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"

In the 70's I believe I bought my first Album ever which was one produced by the Monkees. The Group had probably disbanded when I bough my Album, but TV made them attractive to a young person.

In the 80's Vinyl LP Album collecting became much more intense, weekly purchases will have been common. 

In the Late 80's / Early 90's I recollect Stand Alone Phonostages becoming regualar tipics of conversation during the 90's I had a SS Phonostage commission built for me. This is still owned today and has been out on a Long Term Loan for more than 2 Years.

Nearly 30 Years Later I am having another SS Phonostage Commission Built for me with a different approach to the Spec's.

I am assured the Spec's being produced are very very high spec, whatever that means, I look only to  Power On and listen and not get too bogged down in the measurements.

My Wife worries about Valves used for Amp's, I am making available to her in her own requested pace for a System Set Up. My SP 10 MK II and the new SS Phon', will be loaned as a MM set Up with a Neurochrome Amp' and New High Efficiency Speakers. The above apart from the New SS Phon' will be gifted to her for her own Vinyl Replays when the home is refurbished and moved back into. 

I will get the 90's SS Phon' back as well to see how things have changed.   

What Dover said.  I can give you some "obvious" advantages of a full function preamplifier vs separate line and phono stages. Provided you allow for the luxury of an outboard PS for the full function preamp, I would argue that is the inherently superior configuration, all other things being equal of course.

I can think of a few great preamps from the "golden era" with good phono stages, including the Marantz Consolettes (never heard them with the "bridge") and the tube 7 (often called a 7C but the C was for the cabinet). The ARC SP3-a-1 was great in its day and there is apparently an update for it. I ran an ARC SP-10mkii for years- great sounding, but it was very microphonic.

I think the trend toward "separates" probably coincided with the advent of digital front ends- why pay for a phono stage if you don't need it? And there was a period where there were not as many phono stages marketed as there are now. I remember when I was setting up the system I have now- and trying to hunt down an Expressive Technologies step up to use for the SP-10. Pretty scarce in the wild. 

I wound up going the line stage-phono stage route. I requires an extra piece of interconnect, which is a potential downside. On the upside, I roll the power supply tube in the phono stage, which makes a huge difference in the overall voicing of the system. 

@dover your list of vintage standalone phonostage is very interesting. I will check them out one by one.

Having a phonostage inside a preamp or outboard is notional. A preamp with phono and external PSU is probably the best thing. Where I was coming from was, there was no cutting edge work going on in phono, like it was happening for amps, preamps, CD players and Turntables. In the 60s we got Marantz, Mcintosh, Quad for tube amps. In the 70s came in ARC, Naim, followed by Mark Levinson Class A, Krell Class A etc. Then there were Japanese giants like Sansui, Pioneer, Yamaha building the best of the seperates. Take any phonostage (other than the Marantz 7 which I have heard great things about) built inside these components, they cannot be considered in the same league as the remaining of the amplification chain. No cutting edge work on phono. They sound noisy and midfi.

I think your experience must be limited, and I disagree with your premise. Not to say those vintage units were better than what we have now, but only to say you might be surprised at the similarities between old and new circuit designs. We simply have better parts today and the benefit of hindsight. For one example, the Marantz 7C originally used selenium rectifiers, because that’s what they had available. If you simply upgrade the rectification, the SQ takes a leap forward.
