On the lake, water birds glide gracefully with harmonious precision, the subtleties of each feather reflected on the calm surface of the glassy pond. In like fashion, the DGA-1 reflects the spell- binding quality of the sonic moment. If that moment has thunder claps or gentle waves meeting the beach, it is given to you in a way you can feel to the depth of your being. You will be blessed by its presence, if you take the opportunity to listen to this, the most basic member of the Whammerdyne Truth family.
Damn Good Amp DGA-1 new for 2019
Whammerdyne “Damn Good Amp” (DGA-1) Newly revised for 2019
What you get with our entry model. Direct input no capacitors from the volume control to input of 6922 gain/drive tube. Pure DC coupling with no capacitors, resistors or transformers between the input 6922 tube and the 2A3 output tubes. The chassis is a single unit all heavy gauge machined aluminum with an internal layout that minimizes interaction with the power transformer and output transformers (specially shielded). (7) Fully regulated DC filaments and tube plate (B+) power supplies. Its a dual mono design so isolation between circuits is minimized. Pure class A operation, Zero Feedback. Tubes as installed will be NEW issue and fully tested/matched. We have integrated an updated version of our E-Z bias topology so now bias is even simpler using only two trim controls takes seconds and continually reads out on dual LED current meters. We use proven design technology derived from our upper models in many key circuits. Very low measured wide-band hum and noise, over 115 dB down (you will not hear any noise/hiss in your efficient speakers) The sound is fast, transparent, detailed, bass has impact, unlike all other brands of SE amplifiers on the market.
Options: NOS (New Old Stock) computer matched tubes at additional cost. We also offer an optional level 1 output transformer upgrade giving you added bandwidth this lowers phase shift in the audio band and the special core material lowers transformer distortion. (I have been asked by many if you can use a pre-amplifier with our models of amplifiers and the answer is YES, just connect your favorite pre-amp to the inputs and turn our volume control up full, this effectively takes our control out of the circuit. But our amp is an integrated so you can also use it without a pre-amp no problem)

“Best of all, it’s not out of reach of any music lover. With a wider palette of high efficiency speakers available these days, you might want to revisit just what a few of the right watts per channel can do. This is the best of the best” Jeff Dorgay- Tone
What customers say:
“I have put in around four days of listening to your amp in my stereo system and I have to say this thing is the biggest upgrade I have ever made. I try to keep my expectations modest with most changes to my system but this was too good.
Not only does it control the Devore woofers at the low end with much better grip but the highs a deliciously sweet. For the first time I have a noticeable increase in depth to the soundstage as well. When listening to free jazz I can follow individual lines without any blurring or homogenization of the various instruments. It’s really remarkable. And this is all with a very sub optimal source until I receive my turntable from overseas. Drums have never sounded more tonally correct with all the different overtones and shadings they can convey, and vibes just hang in midair forever. And this amp is fast with attacks that barrel forward with momentum. The entire frequency range is just superb. My dad even showed up and said “it seems as if Bill Evans is in the room with us.” My biggest surprise is that the amp never even gets past half way wattage meter and these half to fill out a substantially sized room. The head room on this amplifier is stunning and all with just four watts. Once you hear it you can’t un-hear it is an understatement. Congratulations Pat on a wonderful product and it’s going to bring me years of pleasure. Now to pick my jaw up off the floor and listen to some more music!!”
My warmest regards, Tim L
“After a year and a half with the DGA1 (serial #: 001!), I love it even more than when I first received it. I don’t know if there is any truth to audiophile electronics needing “burn in” time, and frankly, thought it was hogwash, but the amp is really warm, rich and powerful, even better now after a year and a half.
Paired with the efficient Klipsch La Scalas, it is not surprising the mids and highs are really strong (both strengths of good SET amps and the Klipsch La Scalas), but what is surprising is the full bodied, punchy, and rich bass. Is it possible your amp is getting better and better over time? Can I really trust my own ears? I say an emphatic “Yes!”
I have a quality vintage velodyne sub as well on the system, and while it’s a great addition, it’s not necessary for rich, full bass, which is a total shocker.
Thanks for the great work, I’m proud to be proud customer 001!”
