Vivid’s new Giya G4
I also met famed Dutch engineer Bruno Putzeys in the On A Higher Note room, where the “substantially upgraded” production versions of his Mola Mola amplifiers ($15,000/pair) were being used to drive the Vivid G4s using Kubala-Sosna cable. (Philip O’Hanlon made Bruno wear his jacket for my photo of Bruno and Dic.) Jon Iverson has already reported on Bruno’s prototype DACsee here and herebut I was also interested in the new phono preamp board Bruno has designed for the $10,000 Mola Mola preamplifier. This is based on a discrete op-amp circuit, but with the discrete transistors guaranteed made from adjacent dies on the original wafer to ensure the best matching of electrical characteristics. An app for an iDevice will allow the equalization and loading for MM and MC to be switched on the fly, using relays to choose the appropriate resistors and capacitors. And as you can see from the photo below, Bruno shed his jacket in order to explain the circuits more efficiently to me.
