Alón’s new toy: UberLight Flex

Mar 29, 2021

I turn 61 this month and my eyes seem to need more light than ever to do their job well.  I’ve always been a warm glow incandescent lighting kinda guy, so when I’m just needing to find a record’s lead-in groove in my dim listening room I can use the warmest color-temperature setting and lowest light intensity setting. But when I’m fiddling with a cartridge set-up or cleaning a stylus, or trying to read the small words on the back of a component, Kick it all up to maximum and wow, what a joy to be able to see everything again!   So,…

New Toy – Spiral Groove SG 2.2 by Larry Deniston

Jan 26, 2021

Well, doing as I do, several months ago while enjoying listening to my system, I was also thinking about the next upgrade. Where’s the weak link in the current system? What’s going to give me the biggest bang for the buck if I make a replacement? It’s always been part of the process for me. That, and instigators like David and Kevin, who are always happy to “help” with suggestions for the next piece of gear. I believe it was David that suggested the Spiral Groove when he learned that I was considering a replacement for my VPI Prime –…

Speaker Cable Questions Answered by Galen Galeis

Jan 22, 2021

1. Is it better to run long cables (RCA or XLR) or long speaker runs?  It is better to keep the signal at the load end, and not on the cable itself. A speaker cable has many amps of current, and the current squared times resistance losses go up with the square of the current. This is why speaker cables are such heavy aggregate AWG size, to make the cable look invisible to the current relative to the 2-16 ohm load. If our speaker cable was twice the resistance of the load, most of the signal would be lost across…

Iconoclast Introduction and Cable Comparison

Dec 30, 2020

Iconoclast Introduction and WireWorld Cable Comparison Albert Dall Hello SFAS members, As a lot of you have heard, since spring and Covid shutdown times, I’ve been changing my system around quite a bit. It has been turning out for the better. One of the first tests of change I implemented involved speaker cables and interconnects. I ran across the PS Audio Forum https://forum.psaudio.com/t/belden-iconoclast-interconnects-and-speaker-cabling/2038 where there was a long-running discussion of some new cables. This was the Iconoclast Cables discussion thread that dates back to March of 2015. What I enjoyed reading was how the cable designers Galen Gareis and Bob…

Smyth Research Realiser A16, Product Review, by jazzfan

Sep 23, 2020

The Worlds Most Advanced 3D Headphone Processor Pros Best 2-channel/multi-channel 3D virtualization available Personalized capture/reproduction of actual measured speakers and environments New feature upgrades available via firmware updates Cons Expect a steep operational learning curve The user interface is less than optimal The small display panel is challenging to read from a distance Optimum performance can only be achieved by taking personal measurements The unit must be returned to the UK for service/repair Preface Since I began this hobby in the mid-70s, I always preferred the three-dimensional holographic presentation of a good stereo sound system. Today well-recorded music on the…

MSB Technology Factory Visit, by Larry Deniston

Jul 26, 2020

After SFAS received a generous donation of HiFi equipment which included an older MSB DAC that needed repair, I was lucky enough to have the opportunity to visit the MSB Technology factory while dropping off the DAC.  Even though they were in the midst of moving into their new factory location in Watsonville, brothers and co-owners of MSB Technology, Daniel and Jonathan Gullman were very cordial and accommodating.     All of the MSB products are designed and manufactured in the US, so it was great to be able to see their headquarters.  The MSB chassis and modules are made…

New Toy, Spatial Audio M5 Sapphire, by Larry Deniston

Jul 25, 2020

Spatial M5 Sapphire Speakers In looking for the next improvement in my system, I started thinking about speaker upgrades and thinking about open baffle designs.  I'd heard the Linkwitz open baffle speakers at Kevin's, Don's and Linkwitz' homes and always was very impressed.  While impressive, the Linkwitz require a larger room than I have (according to the Linkwitz website) and was somewhat deterred by the multiple amps and active crossover required to drive them.  Then I remembered some other open baffles I'd heard at some audio shows, particularly the Pure Audio Projects and Spatial Audios.  As I conducted my research,…

Alon’s Big Idea – SFAS Focus Groups and Other SFAS Initiatives

Jul 22, 2020

SFAS Initiatives: Alón's Big Idea- SFAS FOCUS GROUPS Since its inception, one of the prime directives at SFAS has been to build a robust, interactive community of music and gear enthusiasts.  We must have done something right, since our gatherings have proven to be wonderful and warm experiences that brought many new friends together to share stories and wisdom related to our collective obsession. Enter Covid. Stop everything.  No gatherings, no visiting friends, no dealers you could walk in on unannounced, and alas, no audio shows.  In a matter of weeks, our world turned upside down.  The only good news…

New Toy – UpTone Audio’s EtherREGEN, by Albert Dall

Jun 28, 2020

Hello SFAS Board and club members! I hope you all are staying safe and sane during these crazy COVID times.  Happily, the club has adapted to be as active as ever with weekly Happy Hour Zoom meetings, and multiple manufacturers talking with us each month.  In our audiophile world we may be more involved in our music and system listening than we otherwise would be, which is the only positive I can think of due to enforced lockdown. Starting last Fall, I began a revamp of my system and room. I envisioned a less cluttered, simpler and cleaner layout of…
