I’m using the excellent QED Supremus speaker cable. The Jern 14 speakers are pinpoint perfect and are designed with the REL support in mind when I reviewed them, I said at the time “I cannot commend these speakers enough, for the money they are out of this world.” Fitting for me then that they should present the output from such a premium system, don’t take my word for it, just read the reviews on the Jern site, they all say the same. My review is based on the leads and interconnects from Rega and I’m using Jern 14 speakers supported by a REL 5i sub woofer on a Jern cast iron base. The Osiris amplifier, incidentally, probably wouldn’t stand stacking given the size of the gills at the side if it was being heavily driven. Because the CD is top loading style you’ll need a bit of head room. The Isis comes in with a custom solid anodised aluminium case weighing in at 19 kg and has the following dimensions: W 434mm x D 350mm x H 112mm. The quality is all laid out by the sheer weight of the box and the device itself. The Rega Isis (and Osiris integrated amplifier) come with their own big, punchy power leads and the Isis also comes with Rega interconnects that I am using into the Osiris. The analogue section of the Rega Isis employs two Burr Brown PCM1794 digital to analogue converters, running in a parallel dual mono mode, the digital section has 10 separate power supply regulators in the circuit so every stage is being absolutely optimised for pure performance to generate a “wide dynamic range, low distortion, and linear signal”.

Intuitively this sounds good to me, less messing about at the critical stages. This is meant to make for a purer sound when the current output is amplified to produce a pure analogue output. Rega has gone for no amplification in the internal DAC. There is loads going on with this top loading CD that makes for a pure quality CD sound.
