So the last couple of weeks I have done some binge listening and found myself time after time in audio Nirvana. Unbelievable what this little gem is capable of. Rob Watts must be some kind of genius to say the least. Now, 3 weeks later it’s time to do some cable and other stuff tweaking.
In my post a few weeks ago I promised to test the effects of polarity on my DAVE and last Monday I’d planned a power-cord (and interlink) listening sessions, so I also had the opportunity to listen carefully to the influence of polarity on SQ. I more or less repeated these sessions yesterday, just to be sure that the results didn’t got influenced by listening fatigue or other external factors.
I used following music to determine SQ:
Dire Straits – Fade to Black (from “On every street 16/44.1)
Benjamin Clementine - Winston Churchill’s Boy (from “At Least for Now” 16/44.1)
Nils Lofgren – Keith don’t go (from “Acoustic live” 16/44.1)
Miles Davis – Blue in green (from “Kind of Blue” the 24/192 Mark Wilder remaster)
Deadmau5 – Seeya (from While(1<2) 16/44.1)
Led Zeppelin - Since I've Been Loving You (from Led Zeppelin III (Remastered) 24/96)
I plugged DAVE directly into my Mirror Image mono amps on the RCA inputs, driving my Revel Ultima Salon speakers via Van den Hul The Third speaker cable. Since this is a headphone forum I also used a pair of Audeze LCD-3s.
Just to be complete, I also tried connecting DAVE to my Mark Levinson pre-amp, both XLR and RCA connected, but running DAVE directly plugged-into the power amps does wonders for me.
Rob Watts expected for me not to hear any difference in SQ when changing polarity and I will be the last to doubt him, being the kind of genius his is. But respectfully I have to tell I was very surprised to find out that polarity indeed has it’s influence on DAVE’s SQ. Not in extremes, but rotating the power-plug indeed did something in warmth and also in placement of voices and instruments. It all sounds a bit “cleaner” and more precise.
Another thing that surprised me was that power-cable quality also has it’s influence on SQ when changing polarity. When I used the normal out-of-the box cable I could hear SQ improve a tiny little bit, but when using the cable I ended up buying (WireWorld Silver Electra 7) I could clearly hear a difference in SQ when changing polarity.
I don’t know if every DAVE is wired the same way powerplug-wise, but for my device I have to connect the “live-wire” to the top pin for best SQ.
So to sum things up, YES for me polarity has it’s influences on SQ, even with our beloved DAVE.

p.s. I ended up buying the WireWorld Silver Electra 7 powercord. I also tested the Platinum version and this one is even better. For me the 4x higher pricetag kept me from buying it, but it took a lot of self-control to keep me from buying the Platinum.
