've tested the supplied MoOde Player 32-bit v7.25 which I upgraded to v7.30
and installed the Roon Bridge, everything else turned off in MoOde. Later I switched to MoOde Player 64-bit v8.25 and it sounded even better. I also tested the Ropieee 2023.02. It also sounds nice, but I
think I prefer the MoOde Player 64-bit v8.2. I have yet to try your recommendation of the GentooPlayer, but I will have to obtain a test license first.

The Mano Ultra mk3 leaves the HoloAudio Red and the iFi Zen streamer miles behind. The Mano Ultra mk3 is even better than the Lumin U2 mini streamer at twice the cost behind, which I also have tested.

I thought I would send you some initial listening impressions after a longer music session last night.

In a word ‘Wow!’
I have ‘tested’ the Serene KTE preamp using my Technics SL 1200G turntable and some high quality half-speed mastered vinyl recordings.
These sounded even better than when played through my Schiit Freya S balanced preamp.

Both the May KTE and Serene KTE are clearly superbly designed and built products.

It was a bit of a gamble spending so much when I already had a good DAC and Preamp, but the new Holo audio gear has exceeded all expectations.

I think I now have my ‘end game’ audio system..for now 😉
Thanks you Jos and Rob for your advice and help.

May Dac = 'The possibility of.' The May DAC is here! over... View

I thought I would send you some initial listening impressions after a longer music session last night.

In a word ‘Wow!’

Any doubts I had about the May KTE’s ability to match the dynamic sound of my Schiit Yggdrasil DAC (which I loved) evaporated when I played some really well-recorded, CDs with huge dynamic range.
The sound was explosive!

I listened to all sorts of genres- Rock, Jazz, Folk, Classical..and whatever I tried, it all sounded ‘right’.

The PLL is incredible!
My old Logitech Transporter’s sound quality via BNC is almost indistinguishable from Jay’s CDT vis I2S.
A remarkable achievement.

I think I now have my ‘end game’ audio system..for now 😉
Thank you Jos and Rob for your advice and help.

I received Serene last Thursday and I`ve to say that the waiting time until delivery.
Was worth every minute.
Out of the box a beautiful peace of gear that sounded great from the beginning.
Now after approx. 80h of burn-in it impressed more and more.
Especially soundstage depth improved and the holographic sound together
with a pin-point imaging cached me. Never heart my system so good before.

I`ve also paired output 2 with my Meze Elite Headphone: you enter audio nirvana immediately.
It sounded so right, relaxed, smooth but totally transparent with perfect textured bass.
It's like being on drugs, one song after the other, never stop it – just listen to music more and more…

The R-27HE Audio-GD version is a discrete balanced R2-2R ladder DAC with... View

Something for music addicts-
I can only compare it to an Audio gd NFB 27.77 (ESS 9038 Pro) and it is better in every aspect. It has the Magna Hifi silver update. Sounds very natural and revealing, detailled, spacious and dynamic. Has no difficulties with showing the beauty of Al Greens voice or the power of a track by Slayer. I listened to Ali Farka Toure today and the Sleaford Mods and with both had the impression, that it sounds as it should sound.
I use it together with a PC as source, Audio gd DI 20 HE and a Mutec Ref 10, an additional power filter and pure silver cables.
And Jos gave great support.

This new DAC “Spring3” is the design that has been very popular... View

I received the Holo Spring 3 KTE a few days ago. Just a few hours after listening to it , I had a big smile on my face. It's a great DAC that excited me right away. In the few tests/reviews that I have read on the Internet (I unfortunately had no opportunity to listen to the Spring 3 before) was not overly reported about the device. On the contrary, my expectations were more than exceeded. I am already very happy with the DAC.

I am very satisfied with it. It has a place in the high end category. Worth the price. The music became much more focused and detailed. I had a Dac with an AKK chip. This R2R is much more analog, more natural.

This new DAC “Spring3” is the design that has been very popular... View

Wow…incredible performance. Anyone who says you can’t tell the difference between dacs once certain measurement goals are reached leaves me scratching my head.
The Holo replaced a modified Topping D90 and it was an obvious improvement straight out-of-the- box.
After a few weeks it just kept getting better. On one memorable occasion I looked up and thought, damn I’ve accidentally pushed the loudness button on the Luxman, but no, just extra proper bass had suddenly come on song.
So I immediately had to go back and start again with all the favourite CDs I’d been listening to.
And all this is plain vanilla 16/44 cd replay and 70 year old ears!
Great service…great product.

MANO ULTRA Mk III with FARAD Super3 LPSU streamer vs. Bluesound NODE (N130) streamer:
I have for some weeks tested MANO ULTRA Mk III with FARAD Super3 LPSU streamer vs. Bluesound NODE (N130) streamer via I2S HDMI-LVDS output to my HoloAudio Spring 3 DAC (level 2). The MANO has lifted the soundstage 1-2 levels higher than the NODE.
The sound textures are quite awesome with good separations between instruments ec. when playing London Grammar – music number: Hey Now or Strong or playing Agnes Obel – music number: Aventine or The Curse. The tempo, melodic and harmonic in the instruments are combined very separated and very clear and open in the heights up and down in the sound specter and in the wideness too, compared to the soundstage of the NODE. There are not huge differences, but it is very easy to hear the differences, wen switching between the 2 streamers playing the same music piece.
The MANO Ultra III/ FARAD is worth every penny and even more.

Got my new streamer today and wow what a difference. My system has never sounded this good before. Using i2s connection to my gustard r26 dac, and it sounds amazing. New details, depths, dynamic range and a lowered noise floor. Enjoying registering and discovering new musical facets in music that I am very familiar with.

Audio-GD presents the extreme of audio technology with the HE1 mk3. A... View

After initially being very happy with the sound straight out of the box, I found that it held back the macro dynamics a bit, and I lacked deep bass with body and sharpness. The resolution wasn't quite top notch either. But this turned out to change, quite drastically in fact, in the first month that the preamp was left up and running. Nowadays, I can't find anything to complain about (well yes, one little thing; se below): this is without a doubt the best preamp I've ever owned or even tried at home, and then I still had a preamp at home for test that cost about 15,000 euros when new! This says a lot about the sensational sound quality vs the price ratio you get with the HE1 -MK2 preamp. One result of this is, for example, that the preamp responds extremely clearly to cable changes - you immediately and very revealingly hear which cable has a higher or lower quality. Five stars all the way!!

However, I have a small remark, which I include in the following:

The front step's left button, on the right side of the display, has three functions:

1. Press it once, and a blue dot will appear, which determines whether you want the automatic shutdown of the display, or whether you want it to be always on. (One nitpick: it would have been nice to have two modes of brightness of the display, to switch between.)

2. Press it quickly twice, and you will get to the pre-volume function, which is intended to adapt signal sources with different output levels to achieve the same degree of volume. LEAVE THIS FEATURE, if you don't feel you have to use it, and deteriorate the sound! I feel that the sound is affected noticeably with this function - it gives a filter effect which is obvious, if you compare it with mode 9 (no pre-volume). Even when you compensate the db. However, feel free to try it and form your own opinion.

3. Press the button quickly three times, and you will enter the preamp's two gain modes: either 6 db or 16 db gain. This feature is very useful! I use the pre-stage with the 6 db mode and find no penalty between the two settings, either than obviously different gain.

All in all: a wonderful preamp that is more than worth its asking price. And, you can buy with confidence: Jos and Magna Hifi gave me great service and a quick response to all my (many) questions.

Easy, smooth and very pleasant transaction, as always is with Magna Hifi guys.

I think Bliss deserves a spot in solid state hall of fame. It has has both an amazing sound quality and an amazing character. It can run literally any headphones well, has all the necessary features and doesn't have any obvious flaws. For many it may be the end of the road in the search for a perfect solid state headphone amp. It was for me. It's a bliss :).

Seems to work well with my Wireworld Silver Sphere HDMI cable and my Holo May KTE.
My whole system sounds ‘right’ now in a way I’ve never heard before. It’s a feeling that’s similar across all input formats and musical genres. Excellent soundstage, neutral frequency response, realistic timbre, excellent micro detail, good low end drive and the blackest of black backgrounds.

I own the HE-1 MK2 pre amplifier and the Master 3A power amplifier and I can assure anyone this combi is hard to beat.
I did hear a lot of amplifiers like Hegel, Classe, Accuphase etc. but non of them can beat Audio-GD.
I use them in combination with a HiFi Rose RS150 streamer and Dali Epicon 6 speakers
Sounds like heaven!
Would be great if some hifi magazine would dare to test this brand compared to other well known high end brands.
