Hi

It is recommended to use an external linear power supply of 2.5A and above.
12 to 15 volt，More than 15V is bad and may damage the device.

3A is ideal, 5A is even better.

With more sufficient linear power, you can hear a more stable, more energetic, and more fulfilling sound field when playing music.

We once tested the 1A power supply and the AH90 could not start.
So there is no need to try an underpowered power supply even if it is less noisy.

Hi, I'm also totally into this!

Did anyone test the UPnP feature for stability, quality, etc? What files and sample rates are supported with UPnP?

In my understanding, UPnP streams the source file (i.e. .flac) as-is to the device and thus allows for bit-perfect playback, but only up to a certain bitrate. It should be possible to set this threshold bitrate in the UPnP .config file. As the OS is Debian and the firmware update mode 'exposes' the file system via USB (as @GUSTARD said), I wonder if's is possible to adjust the UPnP quality settings.

Another question I have is if the USB port features ios-otg compatibility (plugging an iPad for stationary Apple Music playback)? I asked the Audiophonics support and they mentioned it should work but maybe someone can confirm this.

Thx!

The UPNP protocol of current streamer firmware version（1v43） support PCM 44.1-384kHz without any problem.

In addition, the USB input supports Android and Apple OTG

@GUSTARD what is status of "DSD Direct" mode for AH90 ?

Is it Close to release?

Many of us HQPlayer NAA and Roon RAAT users are really excited for this firmware update

I hope the process to update is easy

I hope it still allows selection of the AKM DSD filters

Exactly
I’m not buying one until this is firmware is updated.
If they want to sell these they would hurry it up lol.

I also hope it is properly tested so that it doesn't have the initial A26 problem with "DSD Direct" Mode

 

[camrector]

Agreed.
We can be sure that Jussi will put this through its paces.

no guarantee he will buy one

He might.
If not I’ll send him one!

Hi all, does the Tidal connect work on android? and if not, will be it possible in near future? I ordered R26, will come in two weeks, I suppose, that the streaming section is the same by R26?

 

[Ilan spiro]

Hi all
Can someone here can confirm if lps cable connector is 2.5 or 2.1??
Thanks

Ok, so I received the unit today and got it working via USB with the Gustard USB driver. Is this the latest revision?

I didn't receive a paper manual, I guess the PDF and driver are on the small CD that came with the unit. It's 2023, can the product have an official page with drivers and manual? I have 2 PCs and 3 laptops in the house but no CD drive.

Edit: Also Tidal Connect doesn't work from either of my phones, it sees it in the list but when I selected it doesn't play on it. Works with mconnect and bubbleupnp. Gustarender says 1.43.

Thank you @GUSTARD

I am quite interested in this Audalytic streamer-dac.

- Is this unit compatible with LMS (logitech media server) bridge upnp/dlna?
- Does it have gapless function playing over upnp/dlna?

I ordered my H90 tonight. I am confident that this will take care of the quality issues regarding converting streamed content. I am not expecting it to top my Moon CD-1 which Burr Browns with over sampling. Not only that, but I am giving serious consideration to the eventual purchase of a Ladder Bach Preamp, unless someone can tell me why that is a bad idea.

Aldo look at Gustard P26 + Sparkos ss2590= OMG
