From the moment I contacted Kenny, and based on other reviews, I knew I was in for a real treat, and he did not disappoint. Easy to contact and responsive to all emails and questions, and I had more than a few. The gear! I purchased a beautiful ST120 SS Amp and PAT4 preamp. From start to finish I think it took a few weeks to arrive. Timely emails along the way kept me informed. The gear arrived perfectly packed and for 50+ year old gear, look brand new. He really works wonders with this Vintage Dynaco gear. I’ve been happily listening to my new gear for 3-4 days, all day now and I am so pleased I went with Kenny. The sound quality, detail, separation and warmth is just absolutely wonderful. I’m using a pair of Klipsch Forte 1s and to my ears, it’s sublime. I wouldn’t not hesitate to recommend Kenny for one second. It’s true, you get what you pay for! Craig D. (ST-120 Enhanced + PAT4)

"Both amps are sounding better with every listen. You might want to sell stock in Funtastic Vintronics!" Without Ken and the craftsmanship his works exemplify and the willingness to sell these wonderful Dynacos at reasonable prices, tubes would take a huge hit in popularity! Most of his units are state of the art examples of what modern electronics can do whilst keeping the great tube sounds we love as well as the classic Dynaco looks. I am lucky to have two of his Dynacos in my home and a third on the way! Ken is very communicative and freely gives good advice when asked for it. He has supplied me with documents and schematics so I can understand every part of the circuits installed in the units. As far as I am concerned one of his masterpieces should be added to the Oklahoma State flag! Thank you Ken!- Noel (ST-35 and ST-70 with Evolution 4T Driver, PAS-M Preamp)

The amp is ridiculous. Just ridiculous..... - Brad O. (Stereo 35 Tube Amplifier)

"I have to stop myself from taking the cover off to show my real audio friends. I'm gonna wear the screw holes out on it." - Eddy (PAS-M Preamp)

Several weeks ago I purchased two Dynaco ST-70 from Kenny. He discussed potential options WRT upgrades and then went about building both units quickly and with extreme precision - as I waited for the day when they would arrive. In the interim, Kenny provided diagrams that explained how to configure the amps as mono blocks. The amps arrived in less than three weeks. They were well packed and beautiful to see upon unboxing. After installing the tubes, getting the speaker wires hooked up, and plugged in the power - it was time to see them light up. And light up they did. Within a couple of moments, out came sweet beautifully separated stereo music owing to the mono block configuration. The notes, chords, vocals, strings and any other instrument playing through my Klipsch's were crisp and clear in ways I had never heard before. I quickly learned the meaning of listening to music though tube amps. I suddenly knew why I had wanted a tube amp for years. Wonderful, staggering, mind blowing, heavenly, precise, and real. In the end, there was nothing more to ask for...These amps sound great!!!! Amazing… - Lee P. (2 x Dynaco ST-70 Tube Amplifiers)

"Dammmm ! That is the smoothest, most controlled bass I have ever heard from ANY amplifier !!! You did a fantastic job on this - it sounds staggering ! - Alexander H. - (Stereo 120 "Enhanced")

It is dead quiet and the sound is very musical with my older Paradigm speakers. - William M. - (Stereo 70 Tube Amplifier and PAS-M Preamp)

Absolutely love my unit! This has got to be the greatest customer experience I've had in years. The communication was timely and accurate. I never felt pressured or thought I was being "sold something". The Dynakit based PreAmp PAS-3(M) sounds amazing. It's the perfect combination of Vintage and New technologies. Thank you, Funtastic Vintronics. You're the best! - Eddie B. (PAS-M Preamp)

I finally got the Dynakit PAS-M and Stereo 120 NG from Kenny. When I first heard it all connected, I said WTF is this! The way it sounded with all my speakers astounded me regardless of cost. Out came this lush, warm, detailed sound I never heard before with anything I've had in this room. Even the phono stage blew me away. I decided to send back the Schiit Freya Plus and Loki and pay the 5% restock fee. Here's a guy by himself that hardly anybody knows about putting passion into a chassis at an extremely affordable price and knocking it out of the park! For me what determines how good a sound system is, is how it connects me emotionally to the music. I was emotional in ways I wasn't before. Kenny does world class work and I'm having a funtastic listening experience. :) - rankaudio @ audiogon - (Stereo 120 "enhanced" + PAS-M Preamplifier.)

"Blind sound test, my wife the listener. First...your Dynaco solidly outperformed the Yamaha, my wife could hear a cleaner sound at higher volume. This was with just the 901s. Your amp is beautiful man, and it rocks. System: all vintage, Sansui preamp, Technics turntable, JBL Centuries. Kenny's Dynaco clearly outshone the Yamaha amp it replaced. Then I really put it through its paces. Classic rock, jazz, etc,...what amazed me was how I could turn up the vinyl volume to 7--way too loud for a living room--and the amp was still dead quiet, while sound reproduction was superb with no distortion. String bass, horn, electric guitar, voice--all sound fantastic, at any volume. I take a modest pride in my oldschool system, but the Dynaco is my secret weapon. - Phil (Stereo 120 "enhanced")

"I'm running a pair of Magnepan .7’s, Heresy II’s and Caintuck Lii Fast 8’s with a REL t5i sub with each system. I’ve compared lots of top rated components. I just ordered another Dynakit Stereo 120 solid state from Kenny at Funtastic Vintronics again and I’m selling off everything else to have two systems. This includes all my tube gear and I can’t believe I’m going to solid state but this is the exception. This amp just demolishes everything I’ve compared it with. It has a spatial separation exactly like tubes but with all the fast bass attack you get from solid state and it gives my Heresy’s an incredibly pleasant sound. It’s sounds absolutely magnificent and you can run it as an integrated amp if you get it with a volume control. It drives my Maggie’s perfectly. Competes and outperforms anything I’ve compared regardless of price. It’s all updated with new parts and just $600!" - Daniel M. - (Stereo 120, PAS-M Tube Preamp)

"It is amazing, zero distortion , great power and it really makes my Polk Audio RTA 12 B’s zing. Great seller. The rebuild he did to the amp I bought from him was amazing. WOW, compliments the system very well. Thanks again." - Abe (Stereo 120)

"Kenny, Kenny, Kenny!!! Holy S**t, This thing just gets better" - Gary C. (ST-70)

"I added a tip for all the fast work you’ve done. Thank you for making this such a great experience!. "There aren’t enough positives I can add here! The tube amp was a work of art!!" - Ryan G. (Dynakit ST-35)

"When I see such a detailed craftsman's labour, that's when I see pasión and love for what you do. Absolutely incredible in every aspect and detail." - Alvaro (ST-70)

"a true artist, his quality is untouched, I have been in this racket for years, by far the best work I've ever seen,better than Dynaco themselves and that's saying a lot, pay a little more it's well worth it" - Scotty S. (Dynaco 70)

"Your workmanship suggests you also take a lot of pride in the products you build & sell" - Kevin D. (owner, Dynakit Inc.)

"A+ seller. Excellent restored amp, accurately described. Great packing, communication, too" - Joe S. (Dynaco 70)

"One of the best online transactions I’ve ever had. Description was spot on and the seller was very helpful. The item was packed so well it took me 10 minutes to unpack it. Would not hesitate to business with him again" - Eric L. (Dynaco 70 & PAS-M)

"With the new preamp you made, this shimmer comes through more clearly more defined more vibrantly than any other preamp I’ve ever heard" - Daniel M. (PAS-M)

"Stunning build quality. Very happy with my new amp. Thanks again!" - Steve M. (Dynakit ST-35)

"Kenny, now I can’t damn well sleep because I can’t stop listening to this thing! You were right. This is definitely a giant killer!" - Dan (Stereo 120 "enhanced")
