Expert 200 BlueSound / Sonos latency

[thumb5]

Hello @el_pedro, and welcome to the forum.

[Edited after I checked my e-mail archive...]

I used to use this kind of set-up with an Expert in one room, and a Sonos in the neighbouring room.  It worked fine, with no noticeable latency.  Actually before I bought the Expert I asked Devialet what the latency was from digital inputs to speaker outputs, and this was their reply:

The latency between digital inputs and audio output depends on the sampling rates. It goes as follows:

Fs (kHz)   Tpd (ms)
  44.1       5.0
  48.0       4.6
  88.2       3.4
  96.0       3.2
 176.4       2.6
 192.0       2.5

 (It is approximately equal to 138 sample periods + 1.8 ms for all sampling frequencies between 44.1 and 192 kHz.)

Bear in mind that this was back in 2011 so things may have changed since then as the firmware has evolved.

Back in the day, Devialet were very responsive to that kind of technical question. Nostalgia sure ain't what it used to be...
