VAC CPA1 Mk II Triode Preamplifier
VAC CLA1 Mk II Triode Line Stage
VAC CPP1 Mk II Triode Phono Stage

The VAC CPA1 Mk II is quite simply one of the world's finest preamplifiers.  Audio signals are at their most fragile in the preamplifier.  Great care must be taken to preserve the original music without degradation, for even the best power amplifier in the world can not recreate magic lost in a preamplifier.

From the separate 22 pound regulated separate power supply to pure Class A triode audio path, no aspect of performance or design has been neglected in the CPA1.  The phono stage has switch selectable phono impedance, capacitance, and gain (up to 65 dB) for quick optimization with almost any cartridge.  The line stage offers three gain modes (up to 19 dB), including a buffered-passive mode using just a single Class A triode cable driver.  Dual mono stepped level controls ensure transparency and spacious soundstaging.  Connections include five line inputs, one tube buffered tape loop, dual main outputs (for biamping), and optional balanced outputs.


The CPA1 Mk II is one of an elite few preamplifiers capable of reproducing recorded music with a maximum of reality and emotion.  It stands at the heart of the world's finest music systems.

The CLA1 Mk II is similar to the CPA1 without the phono section.
The CPP1 Mk II consists solely of the high performance phono section for dedicated outboard use.
