Based on available user reviews and community discussions, the Purist Audio Design Diamond Revision CAT7 ethernet cable receives generally positive feedback, though opinions on ethernet cables for audio remain divided in the community.
## Sound Quality
Users consistently report noticeable sonic improvements after installing this cable. One reviewer stated it "disproved that theory in a most musical way" after initially believing ethernet cables wouldn't affect sound quality. Another user described hearing "shimmering detail, fine soundstage, and excellent, architectural and stentorian bass," noting it's "a very big sounding cable, in a good way." Additional testimonials highlight qualities like clarity, depth of soundstage, and responsiveness in the audio presentation.
## Build Quality
The cable receives strong praise for construction. It features hand-crafted manufacturing in the USA with premium materials including single crystal silver shielding, individual pair and overall cable shielding, and ultra-high quality GG45 TERA connectors. Users specifically commended "excellent" build quality, and the specifications indicate an estimated 100-hour break-in period.
## Value and Reputation
One reviewer considered it exceptional value for money, stating: "This is one of those cables that you can say without hesitation that it is a high-end product. Manufacturers have accustomed us to the fact that for 1,600 zlotys we can only dream about entering this exclusive club, but Purist Audio Design does not seem to care about the price barriers." The cable performed best overall in a comparative test despite not excelling in every individual category.
## Weaknesses and Skepticism
Not all feedback is uniformly positive. One audiophile forum user stated they "tried the Neptune Diamond Revision power cord and hated it," though they separately praised the Cat 7 ethernet cable, suggesting mixed experiences with the brand's product line. Additionally, some audiophiles question whether ethernet cable differences matter for audio at all, though this cable appears to have converted skeptics in practice.
