Aurender


I have a Korean car, watch KDramas and even listen to some KPop, but I don’t get what Aurender is doing.

I’m currently in digital hold given that my new Holo DAC died, but intend on listening to my IFi Zen stream and look at upgrade paths.

Some of the most respected members of this forum swear by Aurender, so it must deliver, but here is my point of confusion:

1. Coax and AES are the preferred outputs, but higher bandwidths require dual AES out, but I don’t have dual in on my DAC.

2. Aurender’s top models claim to have great clocks, so why not pass this on to the DAC via I2s?

3. Top Aurenders accept external clocks and I assume this is used with a DAC that accepts external clocks, but why bother when I2s would take care of this?

4. The argument against I2s is that there isn’t a standard, but this isn’t a problem in most implementations.

I’m sure that I have misrepresented things above, so please correct my understanding.

Pink Faun has developed fully customized OS called Euphony Stylus. The end users can switch between Roon and Stylus depending on one’s preferences in playback quality and UI experience. You can also add Merging Technologies +player to above list. The implementation of ROON in their +player is just as remarkable not to mention the adoption of RAVENNA which allows streaming upto DSD256 over Ethernet.

The Suncoast Audio video was informative. They clearly stated that streaming services, streamed internal and NAS are processed and sound the same. All files are loaded to cache and played locally from cache. Given that some of you can hear a difference suggest that some difference in background processes must exist.

They clearly believe that the N20 is the sweet spot, but that the N200 is the best transport value for USB only. The choice depends upon how your DAC handles USB vs coax/AES.

All of the transports, except the battery powered W20SE have been updated within the last couple of years.  All now have transformer isolated ethernet inputs and the newer lower powered Intel chipset.

This video was a really good Aurender sales presentation.

@lalitk Nice to know about Euphony Stylus on Pink Faun. I recall when Euphony first came out there was a lot of chatter about how it sounded better than Roon. I have one friend that still uses it, but I never personally owned a hardware solution that ran it. Thanks for sharing. 

@vonhelmholtz Yes, while the streaming processes and protocols may be the same, the quality of the power supply, clock l, and isolation in the design of the circuits and components (isolation overall by chassis, isolation inside across individual components, etc) are the main reasons why each unit sounds the same. 

@blisshifi 

Just to make sure that I understand..The better clock is integral to providing the ultra low jitter Coax/AES output, but is not central to USB output, thus for USB only the N200 is sufficient.

My replacement Holo May DAC KTE will be here on Wednesday. I’m interpreting your post to say that AES/Coax vs USB performance is very close With the Holo. If this is correct, then USB would certainly provide you with the added ability to listen to high bitrate PCM and DSD, but given the fact that you are struggling with interconnects, my interpretation of your remarks might be off.
