Hey Blake,
I’ve had the N30SA even before I became an Aurender dealer, and I’ve had a lot of time to dial it in. In summary, streaming is now my primary source, even over local files.
Further upstream, I, too started with an EtherRegen, which made little noticeable difference. I started the upgrade by adding a Farad Super3 linear power supply with a very good aftermarket power cable to power the EtherRegen, and to my surprise, the performance improved more significantly than just the EtherRegen on its own.
A number of months later, I unfortunately fried the power supply due to a stupid mistake in using it on another piece of equipment. Rather than replace it, I decided to try using the Synergistic Research Ethernet Switch UEF. What an improvement it made, even over the EtherRegen and Farad LPS. Presentation was smoother, more effortless, while improving on clarity and dynamics.
I had already been an advocate of Synergistic Research for about a decade, and I became a dealer for them in spring of 2023. One of my first purchases of demo equipment included the SR Router to build on to the switch. The Router had a different effect, improving harmonics, density, and liquidity to a point where it started to sound like I was listening to master tape. I’ve continued to build on that chain with no regret, and honestly, for some reason, I truly believe that streaming signal sounds better than some of the high resolution files stored in my Aurender. Part of this is likely due the exceptional management of electromagnetism that SR is known for.
My chain today, for reference:
Netgear Orbi Mesh Satellite
SR Atmosphere SX Reference Ethernet
SR Router UEF
SR Atmosphere SX Reference Ethernet
SR Ethernet Switch UEF
SR SRX Ethernet
Aurender N30SA
SR SRX AES, Coax and USB (for demo purposes to different devices)
I also now use the Aurender MC10 master clock, which further improves the clarity, focus, snap and texture. It makes a difference on the N30SA on its own, but it’s even better if you have a DAC or other digital equipment (eg Theoretica Applied Physics BACCH-SP) which can take a master clock.
