Phono Stage - The great analog tragedy


In the world of analog playback, there is an interesting observation. There has been tremendous innovation in the field of 
Turntable - Direct, Idler, Belt
Cartridge - MM, MC, MI
Tonearm - Gimbal, Unipivot, Linear Tracking

For all of the above designs we find some of the best reference components designed in the 50s, 60s, 70s and 80s. Most of the modern products are inspired from these extraordinary products of the past. But when it comes to phono stage, there is hardly any "reference component" from that era. They just standardized RIAA curve for sanity and left it. Manufacturers made large preamps and amps and allocated a puny 5% space for a small phono circuit even in their reference models, like a necessary evil. They didn’t bother about making it better. 

The result? It came down to the modern designers post 2000 after vinyl resurgence to come up with serious phono stages for high end systems. Unfortunately they don’t have any past reference grade designs to copy or get inspired from. Effectively, just like DACs, reference phono stages is also an evolving concept, and we don’t have too many choices when we want a really good one which is high-res and natural sounding. Very few in the world have figured out a proper high end design so far. And most of the decent ones have been designed in the past couple of decades. The best of the breed are probably yet to come.  

It is a tragedy that our legendary audio engineers from the golden era didn’t focus on the most sensitive and impactful component, "the phono stage"

No serious effort was made to make top quality phonostages to match the remaining analog innovations.

@pani  I don't agree with your opening post or this one above. We designed our phono section in 1988 and it was a year before our line section was developed; then we introduced our MP-1 preamp, which was fully differential and balanced. By your premise that fully balanced phono section didn't exist. But it did. There were a good number of very good phono sections for high end audio in the 1980s. 

I think if you examine the Harmon Kardon Citation 1 (1958) you'll see a fairly elaborate phono section for the era. LOMC cartridges really didn't exist at the time so that phono section was for MM cartridges, and it was extremely competent. 

In relation to the 50's and Phonostage Technology, the Hard Medium Embedded Data was slow to grow in large volume for the the info available that was able to be embedded. Potentially meaning, without a consistency in what to work with. meant that design was not as forthcoming as a later time when there was a stabilisation of what is to be a embedded data.

I suggest it was a time when certain individuals with a capability were unsure where to with an advancing design.

This is suggested, as RIAA is recorded in historical accounts, as being Trickled into the Industry practices as Standardized EQ, reports suggest the take up was not immediate and become more popular across years of the decade.

Then there data that enabled Stereo that arrived at the latter part of the decade.

The Question is at what time was the industry in the know Stereo was not too far into the future, as this might of been a brakes on influence.

@pindac Stereo reel to reel was available as early as 1954 using 'staggered head' format.

Good topic for discussion, thanks.  I do not particularly believe that the lack of good phono stages capable of supporting low output moving coil cartridges in the "golden era" e.g. pre 1980 was a tragedy.  The better amplifiers and preamplifiers of the day did an excellent job at cleanly amplifying the signal of the better Moving Magnet cartridges of that era, 

Aside from the Denons and Ortofon SPU (which each historically used SUTS for the first amplification stage), LOMCs did not start becoming popular until after 1980 or so.  In which case it was an analog tragedy that neither existed in the golden age.  

However the industry has since responded quite well as there are a number of very high quality internal and external phono preamps that can support the best of the best LOMCs.  I would argue the golden age of vinyl playback is NOW.  

I could never understand how many audiophiles buy cartridges that cost more than 10 thousand dollars and at the same time don't care on the quality of phono preamplifiers.
