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"

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!

I have heard the McCormack phono drive (not the modsquad deluxe phono designed by him). It is good. But it still sounds like a well done $1000 phono of today. An EAR 834p kills it in the same system. 

Subjective Assessment ( Evaluation or judgment that is based on personal feelings, opinions, and experiences rather than objective facts or data).

Subjective Assessment used by myself when encountering a 834p as a EAR Design or a Variant Clone Design has never been an experience where I feel compelled to make an inquiry about how the Model is produced and learn how to acquire a model. In my assessment, there is not a end sound produced that generates an attraction to myself, that is wanted to be pursued for being available as readily at hand to be used.  

Does the 834p fill a room with Sound that is able to be listened to and not wanted to be avoided? Answer is Yes.

The subject of Phonostages and only giving the designs credit as a result of subjective assessment, is going to produce a mass amount of models to be suggested. 

Objective Assessment (A method of evaluation where the questions or tasks have a single, clearly defined correct answer. These assessments are fact-based, unbiased, and measurable, minimizing subjective interpretation. They are often used to gauge knowledge, skills, and understanding of specific facts and concepts).  

As stated by myself in an earlier Post and now with a edit:

" It seems those with a Proper Understanding of the Math will be best placed to give the best advice as to what a Phon' can aspire to be today as a finished design. In relation to the measurements values that can be taken from a modern design and measurement values that was not possible to be taken when produced during eras 20-50 Years in the past."
