Rega’s now legendary head electronics engineer Terry Bateman spent 10 years researching the concept of a CD player using valves in the output amplifier. Valves have been widely used in musical instrument and recording amplification from the 1950s to the present day, therefore it made great sense to develop a valve based CD player to match that of the signal chain found in such applications. Valve version of our reference Isis CDP The valve Isis shares the same digital and USB sections as found in the solid-state version, however, the analogue stage is valve based with passive filtering. This stage uses two military specification triple mica 5814A (ECC82/12AU7) triodes being driven by the revolutionary Wolfson WM8741 ultra high performance digital to analogue converter.

Product Details USB Input Allowing direct connection to a laptop or PC via a USB A-B lead to stream internet radio, MP3 or WMA files directly from your computer via the high quality Isis internal DAC. The USB input uses an isolated double-clocked USB interface, which permits the digital to analogue stage to be used with a computer USB interface and its own regulated power supply. The USB benefits once again from galvanic isolation from the main circuitry of the Isis player which eliminates the flow of earth currents between the CD and host computer, and eliminate computer power supply noise. Disc analysis The valve Isis will analyse each disc on an individual basis. During the initialising period (rather like the engine management system on a modern car which optimises the engine settings to temperature, fuel quality etc.), the Isis will adjust itself to each disc in order to give optimal trouble free reading. For this reason the Isis will often play discs with marks or scratches that other players cannot read.We hope that you enjoy this product as much as we have enjoyed.creating it.
