I must admit a part of my hesitation has been reading some of the posts here. It seems a lot of people are more into changing things to make their Taiko sound "better" than just listening to it.
Yes, I was guilty of this when my Extreme first arrived but that was because historically, I could always build a better mousetrap and I was determined to try. I tried different PCIe USB and Ethernet cards, I experimented with fiber USB, I played with different footers and shelves, damping plates, fuses, USB cables, and power cords. I played around with different software, upsampling, and even tried to tweak the OS. As for the network, don't get me started. Some things worked and some things failed miserably but the exercise scratched some important itches that needed to be scratched and gave me valuable perspective.
First, prior to installing the Extreme on my tall rack (which is a 2 person job), I needed to be sure it wasn't DOA and so straight out of the box with no burn in, with the Extreme sitting on top of my wood floor using its stock footers, using an old $200 TG SLVR power cord (because it was long enough) and a cheap 3m Pangea USB cable (because it was long enough), the Extreme already sounded better than my DIY server. This was my best DIY effort that just weeks before had bested an Aurender W20SE and pretty much everything else I had previously tried and without any optimization, the Extreme was better.
Second, as a DYIer, you realize what a joy it is to be able to tweak or tune a component such as the Extreme in a way you could never do with an Aurender, InnuOS, or a dCS Network Bridge. To have so many tuning levers at your disposal allows the Extreme to scale to different scenarios. When the disastrous Roon upgrade was released in 2020, it was the Extreme's tunability that allowed Emile to overcome it.
Third, as hard as I tried, I found I couldn't really build a better mousetrap. My efforts to tweak the Extreme are well chronicled on these pages. There are even more efforts that were not chronicled but today, my Extreme is very close to everyone else's Extreme. Emile has thought this thing through better than I can but it's not something I could fully appreciate if I hadn't tried. His USB card is the best I have heard. TAS, to my ears, is still far better than Roon. Despite all of my efforts to improve my network, for now, my preference is to listen to locally stored files (yes, I am in the camp where I still find locally stored files to sound better than streaming) and then disconnect my Extreme from the network. No more fancy switches or cabling. It has been some time since I've posted on this thread because these days, I'm not really trying to make my Extreme sound better, I'm just enjoying it. Like everyone else, I look forward to the release of XDMS and that is what is so great about the Extreme, without any extra effort on our part, it has evolved and improved, but even without it, it's very hard to complain.
