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"

I’m going to add to the chorus: there were MANY great phonostages in the 1990s. That was when designed separated the linestage from the phonostage. There was Tom Evan’s Groove phonostage, Audio Research has had phonostages since the early 90s, Mares, Musical Surroundings Phenomena. And I owned a Vendetta SCP 2A back in 1992.

I’m thinking you’re very young, or you came into the audiophile community in the 2000s. That must be why you think phonostages only came of age in the 2000s, but clearly, as you can see, that was never the case.

I was very impressed back in 1980 when Crown international came out with the SL One preamp which came with an adjustable input sensitivity adjustment for different cartridges gain characteristics. A great idea for a $600.00 preamp. Not many other manufacturers did that in that price range. For about 5 years, they made excellent best for dollar Hi Hi. Mine lasted 45yrs, (PA and Pre A.) sounded great. Retired because of worn switches, older components. Carver was also a great deal back then.

There were/are a number of excellent phono stages out there.  I have a Vendeatt that I had John Curl update and it has compared very well against more current Herron units.  Other older designs like the CJ Premium 15 and the on board stage in preamps like the Classe DR7 also hold up very well - I own both and so have had the opportunity to compare. 

As a 2 1/2 decade owner of a modded Marsntz 7C (following personal guidance from Saul Marantz for the modding!), and a greater than four decade owner of an Audio Research SP6B with lots of experience tube rolling in both, I am intimately knowledgeable of their sound.

That said, the performance of modern separate phono preamps and line stage preamps together far exceeds the performance of both models as either line stages ir phono preamps. I began to understand this when for kicks, I subbed my little Schiit Saga preamp (with a Sylvania “Bad Boy” 6SN7) for my SP6B and heard more resolution. Shocked me- the “palpability” of instruments, the air around them, wasn’t quite as well produced but it did better pretty much everywhere else. 
I don’t have the best phono preamp- it’s a Hegel V10- but it’s ability to easily change loading (as opposed to in the SP6B only be able to change a resistor by soldering with the cover off, along with the inability to change loading capacitance, and only a one step gain switch that in high gain didn’t provide enough gain to support anything but high output moving coils) made the Hegel a far better match to modern phono cartridge design. It elicits far more information from the record grooves, partially due to better phono cartridge loading flexibility.

I truly loved those Marantz7c and SP6B preamps, but my Hegel/Cary SLP05 combo is on another level. Now I just need to replace my Grace 707 tonearm with something friendlier to medium and low compliance cartridges!
