WiiM Ultra + Vibelink dropouts

[d00]

Hello!

Has anyone encountered the problem of sound disappearing on Vibelink? I am writing about Vibelink because I used Fosi V3 mono, later Yamaha A-S701 and there was no such problem. My problem is that the sound jams for about a second from time to time. The sound just fades - dropout. Sometimes it will play 3 songs without a problem, and sometimes during one song it drops 3-5 times. It's strange and difficult to grasp.

I tried on COAX and on RCA. Here and here it occurs. Is it a problem with electricity? With a power strip? I noticed that when Ultra and Vibelink lie on each other and I touch the housing, it slightly kicks the current. As if there was no grounding.

I reset the Ultra to factory settings, tried other cables, disconnected from Wi-Fi, reset the router and it still happens. I started to recognise it after connecting Vibelink. I have not noticed such a problem with other amplifiers before.

Hi! I know this is a little off topic, but I'm not sure where else to ask: why switch from the Fosi V3 mono to the Vibelink? They have very similar performance and price

As somebody who owns a pair of V3 Monos and a WiiM Vibelink Amp I'd suggest these potential reasons. The WiiM Vibelink Amp ...

• has a built-in power supply, allowing for a cleaner, clutter-free setup
• consequentially isn't prone to developing noticeable beat tones when two amps are powered from different PSUs and the TPA3255 chips don't start up fully in sync
• runs noticeably cooler than the V3 Monos
• supports the use of a trigger cable
• measures better than the V3 Monos regarding load depencency, IMD and frequency dependency of distortion )as per ASR, not my own measurements)
• looks better

This list might or might not be comprehensive.

Hellol,
i had exactly the same problem , the anomaly appear after 3 week from purchasing, after many test the problem was clearly located in the vibelink . i Sent back trough amazon, and i purchased a new one . the new one is connected now with ultra with optical cable (as also suggested in some tread) and at the moment is going well.
