Got my new speakers last weekend, Dynaudio Contour 20, which gave me a reason to stop playing with my office rig (RME ADI-2 Pro + Dynaudio Lyd 5 + Roon) and finally set up the living room system.

Here is a vid of the Contour 20 being broken in with some Daft Punk (visual purposes only, mic was just iphone mic at close range):


And here is more of the same in slow motion:


As part of this new system, I've massively reduced complexity, shed excess components and interconnects, and enthusiastically embraced software defined audio.

The whole living room system consists of:

Speakers: Dynaudio Contour 20
Speaker Cable: Canare 4S11
Electronics (dual-mono, amp, DAC/ADC, preamp, phono, EQ): Devialet Expert 400
Digital Cable (connecting the 2 units of the Devialet): Belden 1505F Coaxial Digital Audio Cable
Ethernet Cable: Belden bonded pair Cat 6
Mesh Network: Linksys Velops

That's it for the digital side of the house.

In the photo you can also see a turntable under construction (Michell Gyro SE). When it's all done being built, it will feed directly into the Devialet, no phono stage necessary, where it undergoes ADC, with DSP RIAA curve, and software definable dynamic loading variable on the fly at play time.

What's particularly cool about this setup is the integration between Roon and the Devailet, which is bi-directionally integrated. For example, chhanging the volume on the Devialet remote changes it in Roon, and vice versa.

You can also choose where you want to do your DSP:
Devialet: SAM (speaker bass phase EQ), RAM (DSP phono on the fly), basic PEQ / tone control, digital crossovers
Roon: full convolution

You can even directly stream DSD over Ethernet without having to use a separate DAC, renderer, or PC

Things I might do next (after break in):

1. Disconnect the passive crossover in the Contour 20 and use the Devialet crossover capabilities to go full active with DSP crossover

2. Add some IsoAcoustics Gaia III feet to the Dynaudio stands (spikes on tile on suspended floor isn't great combo)

3. Add a sub (although not sure I really need it)

Comments and questions are welcome.

Added new Gaia II feet to the bottom of the Stand 6 today. These things are pretty beefy, really well made, and the concave nature of the foot leads to a suction cup like effect on our tile floor.
