Thanks for this review. I bought a unit after reading this, and it sounds great. It is powering at set of Dali Rubicon 8s in my living room.
In my opinion this combo disrupts my previous system (Dali Rubicon 6C) for stereo use. Because you get very similar features and probably less total harmonic distortion, as well as less dynamic compression for about the same or less total system price.

2x Dali Rubicon 6C = USD 10,000
1x sound hub + BluOS module + HDMI = USD 2,050
Total: 12,050
OR
2x Dali Rubicon 6C = USD 10,000
1x sound hub compact (no BluOS) = USD 450
Total: 10,450 | 2x Dali Rubicon 8 = USD 10,000
1x Powernode Edge = USD 650
Total: 10,650 |
Amplifier
THD+N = around 0.002% at 1kHz, 1W into 4ohm (upto 0.005% at other frequencies).
Loudspeaker
THD = unknown, but Rubicon 2 had its highest distortion below 800hz. The additional woofer in Rubicon 6 happens to cross over at 800hz.
Based on a design with 88.5dB (2.83V/1m) sensitivity
System frequency range: 37-30,000hz
Maximum SPL = 110dB (manufacturer's number) | Amplifier
THD+N = below 0.004% at 1kHz, 1W into 4ohm.
Loudspeaker
THD = unknown, but must be lower than Rubicon 6 at lower frequencies and higher volumes. Still much higher than the powernode at 1W I assume.
Sensitivity: 90.5dB (2.83V/1m)
Nominal Impedance 4 ohms (measured 4.1-19ohms, 10hz-50khz)
Frequency Range: 38-34,000hz (however the powernode is -3dB down at 30khz)
Maximum SPL = 107dB (my assumption based on 1x50W from powernode edge) |
Due to the digital crossover, the C-series needs two amplifiers, and one power supply in each cabinet. I guess the amplifiers also need to be +200W to accommodate for scenarios where the loudspeakers are used outside or similar. This drives up cost. However as I am using the Rubicons in a small room, the powernode offers more power than I will ever need.
I wish the economics stacked up better for Dali. Because at least in theory, digital crossovers should always be superior. Especially if done for all drivers (unlike the 6C and 8C which are both hybrids). Would have loved to see it offered properly with the
Dali Kore and
Epikore loudspeakers just as a statement.
If I ever get the Epikore 11s, why not power them with the Powernode Edge?
