power supply fore sure... same goes for Mainboard, SSD and RAM.

very transparent product development blog over more then a year since that swiss company stopped make precursor models and a 40+ year Hi-Fi shop owner followed up. Had someone make a dedicated power supply for it.

If you are familiar with Linux(Debian) and Windows - and Network in general. PM me. I will assist you. However if this is new to you, do not bother unless you are have the courage....time.

I am testing my new server SAN right now. Aswell as I am overwhelmed, aswell I know there is no unit that can handle every genre. This also goes for source/streamer...sorry to drag you in to this rabbit-hole...its nit-picking zoomed in

 

[OCC7N]

@OCC7N iscsi it's too old protocol and very fragile. I would rather check for newer ones...
Now, I'm not into streamers at all... Maybe in the future..

That is the point...no security, pure sound....what do you have in mind? -> please no mention of NFS/SMB/CIFS(Rooooon) or the ordinary ones- > with securities/handshakes that degrades audio immensely!

Fragile is what you want! -> but running behind a firewall! -> with strict rules

Please challange this thought - old is gold! -> I will take the challange, I want to be proved wrong

Ohh diretta? -> ipv6 -> nothing new under the sun

I expect you tell me what the new protocols is about, I mean it

I got you on this. I was =4

I will send you a pm because I find this very of-topic from audio GD or audio in general.

I really don't understand this, sorry.

The reason I do not find this off topic is because it eliminated masterclock LHY OCK-2 and also made me think backwards -> towards source of power rather than moving away, by powerconditioning sonics into locked/influenced presentation.
1. Noise/Power tweaks in playback/streamer(target)
2. Masterclock/LHY OCK-2 -> better flow, stream
The finding of all this is power/perfomance measured PSU works best on digital network units(around target/streamer). It is so good that internal powersupply(of the streamer) becomes a preference rather than a matter of measurements for perfection

Putting iSCSI storage on 10G fiber connection solved 2 problems:

1. Noise/Power tweaks in playback/streamer(target)
2. Masterclock/LHY OCK-2 -> better flow, stream

- a normal fmc fiber connection will not solv the same problems. iSCSI is the key!

So are you no longer using the Ock-2 at all in your chain. I am a bit confused by what you wrote? Are you using any masterclock?

It is always good to have a sanity check.

Went to head fi these days and was very impressed by higher end dacs and amps (unlike previous years).
Back at home, I am missing something in the music.
Compared D28 to my very first dac/amp and if you take away the connectivity and only hear fhe sound… very close if not the same. What… After having Audio GD on top of my list for years, I am actually puzzled and need to explore more…

As I continue my Audio GD journey, I have some rather unexpected revelations to share:

1. I have completely abandoned ACSS connection and use only XLR cables between the DAC and the AMP. ACSS doesn't sound right to me anymore.
2. I increasingly use SE connection for headphones with my HE9 Mk2. Surprisingly it sounds better / more natural than the balanced one with all my headphones (use mostly the Susvara stock SE cable now, which is quite decent). Initially, I was led to believe that the balanced connection was always superior.
3. I no longer use external clock for the DAC, only for the DI20HE.

I guess what I'm trying to say with this post is that one should never hesitate to challenge his initial assumptions, no matter how well established they are.

I'm also interested in this topic. Specially since the GD equipment I've got have already regenerative power supply.
I wonder how much filtering is going to be a step back increasing resistance.
I am pretty sure that best thing would be something like a surge protection with voltage control. Not sure if Furman Elite-15 PFi or Elite-20 PFi are what I'm looking for but it seems like the best fit.
Any suggestions?

Thanks in advance

I have noticed no difference using power conditioner on Audio-gd HE gear. Dedicated mains spurs make a big difference ideally separate spur for every audio component including router

No I have the Audio-gd D28(ESS 9038Pro) which works great that way, the background is L/ess polished - clean …. ->It is more darker, saturated, textured, tangible.

Upscaling is a trend that has huge following. I am satisfied with my sound, and never felt the need to change anything but the cables/source components.

I think the advantage of upsampling is moving noise out of audio bands particularly treble. At 44.1k sampling frequency the roll off filter is working very close to audible band. PC upsampling is OK but Grimm does it far better from my experience.

I wanted to know which all-in-one device has the same DAC as their well received "R-7HE MK3". So I asked Audio-GD this:

Which among R-28 MK3, R-27 MK2, R-27 RE, R-27 HE has the DAC that can be compared to "R-7HE MK3"?

Their reply:

The DAC of the R-27MK2 is equivalent to the R8MK3
The DAC of the R-27RE is relative to the R8HEMK3.
The DAC of R-27HE is between R8HEMK3 and R7HEMK3, so the DAC of R-27HE is closer to R7HEMK3. The R7HEMK3 has two more CPLD chips than the R-27HE, handling I2S and coaxial and AES signals respectively.

I am surprised how inconsistent they are in their information.

I got “The DAC part of the R27MK2 is similar to the R8MK3.”

Anyway, prices just went up insanely. Magna raised R27 mk2 with 500 euro these days to 2.7k. There is no information of any hardware or performance changes though.

Sorry, in which way inconsistent?

My bad. I misread the previous post as R28…
