The sound is great -- sweet, refined, full of dynamics - fabulous on grand piano.
Tony Faulkner, Greenroom Productions, UK owner of HV-3D and M-2B preamplifiers

The HV-3D is one of the finest pieces of gear with which I have ever had the pleasure to work. I use three of them to record the National Symphony Orchestra at the Kennedy Center, with spectacular results.
Charles Lawson, Senior Recording/Production Engineer, WETA Radio, Washington, DC

This is an outstanding mic preamp. I’ve never heard our mics sound this clean on piano. We’ve been using our [46 channels of] Millennia preamps on everything...
Jack Renner, President, Telarc Records International

Our HV-3D is primarily dedicated to making a great drum sound instantly available. It’s truly a beautiful thing and it sounds awesome... The HV-3D has added so much more to the feeling of creativity in our studio and I just want to say thanks for making such a great unit. It’s a solid piece of work, looks great and it sounds amazing - I’m in love!
John Haggins, DigiNote Studio, Miami Beach, FL

“For the HBO Live Broadcast of The Rolling Stones from Madison Square Garden 1/18/03, we used 82 channels of HV-3s on stage to drive about 800 feet of wire five stories down to the Silver Truck. I am absolutely amazed
at how good it sounded with that length of cable! Those HV-3s could drive the Atlantic phone cable to London!”
David Hewitt, Chief Engineer, Remote Recording Services

I like to get on tape (or on hard disc) what I hear in the room. When I was looking for a new mic pre, the main concerns were - no colouration, transparency and the lowest possible noise floor and reliability, because
we record 360 days a year. I simply could not find anything better than the HV-3D.
