Ortofon SPU #1S and the Enigmatic Spherical Stylus


Garrard 301 + Ortofon RMG309 + SPU Classic GME

It seems like yesterday when my SETUP friends Joel, Nonong and William gifted me with an Ortofon SPU Classic GME cartridge for helping them get rid of the upgrade syndrome afflicting their high-end audio sensibilities back in the mid 90s. Within the same time frame, I was frequently talking shop with Sound Practices editor and publisher, Joe Roberts, regarding my Homebrewer article. At some point, the conversation segued to the virtues of the spherical or conical stylus based on the research done by Reto Luigi Andreoli (published in German by Christian Rintelen in Hi-Fi Scene Schweiz). Looking back, and at the risk of sounding ungrateful to my friends, would the humbler Classic GM have been a more appropriate gift? 😇


In the process of hunting for an original SPU with conical stylus, I instead landed three Denon classics - a ca. late 80s DL103, DL103S and DL103C1- for the price of a then brand new DL103R. Compared to a regular DL103, the DL103S is sweet and most extended in the high frequencies but least dynamic, the DL103R most detailed. The DL103C1 emerged as my favorite for combining all the virtues of the aforementioned models. These are very competent MC cartridges, which, along with the SPU GME, have been invaluable tools in voicing my audio system through the years. However, none of them could match the vivid midrange presence of the SPU.

Meanwhile, my spherical SPU hunting got sidetracked by Monaural playback and Retro Cool Tonearms and Cartridges.

Ortofon SPU Classic GME

In the intervening years, I had been fortunate to listen to higher-end Ortofon SPU models in familiar systems. Inasmuch as the SPU Royal, 85th Anniversary, Meister and Synergy offered better detail retrieval and extension in the frequency extremes to satisfy contemporary audiophile standards, I was never convinced that they were presenting a tonally more accurate sound overall.

Ortofon SPU#1S

After over 20 years, the idea of owning a spherical stylus-equipped SPU still haunted me. Fortunately, Ortofon introduced two entry level SPUs in 2016. I bit the bullet and ordered the cheaper SPU#1S with a bonded spherical stylus last year and couldn't be happier. Even if the #1S has slightly less top end extension than the Classic GME, the midrange is even more organic and soulful because the harmonic overtones are more akin to what I hear in a live music-making environment.


It's been known for decades that a conical/spherical stylus is kinder/gentler to the grooves. Thus records in less than perfect condition become more listenable traced by this type of stylus. Granted its technical inadequacies can be measured, which in turn has pre-conditioned audiophile beliefs for several generations, what matters most to me is still the enjoyment of music, and a measuring tool for that has yet to be invented.


While perusing various audio forums these past couple of years, I noticed that compared to 20 years ago there are a lot more vinyl aficionados who recognize and appreciate the musical merits of the humble round profile stylus. In hindsight, if the Retro Cool Tonearms and Cartridges article I wrote before my hair turned gray contributed to this trend, my efforts have not been in vain.

Velvet Touch, Calrad SV12 + SV16


I may have shot myself in the foot when I spilled the beans in the original Retro Cool Tonearms article many moons ago, before collecting all the desirable models of viscous damped tonearms. 


But it's all good - more good karma to come, hopefully. 😇


I no longer aspire to be as lucky as my buddy Ding with his Gray 108 and Gates CB77. 😞 But I recently found a transcription length Gray clone locally, a Calrad SV16 complete with original box and instructions.

Here we have the instruction manual for the Calrad SV12 which is also applicable to the Velvet Touch.

Pivot > spindle = 8 3/8"

Musicmaster Model 12 installed as per the above 8 3/8" pivot to spindle distance. Sounds okay. But read further...


This is my Realistic Mk VII idler turntable with a factory mounted Realistic A-3 viscous damped tonearm, which is identical to the Calrad SV12 and Velvet Touch.


 Pivot to spindle distance = 220 mm or 8.66142" or between 8 5/8" and 8 11/16".  

This is my preferred setting after listening to the following cartridges: Denon DL102, GE RPX and VRII + low cu stereo cartridges like the PickeringV15/Stanton 500, Shure M7D & SC35C.

I've also gotten good feedback from ears I trust regarding brand new Gray 108 clones from Karmadon. Serge has come up with variations on the viscous damped tonearm theme. This route is well worth pursuing since prices on eBay for the original 108 and clones have become ridiculous.

Happy Listening!

Kutztown Radio Meet May 11 & 12 2018

All pictures were taken with a Fuji X-E1 camera + Voigtlander Ultron 28mm f1.9 lens

 Radio shows around the country have continually diminished in scale. This Kutztown event, however, has become the biggest radio show in the east coast and is still growing!

There are still cheap tubes to be had if you're willing to get down on your knees and your hands dirty. But everything else is close to retail or eBay going rate.

I still remember cleaning and fixing these for Angela Instruments and I built my first pair of PP2A3 amps on these chassis

I listened to this combo in the 90s. I should've kept them. 😞

Holy Grail!

I go to this event mainly to hang out with old buddies like Chong and Larry R. Also made new friends with Francis S. who's been a frequent visitor to this blog and a dyed in the wool Western Electric/Altec enthusiast who has been carefully studying Altec 3000 tweeter repair.


Since the price was right, I adopted a single JBL D123. 


Will it be as good or better than an Altec? Stay tuned...

M42 camera bodies and lenses


A quartet of M42 SLRs
Between 2016-2017 I acquainted myself with these mechanical M42 SLR cameras and lenses. These four camera bodies left a lasting impression on me for personal, historical and sheer shooting pleasure along with the lenses I used them with. Aside from shooting film, I also adapted the lenses to my trusty Fuji X-E1.


Yashica Penta J + Yashinon 5cm  f2
I have a special affinity for the Yashica Penta J since my dad taught me how to take pictures using this camera. This was the first M42 mount body produced by Yashica. It doesn't have a light meter and the shutter speeds are limited from 1/2-1/500 + B but the viewfinder is fairly bright (at par with the Pentax Spotmatic) assisted by a split image focusing screen. The standard Yashinon 5cm f2 lens is rather special and has caught the attention of aficionados which has driven its value up recently.


Pentax Spotmatic SP + Super Takumar 50mm f1.4
This is the camera most closely associated with the M42 mount. It gets more credit for popularizing the M42 screw mount than the much earlier Zeiss-developed Contax S later known as the Pentacon SLR, shown below. It is similar in size to the Yashica above with a similar spec'ed viewfinder but equipped with more comprehensive shutter speeds from 1s-1/1000 + B. The built-in light meter is broken on this flea market find. I bought this camera primarily because of the sought after Super Takumar 50mm f1.4


Pentacon ZI + Isco-Gottingen Westagon 50mm f2
Pentacon F + CZJ Tessar 50mm f3.5
These two immediate descendants of the Contax S were manufactured in the former East Germany by Pentacon in the 1950s. They have a rather interesting shutter speed selector arrangement. There's a switch in the back which selects between slow (B-1/20) and fast (1/50-1/1000) shutter speeds. The shutter speed indicator wheel located behind a plastic window spins when the shutter is released. A very neat feature! Handling this camera is reminiscent of Leica screw mount bodies including the knob wind film advance. However, the compact and light body is ultimately let down by a rudimentary ground glass focusing viewfinder (tip: best used on a sunny day) and there's no instant mirror return. It was a time capsule shooting experience with these two cameras.

More info on Contax/Pentacon 35mm SLRs.

Fujica ST801 + Zeiss Jena Tessar 50mm f2.8
A very sophisticated mechanical M42 camera, the Fujica ST801 was very much ahead of its time. It sports a compact body, bright viewfinder fitted with a split image prism, 1s-1/2000 (!) shutter speeds + B with a built-in light meter which uses a 6V battery that is still readily available. This is my pick of the lot!

Lesser Fujica siblings
The Fujica ST701 has a top speed of 1/1000 and the light meter requires the obsolete Mercury cell. While the entry level ST605's light meter works with modern batteries, the top shutter speed is only 1/750. Nevertheless, these two cameras share the same compact body and bright viewfinder with its top of the line brother - ST801.
