double DAC conversion while using 'analog in' and 'analog out' in Connect

Hello everyone.

I wonder if Sonos Connect does the DAC conversion of analog signal, that comes in to the device, and then do the conversion again while sending it to 'analog out'?

I think it does and I look for a possibility to use Connect as a preaplifier but without double conversion?

I need to plug in hi-end CD (with better DAC then Sonos) to power aplifier and would like to use Sonos as a preaplifier but without loosing quality.

It is possible?

I was under the impression that later Connects (after about 2011) may no longer be bit-perfect if you use the volume control.
The issue was that even without the volume control -- in Fixed Volume -- later CONNECTs were found to be not bit-perfect if normalisation tags were present. (Clearly with volume adjustment the device isn't bit-transparent anyway.)

Thanks for clarifying.

So, however old the OP's connect is, he's not going to get bit-perfect output if he uses the Sonos volume control. Doesn't really change the comment about using a pre-amp, then.

The issue of bit-perfectness is irrelevant anyway, since the OP wants to go analog-in and analog-out. Bit-transparency only relates to digital output, derived from digital content delivered via the network (and conceivably via PLAYBAR's optical input).

My mistake - I assumed that the only reason that the OP was going to buy such an expensive CD player was that they cared about quality - otherwise, they could buy any player if it was just for convenience. The proposal is that the OP uses a pre-amp, in which case why wouldn't they use a digital connection?

Because HiFi pre-amps conventionally don't have digital inputs. That's what an outboard DAC does. And in any case the CONNECT doesn't have a digital input, only PLAYBAR does. I'm not sure where all this is leading....
