@bigkidz Well, I first gave advice on where to help market on-line, contacting the mags as well as influential reviewers. I don’t have time to do your job or hiring someone to do it. I don’t know if your equipment line is bad, good or mediocre. But when you mention one of my best friends equipment being modified or repaired by you, unless it was a mundane switch or toggle, I don’t believe you. Or a significant Lampizator product unless it was some non-DAC unit or a lower cost unit from 10 years ago when Lampizator wasn’t established with a rep in the U.S. yet. Good luck selling your equipment line.
The not so secret to GroverHuffman’s equipment is severe type of power regulation beyond the several Audio Research crude basic models. More like my Westminster Labs 10 levels of power regulation in my Quest 2 preamp. His Dynaco Stereo 70 beats every other unit I’ve heard in 50 years because he said he uses the center transformer tap for voltage regulation (plus a huge storage cap under in the bottom chassis). It is no longer a ultra linear amplifier. The bass is phenomenal compared to the stock flabby bass. It is otherwise upgraded with excellent speaker terminals, RCA connectors and IEC plug for use with high end power cables. Several friends use it as well as for my second audio system. Sounds as loud as a Mac 30 but with superior control and extended linear frequency response. His patented cables are also excellent for the price. I have a mixture of his cables, especially for the analog components and digital cable versus the majority of my system with SOTA cabling from Westminister Labs Ultra line and some Masterbuilt Ref2.
I am also an amateur recording/mastering engineer with two recording archivist titles to my name for classical composers and 150+ recordings of orchestral, chamber and choral music at major Los Angeles venues. I do it because I get to keep the masters and make performers happy. I’m not equipped with electronics knowledge as manufacturers are but I have a good ear and some of my friends are well known analog remastering engineers who are professionals and whose productions are sold world wide.
