AGD ALTO Reference Analog Line and Phono Preamplifier

The AGD “ALTO” is a complete audiophile Line and Phono Reference Preamplifier that delivers a unique set of features and components in a very compact beautifully crafted single billet aluminum cabinet.

 

 

With his built-in fully balanced phono stage (MM & MC), a volume control with the most thermally stable and high precision resistor ladder circuit, the “ALTO” is by design the perfect companion preamplifier for our “TEMPO” and “Audion MkII” power GaN Amplifiers.

 

 

The ALTO’s Phono stage, is a fully balanced topology circuitry, with superior sonic performances that will satisfy the also most demanding Audiophile.

 

 

While The “ALTO” is by design the perfect companion preamplifier for our “TEMPO” and “Audion” Stereo GaN Amplifier, it will also deliver the most sublime and purest sound with any audio system of any standard.
 

 

The AGD Audio Design team is confident the “ALTO” will meet your expectations and as a team we will always stand in support of your needs and future requirements.

Engineered with audiophile-grade components — premium drivers, hand-matched crossovers, and a hardwood enclosure tuned for natural decay. Every cabinet is internally braced and damped to suppress resonance below the threshold of audibility.

• Custom 6.5" mid-bass driver with paper-pulp cone for transient accuracy.
• Soft-dome silk tweeter with neodymium motor for airy, fatigue-free highs.
• Point-to-point hand-wired crossover using silver-foil capacitors.
• Bi-wirable terminals plated in pure copper.

Place each speaker on its dedicated stand, toed-in toward the listening position. The hardwood enclosure resonates in concert with the drivers — a deliberate, musical interaction rather than a flaw to be eliminated.

Connect to a quality amplifier using bi-wired speaker cable for the most transparent presentation. Allow 50–100 hours of break-in for the drivers and crossover capacitors to settle into their final voicing.
