Standard XLR Series
Requisite Mastering Cable is the single best upgrade you can make for your modern tube microphones and it can be done without alteration to the mic.
Custom Classic Series
The "Custom Classic" series of microphone cables was developed as a retrofit for the great vintage tube microphones by AKG, Neumann, Telefunken and others. Once implemented, the improvement in performance of these wonderful microphones is every bit, if not more, dramatic as the improvement experienced using Requisite Mastering Cable on standard XLR microphones.
Custom Modern Series
The "Custom Modern" series of microphone cables was developed as a retrofit for the current generation of tube microphones by AKG, B&K, Brauner, Neumann, Soundelux and virtually all others. Once implemented, the improvement is every bit as dramatic as that experienced using Requisite Mastering Cable on standard XLR microphones.
