DevialetArch Phono Stage - Enhance Your Vinyl Experience - Exceptional Sound Quality - Seamless Connectivity - Wireless Audio Streaming

I am an owner of a pair of Silver Phantoms which are really great. But if you wish to connect external equipment that are not Bluetooth enabled, you'd be left with hoops to jump through to make work. Such was the life if you wished to connect a turntable you already owned. But Arch fixes that problem, although at the additional cost.It is quite expensive at $350, but the Devialet products are far from economical to begin with.Fortunately, all is forgiven once you use Arch. I am using Arch to connect my Marantz TT-15S1 turntable to my Phantoms and it has been working fantastic. It has been very stable, and sound quality from the built-in phono stage is excellent. In fact, I can really appreciate vinyl playback again compared to digital lossless files...the Phantoms really let you hear the difference between formats. Lossless sounds very good, but Vinyl almost holographic at times.Bonus points that Arch allows you to connect "any" RCA/Optical equipped audio source easily to Phantoms.The only nitpick I have with Arch is you need to use the Devialet app to change the Phantom input to Arch. It works fine and is easy enough, but it would be most convenient if the button on Arch can be used to simply select Arch as the active input. Currently it serves no such function.Overall, Arch is a great solution if you wish to add external audio gear to your Phantom ecosystem. I believe up-to four Arch can be connected at this time.

The item is apparently a used item but it was never mentioned in the description.

Installation is very easy, the sound quality is excellent, but there is about 200ms of latency and there is no way to turn off the power.
