I started my journey on higher end ICs with Iconoclast TPC interconnects. Great value for the money. I used them on source components and from pre to amplifier. They were a huge step up from the sub $100 ICs I was using at the time.
I wanted to upgrade beyond that and contacted Iconoclast. They happened to have a great deal on a UPOCC RCA cable and I decided to give it a try. While I don’t recall every detail sonically between the TPC and the UPOCC, there was yet another big step forward in quality. More open, more detail, bigger soundstage - I could easily hear the difference between the upgrades in grades of copper.
At the same time, I was also in touch with ZenWave to try Dave’s newest D4 cable, which is pure UPOCC silver. Yes, a bit more expensive than Iconoclast, but again in my system and to my ears, a step even beyond the Iconoclast UPOCC. These cables are transparent, musical, and the imaging is magnificent. Ultimately, because of the deal I got on the Iconoclast UPOCC, I decided to use that cable between my pre and amplifier and use the ZenWave ICs from source to preamp.
The Iconoclast is an outstanding cable. The new version of the ZenWave D4 cables took things just a step further in my system and were worth the extra cost to me. I’ve since also upgraded power cables to ZenWave as well, from some Audioquest and Triode Wire Labs.
