Our Tools
Perfect the performance of turntables and phono cartridges, audio components, and complete audio systems.
When Jim Fuller visits for a system performance evaluation, he has the advantage of hearing your kit with beginner’s mind, starting by simply noting speaker and component placement, because these may contain visual cues that can reveal lost potential for quality sound. He will listen to a few test music tracks, evaluate source and amplification components and analyze speaker placement. Listening or measuring or both from the room’s “sweet spot,” he will determine if any incremental adjustments might be made to get better sound…including;
- Improved stereo separation and depth,
- Expanded musical soundstage,
- Extremely pinpoint instrumental and vocal imaging within that stage,
- Optimized tonal balance.
The goal is to allow all the music to flow that your system will allow by removing constraints to that flow.

Fuller Sound specializes in setting up and optimizing the highest end turntables and phono cartridges. While some high end audio dealers have specialists on site who may travel locally, Jim Fuller offers the ultimate customized service experience: he will bring his expertise from New England to your chosen location, across a region, a country, or an ocean. His mission is to tune your system or turntable to its peak performance, analyzing such specialized parameters as azimuth, alignment, overhang, anti-skate, vertical tracking force, vertical tracking angle, stylus rake angle, rotation speed, accurate phono stage loading and gain setting. Also, advanced levels of analysis include THD measurement, frequency response, tonearm resonances and enhanced FFT analysis. The difference is obvious. Jim has set up, tweaked and deep-serviced literally thousands of high-end turntables over the past three plus decades. He can calibrate yours to perfection, then advise you on how to maintain optimum performance.
"I had a well-used, well-loved Quad pre-amp and Quad at the time had no US representation -- and the unit died. Turned out a key circuit board was done for with no easy fix-- and no ready custom parts. That didn't stop Jim, who analyzed the problem, researched his options and found the parts to fix the problematic elements. In the process Jim was a model of persistence and dedication -- on a problem he could as easily written off as too much trouble. That was years ago and the pre-amp purrs along. I founded and ran SOTA Industries (turntables, speakers) for a dozen years and I had no better, more professional, or savvier dealer than Goodwin's. Jim and Goodwin's make a great duo."
Jim Fuller is a consummate professional with deep knowledge of every aspect of audio. Jim’s skill, meticulous technique, and exacting standards were invaluable in setting up the Basis Audio A.J. Conti Transcendence turntable in my listening room. Jim combined this skill and uncompromising ethos with a willingness to do whatever it took to extract the greatest performance from the system. I also found him to be a very astute listener with keen insights into how to optimize the listening experience.

A friend recommended Jim Fuller when I was looking for someone to replace the cartridge on my Rega Planar 3. Jim knew which cartridges worked well with that tonearm, gave me a range of choices, recommended the one he knew would work best. His recommendation was dead on right, his workmanship was impeccable, and I heard sounds from my LPs that I’d never heard before. Since then he has rebuilt my Quicksilver Audio preamp and monoblock amps. His assessment of what the equipment needs reflects his understanding of their design and their potential, his estimates are accurate, and every time I am amazed at how much better each component sounds. He knows the technology thoroughly and he’s completely down to earth and unpretentious despite the fact that he deals with really expensive high- end systems.
“On the other hand, in just 6 hours Jim disassembled my old Basis Debut Vacuum turntable, assembled a new Basis Inspiration turntable, mounted a Superarm 9, installed a Goldfinger Statement for listening test #1, dismounted the Goldfinger and installed a Lyra Atlas for listening test #2, then re-installed the Goldfinger for final listening tests. And all the while he was working he took the time to patiently walk me through the process and answer every question that came up. When he was done, I truly felt that my new 'table was set up as perfectly as was humanly possible. Although I'd mentally prepared for the setup taking until at least midnight, here it was 4:00 in the afternoon and we had nothing but time to kill until we went out to dinner. The bottom line is that Jim is one of the most knowledgeable, approachable, and down-to-earth people I have met in my journey through audiofoolia - an exceedingly rare combination of a terrific person who just happens to be skilled beyond belief.”
I originally met Jim circa 1990 when, on his advice, I traded my JBL speakers in on a pair of Snell Type K monitors and a Rega Planar 3 Turntable. The improvement in performance over my existing system was ethereal to say the least, and my journey to discover musical nirvana was officially put in motion. That original encounter eventually led to the discovery of a mutual interest in all things analog and has subsequently blossomed into a 30-year friendship. Across that arc, there has been many subtle….and not so subtle upgrades to my system, and I have consistently relied on Jim’s guidance along every step of the way. His unique combination of technical and aural acumen is unique in the industry, and there is no one else that I would even consider getting advice from, making repairs to, or tuning up my system. During a recent visit to my home and listening session Jim commented that “it was quite a system that I had curated”. I have never thought of it in those terms……but this explains Jim’s approach to high end audio better than any additional ink that I could spill down on paper. I’m extremely happy with overall synergy of my system and the wonderful music that it reproduces into my listening room. This would not have been possible without Jim’s guidance and advice along the way.
