Aurender

@baylinor Apologies, in most posts I do mention that I am an authorized Aurender dealer. I missed it this time. That said, I purchased my N30SA prior to becoming a dealer. Sometimes I prioritize being an audiophile first and was not intending to promote Aurender and try to make a sale. Vonhelmholtz and I have had many discussions personally, and I was simply responding to him directly. He knows I’m a dealer, as he has purchased from me in the past. 
 

@vonhelmholtz FWIW, yes the higher end Aurender’s have better clocks, but as @oddiofyl states, even with the N200 he prefers coax. I did not sell him that unit, but I did provide his coax cable.

Also, I meant to say +1 in support of a master clock. My T+A unit already has a masterclock built in, and does not accommodate any external clocks, otherwise I’d be looking at one myself!

Just to make sure that I understand the terminology used. When purchasing a high end Aurender with a high quality clock, does this singly describe the stability of the clock, or are there other factors that contribute to the "high quality"?

Fairly new Aurender user here.  Have the N200 in a speaker system and the N150 in a headphone system.  Use an Android phone in both with absolutely no problems.  Sound is glorious in both systems.  Could not be happier that I upgraded.

Not limited to Aurender, a high quality clock is usually one using OCXO or Femto and “quality” is about accuracy of timing, just like a luxury watch that uses a mechanical design to keep time. The clock’s role is focused on the transmission of digital samples and how well it assembles those samples back together. I wrote in a different thread, but clock and digital playback accuracy can be compared to photography. Many cameras and lenses can take a photo, and many of them do it “well”. But some stand out because of the quality of the lens in reproducing exactly what is out there, and the image is crisper, more natural, and the colors do not bleed due to aberration. A great clock does the same and results in the most accurate timing of digital signals, which will result in clarity, separation, and coherence. A lesser clock can still reproduce well, but in comparison to a great clock, it’s as if the image just wasn’t properly focused ever so slightly, or a slightly inferior lens was used. Sometimes one cannot tell unless comparing the two photos side by side. 

Higher end Aurender’s do leverage better clocks, but they also leverage more robust power supplies, better isolation (both in circuit design and chassis), and other benefits. 

I just put a 4 TB SSD drive in the N200.   It is amazing what that machine can do.  I turned it on and there was another icon in the menu.  The TD100.  Its a USB trigger for the Aurender to turn on 2 trigger enabled devices .   

When I picked the unit up and pulled it out of its rack I was quickly reminded of the quality of the Aurender.   It is built like a tank.  Pics don't demonstrate how nice these units are.
