Aurender N20 vs N200 with a Berkeley Reference DAC 3 and Berkeley USB Interface Box


The Aurender N20 OCXO clock pushes outputs to the DAC (unlike asynchronous USB where the DAC pulls info), but only on the AES or BNC outputs. Supposedly OCXOs are much more accurate and stable than the temperature-varying crystal oscillators (like the one used in the Berkeley USB interface)? Additionally, the N20’s upsampling only works on the AES/BNC (not USB) output.  So, is it better to use the N20’s AES or BNC to connect directly to the Berkeley Reference 3 DAC, or use the N20’s USB output via the Berkeley USB interface box? I primarily listen to MQA and Redbook files via Tidal/Quboz.

 

  1. If better to connect the N20 directly to the DAC via AES or BNC, are there any other features of the N20, that make it better than the cheaper N200 (I have no plans to use an external clock)? What are those features?
  2. Is the USB output better or the same between the N20 and N200 units?
  3. Is there a difference between the N20 and the N200 in the way DSD is handled (played natively vs FPGA conversion)?
  4. Does the N200 have the All-Digital Phase-Locked Loop system (ADPLL), or does the ADPLL only work on the AES/BNC and not the USB output?

I have an Aurender W20SE and have used a Berkeley Alpha Reference 3 … I found the AES the better connector. 
 

On the other hand, I preferred the Audio Research CD/DAC to the Berkeley… but by such an incredible narrow margin it was negligible (although $5K extra for the Berkeley was not negligible.

Berkeley DAC’s are designed and optimized for AES/ SPDIF digital interface. So I would feed this DAC with a streamer that is just as meticulously designed to complement your DAC i.e. N20. I used to own N20 :-) 

@dciraldo I am an authorized Aurender dealer. The N20’s OXCO clock is a very high quality one and is worth using. You will get the best possible results sonically from you unit using it. Luckily your Berkeley also prefers an AES input, it should be a no-brainer to use this protocol over USB.

The N20 and N200 seem to have similar quality USB outputs, but it doesn’t mean the two units will sound the same. Everything factors into the sound of each unit, and with the much improved power supply and isolation the N20 offers, the sound quality of the N20 is considerably more full, tonally rich, and less-fatiguing over time in a considerable way… not that that the N200 is in any way a slouch - it is still impressive at its price range.

Aurender units can also play DSD natively or converted to PCM (using FPGA conversion to DoP format). This happens both in the N20 and N200.

The phased-lock-loop feature you inquire about is only for SPDIF outputs of the N10, N20 and N30SA as it is tied to the Aurender’s internal clock. This is unavailable with with N200 due to clock differences. Using USB completely disregards the internal clock regardless of model.

I have both the N200 and N30SA on hand for demos, and the performance of the reference N30SA is simply jaw-dropping. Feel free to reach out directly should you want to discuss Aurender units more deeply.
