Know before you buy
Unlike traditional tone controls that can color or degrade the signal, the three rotary switches on The Enhancer allow you to precisely adjust the de-emphasis curve. This lets you match the specific equalization characteristics of various historical record pressings and labels, ensuring the most accurate playback possible.
Yes, the unit is highly flexible. It typically comes configured with five MC inputs and one MM input, though the manufacturer can customize this to a 1xMC and 5xMM configuration upon request to better suit your specific cartridge collection.
By utilizing a purely active circuit design instead of step-up transformers, the Enhancer achieves superior signal-to-noise performance and avoids the potential coloration or impedance matching issues often associated with transformers. This results in a cleaner, more transparent sound profile.
Absolutely. Each unit is meticulously hand-constructed in Germany using point-to-point wiring, which is widely considered the gold standard for reliability and signal integrity. This traditional construction method ensures the unit is built to last for decades.
The minimalist, zero-feedback schematic preserves the natural dynamics and harmonic richness of your vinyl records. By avoiding global feedback loops, the amplifier maintains a more organic, lifelike presentation that is highly sought after by audiophiles.
Yes, the parametric control system is specifically designed to approximate nearly all phono equalization characteristics, including those from the pre-microgroove 78-rpm era. It is an excellent tool for collectors who listen to a wide variety of historical pressings.
