Cyrus Pre-XR

The Pre-XR has taken the performance of Cyrus preamplifiers to the next level. Comparing it to our existing DAC XP Signature^ we have increased the dynamic range to 110dB^ added the huge capabilities of the 2nd generation QXR DAC and it now includes the same built-in phono stage from the i9-XR amplifier.

Analogue Preamplifier
The Pre-XR analogue preamp features relay input selection and a new high performance gain stage. This short-path design makes the analogue preamplifier extremely transparent. With four analogue inputs and phono MM^ the Pre-XR will cover just about any system requirement for analogue connectivity.

High Capacity Power Supply
The power supply design of the Pre-XR has received special attention. An over-specified 74VA power transformer delivers power to a high capacity power supply reserve. Within the circuit design^ a generous total of 15 independent power supply regulators regulate^ then sub-regulate quiet power. Digital control circuits are assigned a separate mains power supply^ completely isolated from the signal circuitry.

Balanced and Unbalanced Outputs
The Pre-XR features a choice of balanced audio drive via XLR connectors for best performance in systems where it is partnered by high-end power amplifiers with balanced inputs. An unbalanced output is also provided.

PSU-XR Port
The Pre-XR includes a port for the new PSU-XR power supply. Thirty years ago Cyrus broke new ground with the introduction of the PSX^ the first ever regulated power supply upgrade that automatically adapted to match perfectly the power requirements of any connected product. The PSU-XR raises the bar by sourcing no less than five independent regulated supplies in a single box. For the Pre-XR the PSU-XR steps in to take over power supply for the analogue stages of the preamplifier.
