The regular visitors of my site know about my recent frustrations with my new Ortofon SPU cartridge for my “mono tonearm”: Is it all that Ortofon SPU can do? Today I made some alternations that more or less cured the audio problem and I decided ...

I juts got home, put a record to play and suddenly discovered that my SPU has it’s cantilever bent 90 degree and then even twisted vertically. It was perfectly fine last night!!! I have no idea what kind forced what appl...

I run both of my Reference and Daily tonearms into my “End of Life Phonostage”. As I told I do not know any way to commutate signals at phono level signal and I just re-plug the phono cables at the phonostage’s input. I have no problem with that ...

Well, maybe a little cussing first to set the tone. The older SPU's are now well sought after, many will end up in collections at now over inflated prices probably in the Far-East where they are worshipped. I've heard a few older SPU's and even those...

Hi Romy,On the Ortofon website those models of the SPU which don't come with inbuilt transformers, have a recommended load of >100 ohm. Using the cartridge into too low an impedance load definitely does lift the lower frequencies. Too high and the...

What you have there Romy is essentially the cartridge Ortofon introduced in 1948, the first production moving coil cartridge.
The motor is the same, just the "suspension" material changed from india rubber to a modern elastomer AFAIK. Also the G-sty...

Methinks that Mr C is correct in that the SPU cannot be deconstructed as I asked the same question elsewhere and got shouted down. :-( But hey, maybe they were minor league rookies and some major playa has the answer.... By the way ...

[quote user="Brian Clark"] My stereo corrector (834P with air-vane caps) has a shorting switch across the two channels at the input. I suggest you incorporate the same.With it out of circuit I did indeed get that hum you refer to with the SPU Mono. S...

After much talking with people I am still at lost what cartridge to get in order does not worry about cartridges anymore. It looks like I “fixed” the Shelter but now I need to take it off and to remove dust from within the cartridge – the ceremony I ...

SPU alright! White/Blue and Red/Green should carry identical signal so either pair will do.
The advantage of the SPU Mono is, like with the DL-102, you need have no worries about damaging stereo pressings.

I don't think it is possible to deconstruct as you desire. Perhaps you need to talk to Per Winfeld at Ortofon (I can give you the email address).
The SPU Mono has 4 coils rotated 45 deg and connected for vertical modulation cancellation. The CG 25...

Well I'll 'fess up to the possible reason that this thread has had so many hits, I linked it to a thread on another site that has a few 103 owners (and remember for every owner there are many reading/waiting to become disciples due to the "...

[quote user="Romy the Cat"]How much is what your appreciate in the SPU sound derives from the SPU’s high output.[/quote]
I think you must be referring to the T version with built-in step-up Romy. Current production SPUs have a quoted sensitivity ...

i agree that there are more audiophile cartridges around than the dl103. but except maybe for the ortofon classic, they all have non-spherical stylii. i am sure that a lot of the "air", "space", "bloom" etc. of today's cartridges is actually distorti...

The whole presentation of sound is very different with your and my file. Your file is very lush sounding. It is very pleasant but a bit too euphoric for THIS music. My file is much more dynamic (if comes from my transformer) and in the way this dynam...

Michael,
I never head Single Power gears, or ever herd this company. I kind of have very specific type of sound that am wiling to get out the headphones. It is hard to describe but it should be very-very soft and moist but still with upper bass horn...

That was very interesting romy. The SPU sound for me was always "woody", which isn't far from brown I guess, and ¨noble¨strikes me as well in the description (it really hits its stride on chamber orchestra or vocal recital for me). Shelter colo...
|
|
Maybe, maybe not although I'd expect it to be unlikely with a Koetsu, Shelter 901 or an SPU at the front! Not unless they are very different cartridges to the samples I've listened to....

I never hear them and never will as I have no quest for any better SPU but they might do something worth attention. No one knows until you try. They certainly have nothing at their website that set expectation high but it does not mean anything. I ge...

If it is the CG it should say Dia 25 somewhere - unless it is for 78s when it would say Dia 65.
"Dia" for Diamond, the number for the diameter in microns.
I guess if it doesn't say this it will be the SPU Mono.
Actually, if you remove it from th...

I even never thought about “damaging of stereo records” as there are other objectives to peruse mono cartridge.
Anyhow, I appreciate your help, Brain. I understand that White/Blue and Red/Green carry identical signal but it is not the question. The...

Romy, is that an SPU Mono that you have there? This converted stereo cartridge (SPU = Stereo Pick Up) has its coils rotated 45 degrees to reduce vertical sensing.
The Ortofon C Series are the genuine mono cartridges - the motor system is the same ...

Since the 2007-2008 alchemic music season and consequentially live FM season was over (the event I marked with my “End of the live Phonostage”) I have been spinning a lot of vinyl lately. So, I spent some time with different phono cables with my diff...

With the recent changes on my configuration changes and employing the “End of the Live Phonostage”, in duty I re-thinked my analog playback. I got rid to arms and one deck, changed the mapping between the arms and phonostages and ended up with quite ...

[quote user="drdna"]Romy, I think you are asking if I have the Edgar subwoofers also. Yes, I do, like giant woodgrain refrigerator in the living room. So I do get some bass response. [/quote]

The cut is the beautiful Conchita Supervia is inging Carmen with Gustav Cloez in 1930http://www.mediafire.com/?iijmy0inmmoSorry for the clipping sound – it’s recorded at +3dB at the peaks. The damn SPU with its 3mV output and the 64dB in my phono...

Brian (or someone else who knows...)-I just obtained an SPU mono today, believing it was the 25 micrometer stylus version when I purchased. In fact, it is the 65 um version. Is the 65 ONLY suitable for 78 playback, or is this thing usable...
