MU not Moo. Silent Angel love German cities and rivers. Their current model names include Bonn, Munich and Rhein. Until recently the Munich M1 was their top streamer. Now it's been displaced by the Munich MU, the upgraded offering. In ancient Greek Mu was the alphabet's 12th letter spelled Mµ. It apparently derived from the Egyptian and Phoenician words for water. Should we expect a fluid sound? MU is "designed for ultimate sound quality". That means a 6-core processor, quality clocks with a 10MHz¹ input to step up to the Genesis GX. It means a "radar-grade" switching power supply with option to bypass it with an external 12VDC linear supply like the companion Forester F2. It means Sabre silicon, high-capacity NVMe SSD storage and again the mobile VitoOS Orbiter app capable of indexing libraries up to 10TB. The rear panel is self-explanatory. Add PCM 768 and DSD256 USB support, 4GB RAM and up to 4TB of SSD storage.

¹ With the Genesis GX offering 10MHz and 25MHz clock outputs, some punters will wonder why the MU only takes 10MHz. The answer could lay in where this clock BNC sits; with the outputs not inputs. Perhaps Silent Angel feel that for D/A conversion not network purposes, 10MHz is preferable? This stuff is getting very esoteric and way above my paygrade.

To go whole Taiwanese hog like a bowl of Lu Rou Fan, I transferred a few select music folders onto the Z1+ to access via UPnP over Audirvana. I also moved the triple stack onto my Artesanía sidewall rack. That put the GX clock within easy reach of both server and streamer. Now the signal path was Z1+ ⇒ Munich MU, both externally reclocked by GX and Z1+ accessed and controlled over my LAN to stay with my hardwired protocol. The MU's built-in DAC replaced my usual Laiv Audio Harmony so a 6m XLR cable connected it to my active analogue crossover with precision volume control. Obviously one could eliminate Z1+ and use MU's own SSD for music storage. That would save considerable funds. But with Z1+ as the company's arch angel server in our crib, laying it on thick seemed the best course of action. Full pork ahead. Whilst I popped MU's bonnet, the insides showed little. A small chamber contained the switching power supply whose main guts seal inside a metal box. The larger chamber was topped by an inverted black circuit board blocking the view on what's beneath. With zero gratification for a part fetishist doing the unrobing but plenty of heckle room over half-empty chassis, I didn't even take a photo before the lid went back on.

After outing a bad network cable as culprit for baffling invisibility, MU appeared on the LAN even identified by its serial #. With support for PCM 768 and DSD 1'024, the number's brigade will be happy. Below is the Audirvana Studio window in UPnP mode.

This connection proved rock steady and below we see the Mayan step pyramid of largest GX topped by smaller MU topped by most compact Z1+.
