Triode Wire Labs 7+ and 8+ Power Cords (7 and 8 gauge respectively).
This is not a full review because I have not had enough time to do one due to problems with both my DAC and amp. However, I did get to listen to both cords for several hours; the 7+ on my amp and, then, the 8+ on my DAC. For several days prior and in the hours leading up to the switch, I had been using a pair of 8 gauge Purist Audio 20th Anniversary power cords ($2500 list each) on the equipment, that a friend had lent me.
The Purist, compared to my own cords (which are only 10 gauge), were explosively dynamic and effortless in presentation. They had a lower noise floor and a deeper soundstage.
The interesting thing is that the TWL cords, at a fifth of the price, matched the Purist in dynamics and effortlessness. They did not have the really deep soundstage that the Purist did but the latter, in comparison, sounded a bit too forward for my taste. Soundstage on both was wide and tall. The Purist were more incisive (sharper transient attacks) and separated individual lines better but the TWL overall sounded more coherent, of a piece.
What is more, and of utmost importance to me, the TWL cords produced a greater harmonic richness/tonal density, without being veiled or muddy. The end result being that, in my system, I preferred the TWL 7 & 8 Plus to the Purist 20th Anniversary power cords. This is an amazing achievement for TWL.
Edit: Yes, I bought them.
