Over the decades GVA that is GValveAudio has been involved in good quality audio (hi-end hi-fi). From very early years, build quality control, and achieving the very best quality of sound have been paramount.
Over the years GVA has built valve amplifiers, and indeed a number of solid-state ones, always trying to improve but never being entirely satisfied with them.
Finally after the last five years of research and development the GVA-30 is announced with each of the amplifiers hand built to order in the Southeast of England.
