New Network Acoustics eno2 system

[agisthos]

I have the SmoothLAN and it works nicely.
The ENO 2 seems to be the next step up on the upgrade path.

It would be good to hear from someone who actually has the ENO 2 and had used products like the EE-1, iFi or SmoothLAN and tell us what is gained.

Compared to iFi or SmoothLAN you will experience a more natural sound quality. It gets you closer to the original music. Definitely worth the upgrade.

you will experience a more natural sound quality

…because more details in the recording are revealed with eno2.

For clarity, this isn't relevant to ethernet (and the title in frame 1 is highly misleading). I confess that I flipped through but most of the Q&A were about the data reaching the DAC. It is the streamer which converts ethernet data packets to a continuous bitstream and it is only at and after the (any) streamer that timing (and jitter) become relevant. Comments about the shape of the analog(ue) signal used to carry digital data risk misleading folk if a clear distinction is not made between pre-streamer digital data (in packets, asynchronous) and post-streamer digital data (continuous bitstream, synchronous).

I don't know your setup but the effect of Ethernet connections are easily audible in a setup. That's why users hear differences between Ethernet cables, when using a switch or different switches or in this case Ethernet filters. There are many users here too that have an extensive experience over the years in their setups like @luca.pelliccioli etc.

I'm obviously in no position to tell people what they did or didn't hear; none of us are! What I'm questioning, with my statement in bold above, is the attribution of what people hear to the factors that make that occur.

The differences amongst ethernet cables and ethernet switches, clearly audible to anyone with a decent system, are purely in their effectiveness at reducing or eliminating the RFI noise they permit to reach the streamer (and from there the DAC where it does its mischief). The streamer takes the asynchronous data packets which reach it and completely rebuilds and reclocks them into a continuous bitstream, so discussions of analogue shape or of timing/jitter in the ethernet domain are irrelevant to sound quality. Post-streamer is a completely different world and all of this stuff makes sense there.

I totally agree. Its the RFI and high frequency noise from fast switching hardware that is riding down the network. This noise pollutes the ground, or rides on the signal wire itself. Galvanic isolation works in a limited band and does nothing to stop this high frequency noise. And its not intended to.

Nothing to do with timing, waveform, jitter e.t.c those things just open the door to attacks by sceptics because its obviously wrong.
