For the first time in more than 25 years of audio reviewing, I was hearing a component that caused me to enjoy my own reference system less when I reinstalled my regular preamplifier. That's one problem I don't face when I review entry-level bookshelf speakers!

Not long ago, the Signature Mk IIa was the finest preamplifier you could buy. In production since 2000, this enduring classic marked the introduction of the basic, fully balanced, zero-feedback, transformer-coupled Class A1 triode topology found in all contemporary VAC preamplifiers. Even from this early form, it preserves and reproduces the emotion and vitality of music and maximizes the performances of the associated source components and power amplifiers.

The Valve Amplification Company's Signature SE preamplifier is the most significant audio product I've ever hooked up to my reference system. It was flawless. Overall, based on my aural memory, it exceeded the performance of every other preamp I've heard in my house.
