Cyrus Audio Pre-XR Preamplifier

The Pre-XR has taken the performance of Cyrus preamplifiers to the next level. Comparing it to Cyrus Audio’s existing DAC XP Signature, we have increased the dynamic range to 110db, added the huge capabilities of the 2^nd generation QXR DAC and it now includes the same built-in phono stage from the i7/i9-XR amplifiers.

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 regulates quiet power.

Digital control circuits are assigned a separate mains power supply, completely isolated from the signal circuitry.

Output Options

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.
