Exciting huh?
Actually, it's surrounded by one of these:
Now, I know, you folks in the SACD camp are not to happy with me about now. But this is my moment, so hear me out!

The Jupiter 2000 CD Player is housed in the Rega custom built extruded aluminium case and includes the heat sink base assembly to give added mechanical stability to the mechanical parts. The Jupiter also has the new top loading lid assembly. It uses the same basic circuit topology as the original Jupiter and Io but with improvements in the DAC (Digital to Analogue Converter), power supply and clocking stages. The Jupiter CD player has additional sonic improvements, to provide a higher level of performance over that of the Planet.
The dual differential Digital to Analogue Converter is based around two custom built IC40 DAC chips with separate DAC's for the left and right channels. DC servo control has been used in the post DAC amplifier and filter stages thereby keeping the capacitors in the signal path to a minimum. The power supply is made up from 7 separate power supplies feeding the mechanism, PLL, DAC digital and analogue sections, micro controller, display, analogue amplifier and filter. All the stages for the clock PLL and in the signal path are double regulated. There are two physically separate raw supplies for the noisy stages (motor drivers etc.) and for the clean stages (DAC, Clock & DSP etc.). The Jupiter has a generously rated toroidal transformer with separate windings for the two raw power supplies. The signal for the Mechanism is processed by a data regeneration stage, where the Data, Bit Clock & Word Clock are realigned and then fed to the Rega IC40 DACs for conversion. The Jupiter CD player uses a high stability oscillator module for the main clock. The Master clock feeding the CD Mechanism and DSP is derived from a PLL clock stage for added stability. The Jupiter uses a high performance CDM145BL-5BD25 kit with an improved display and a better level of user functionality.
Digital to Analogue Converter (DAC)
IC40 D A C
The new Rega IC40 DAC is a high performance 24 bit Converter. It employs a novel 64 level sigma delta DAC design which provides optimised signal-to-noise performance and clock jitter. The Rega IC40 consists of a three stage linear phase FIR filter followed by a 16x over-sampled linear interpolator, that significantly reduces high frequency images when compared to the more usual sample and hold implementation. With the 64 level sigma delta DAC the magnitude of errors induced by clock jitter are significantly reduced and this is further enhanced by switched capacitor implementation of the low pass filter, which is also insensitive to clock jitter.
It will be here Wednesday! I am really looking forward to it too!
I got a great deal in it from http://www.signaturesound.com
