Collection: AGD Production

I have always been driven by my passion to merge perfection and beauty in the art of audio reproduction. That was the motivation behind AGD Productions, Inc., a company of innovative talent that started a few years ago with the commitment to channel that incredibly strong drive into something tangible that all audiophiles can experience.

In the Hi-End Audio market, many giant designers have created wonderful products, with the aim to deliver the best possible experience in the reproduction of music. With the launch of the “Vivace” and “The Audion” Hi-End Monoblock amplifiers, AGD made its own mark in the technological progress of this field.

Now with the AGD “Andante” reference analog-digital preamplifier, this journey, launched with so much passion, begins to look like a mission that cannot be halted.

During the last couple of years I had the opportunity to present and demonstrate the result of this passion at THE SHOW 2019, AXPONA 2019, and TAMPA 2020 along with the superb Ocean Way Audio speakers by Allen Sides, and at HiFiDeluxe 2019 and RMAF 2019 with the wonderful craftsmanship example of the speakers from Sigma Acoustic Design by Aldo Zaninello. The experience of offering the visitors of those shows the novelty technology of the GaNTube sound has been one of the most rewarding of my professional life.

We at AGD will continue to offer innovative designs and new products with the same passion and love for audio for many years to come. Stay tuned and you will be amazed soon again.

What clients are saying


  • Like Santa Claus...

    Verdant Audio is, by far, the best dealer of audio equipment I have ever dealt with and I am on the West Coast while Verdant is on the East Coast. Scott, the owner, is like the Santa Claus in the movie "Miracle on 34th St.": He makes recommendations about what audio equipment best suits your tastes whether he carries those lines or not. He gives you an opportunity to try products he has in stock. And he works with you, after the sale to make sure your happy even if it means returning a purchase. Who else does all the things?

  • I've had the great pleasure..

    ... of dealing with Scott Bierfeldt at Verdant Audio on a number of recent transactions. I’ve been a serious high-end audio enthusiast for decades and Scott is hands down the best audio dealer with whom I’ve worked. Scott’s audio knowledge is truly impressive. His style is entirely consultive with no sales pressure at all. Working with Scott is like taking audio advice from a good friend that is guiding me to the best choices. In addition, Verdant Audio has an exceptional selection of very fine audio gear. Scott and Verdant are highly recommended.ontent
