Had a Holo May KTE L3 and now use a DAC200. Measurements aside, the DAC 200 is subjectively on a different level, particularly when fed DSD (upsanpled via HQPlayer) The preamp is excellent and it’s fully balanced throughout. Just a great piece of kit for the $$$.

Maybe, but a $10 bus powered USB hub actually makes the 3.0 work. There is no added power input involved to the hub or Intona. Can’t figure that one out.

You are able to get an Intona to connect to the Red? If so, is it an Intona 2.0 or 3.0? My Intona 3.0 won’t connect to the Red unless I put a USB hub in between.

From my experience somewhat closer to none … hope you can find a resolution.

I am trying to figure this out as well - if the USB type B port can be used for any other purpose outside of Holo RED OS DDC redirection eg. Flirc IR receiver with Ropieee OS or Bluetooth receiver for Rooextend OS or attached disk as per your case .... (with a type A or B adapter likely). (An...

If the jitter/delay is so bad that the dac’s usb buffer overflows then it will be clearly audible as a small pop/click. There’s no grey area here. Electrical ‘noise’ is the part that seems to be more up for debate.

After some initial struggles, I have found a happy place with the RED streamer ... a) RoPieeeXL with RoonBridge and NAA. Seems a bit more stable than RED OS and no tiny dust pops so far with DSD 256 via NAA/USB. Guessing that RED OS is still a work in progress and hard to know how much has been...

So I was able to get the RED -> Intona to work by putting a mini USB hub in between them. Apparently an AQ jitterbug or iFi iSilencer will work as well so I might try one of those to reduce cable count. I was also able to the get the NAA 4.3.0 RPi4 image to run on the RED after adding the...

Just to be 100% certain, are you running an NAA image on the RED or just have NAA enabled in the RED OS? I assume it's the latter.

After some further listening time, I am having trouble discerning much difference between the RED OS NAA vs dedicated NAA Intel mini-pc, except that on occasion I get a light pop from the RED like dust on vinyl. As per prior posts, this implies the occasional USB outbound packet loss (125µs). I...

Yes it's frustrating. I use Roon -> RAAT/RoonBridge when doing multi-room playback ('party' mode?) and Roon -> HQP/NAA when doing single system critical listening in my primary room. So what I do is run RoonBridge via SPDIF to my DAC, and HQP/NAA via USB to the same DAC. The Holo RED can be...

To a degree. If USB, you have to remember that, unlike Roon, HQP NAA locks on to a USB device/output and doesn't let go when music is stopped, so the USB output is not available to other sources until HQP is manually shut down. (My only gripe with HQP). (Can't speak to Spotify Connect). With...

Good idea but as far as I know, the Aux power on the intona feeds the isolated/output side of the Intona, and is separate from input side. The Intona can connect to an input without having an output/dac connected to it. And that has it's own handshake protocol that one can observe via the green...

Thanks for validating. Quick impression is that my UP Gateway running NAA image —> Intona —> DAC is clearly better than RED OS NAA —> DAC. Not surprising I suppose. Shame I can’t test RED —> Intona —> DAC.

Just hooked up the RED to my system and it doesn't work with the Intona 3.0 (7055-C) from the USB output in streaming mode. The Intona just can't connect properly to the RED - it flashes and makes a ticking noise at 4Hz (indicates "Full Speed" 12Mbps transmission as per Intona doc but the...
