Dear friends: Here are some facts about why exist the SUTs for LO cartridges ( at least is my point of view ):
- In the fifthies appear the MC LO cartridges ( As a fact: Ortofon invented in 1948. ). In that time all the phonopreamps were designed for HO cartridges MM/MI/etc. No one was in the design of high gain PP because no body need it.
- Ortofon and latter other MC LO cartridges never ask to the PP designers/builders to manufacture a high gain PP for their MC LO cartridges. What I mean is that never exist a cooperation job between the MC LO builders and the PP manufacturers.
- What was the comercial attitude of almost all MC LO cartridges builders?: to put on sale their MC LO cartridges along with a SUTs ( designed for it self ) for those MC LO cartridges.
- I can remember from Ortofon when they design the MC10, MC 20, Mc 30, Mc 2000, Mc 3000 and MC 5000, cartridges at the same time they offer the respective SUT: T 10, T 20, T 30, T 5000.
- Like Ortofon everybody do the same: Denon, Audiocraft, Fidelity Research, Koetsu, Micro Seiki, Accuphase, Dynavector, Highphonic, Audio Technica, Entre, etc, etc.
- In the mid-time what does the PP designers ( SS or tube ) for the development of a high gain PP?: almost nothing, almost all take the easy " cheap road " ( wrong/worst one ): that the customers buy SUTs along with their PP if they want to handle a LO cartridge. Some of the PP designers/builders incorporate in their " high gain " PP internal SUTs, exactly like today ones.
- No body take the challenge to design a HG PP with out SUTs. There are some exceptions: Curl, Levinson, Pass, Klyne, Classé, D'angostino, etc, etc,
- So we all are suffering the " easy road/ wrong road " that almost all designers/builders take it more than 55 years ago.
- All those comercial attitude never take into account us: the audio customers and never take into account the QUALITY MUSIC/SOUND REPRODUCTION. They don't care about in those times and many of them don't care about today.
Fortunatelly, in the last few years, some PP builders finally take the challenge ( others like me designed our self ones ) and we have some very good HG PP, many of them at very high price.
This change of comercial attitude: Bravo!!!!!!, could tell us that the best about is coming because the developtment of HG PPs are really " starting ", it is not a mature industry.
Regards and enjoy the music.
Raul.
