It is beautifully designed, well-made, and sounds absolutely great. The controls are well thought out, user-friendly and offer a really nice spectrum of “color” options from super hi-fi clean to funky without being overly “tweaky”. I wish I had 4 of them !!!

Sounds as beautiful as any pre I’ve ever heard

The Eusonia preamp effortlessly provides vintage strength and modern clarity. The design allows for a new sound every-time it’s used. I reach for it on every project.

It’s become my go-to pre for bass guitar

In a rack full of the greatest pre’s of all time, the Eusonia Audio Pre-1 stands apart for its rich tone and character.

I’ve used this pre on a variety of sources and it is amazing on EVERYTHING. Not to mention the best bass DI I’ve played through.

ORIGIN STORY

while i’ve always enjoyed using audio gear to make records, i never intended or imaged that i’d be making it. until…

a few years ago, i had moved from nyc to the sticks and the pre-amp of my beloved home stereo system was in need of repair. not wanting to lug the unit into a shop in the city, i made several calls to local electronics repair shops in search of solution. it seemed like a fruitless task; everyone i spoke to either had no idea what they were talking about, didn’t deal with high-end audio, or thought a capacitor was a sex toy. that is, until i called brewster electronics…

there, i spoke to the owner, dave powers, who instantly sounded like a dude who knew exactly what he was talking about. not only did he and his engineer, albert langella, bring my pre-amp back to life, he – knowing my profession and music credits – asked if i would try out a new tube microphone pre-amp he was building based on a rare 1970’s transformer he came across in his shop.

slightly skeptical, but also curious, i said i would give it a test drive at my studio. expecting nothing, i split the signal from a quality vocal mic and compared the prototype to my favorite mic pre’s – which happen to be some of the best mic pre’s ever made. i just about shit my pants when i heard it; the rough and tumble prototype with hand-written parameter designations sounded as good or better as anything in my arsenal. warm yet defined, thick yet open, pristine or slightly harmonically enhanced, tonal and dimensional. stunned, i immediately called dave back and said, “WHAT THE FUCK IS THIS, I MUST BE INVOLVED!”

three years and several iterations later, we are ready to release the PRE-1 as Eusonia Audio’s first piece of professional, all-tube, analog recording devices. i couldn’t be more proud or excited. and my colleagues, who are some of the greatest producer/engineers to walk the planet, have been raving about it. i’d not put my company name on it unless it sounded transcendent and singular. welcome to the world, Eusonia Audio.

SOUND SAMPLES

A few notes on the sound samples:

  • They were recorded mostly at 24bit/96k in various studios in the New York area. No EQ or compression was used in the recordings.
  • When we compared our pre to other top-of-the-line pre’s, we have withheld the name of our competitors out of respect for their brands. Those samples are labeled COMPETITOR.
  • For the shootouts, we split the mic signal and went into our pre and our competitor’s pre. Everything was level matched on the input and output gain stages.
  • Samples can be streamed in your web browser, or downloaded, via Dropbox.
