Serrano Vintage 87: Black Friday Preorder Sale

This is possible, of course, but in my humble opinion not necessary. For the past 3 years I have been using Guosheng Zhuang's (3U Audio) K87 capsule. I cannot speak for every capsule Guosheng produces but his K87 is truly incredible in how close it is to a genuine Neumann K87 capsule. I have tried many, many capsules including several custom-designed ones, featuring different backplates, variations in gold thickness, and even some crafted with platinum. After about a year of making my first version of the Serrano 87, in 2021 I was able to source a vintage U87 in immaculate condition and further tweaked the Serrano Vintage 87 to match it. It was at this point that I spent a lot of time with Guosheng's K87 and I honestly cannot say that his K87 is any lesser in quality than a genuine Neumann K87. My thinking is that they are within 95-99% of the same tonality and 100% of the same sound quality. Some may disagree with this perspective, but I would wonder if their viewpoint is shaped more by theoretical insights from other experts rather than by extensive hands-on experience with both capsules. There's no doubt that the Neumann K87 capsule is of exceptional quality, but I’ve found that it’s not the only option at that level.
