Is RIAA equalisation enough for Phono Stages?


This question was bought up in the latest HiFi+. In particular, the editors report back from the Dem he put on at the Rocky Montain show. To summarise the argument, he says that even after all companies signed up to use RIAA in the 70's I believe, in fact they did'nt. The poor results from DGG in particular, with screetchy, painful treble, is all due to this. Played with the proper correction, they are transformed.
Now a number of stages, both cheap and expensive, provide alternative equalisation, but not all, including many expensive ones. I believe Graham Slee at the cheaper end, EAR, Manley Steelhead, Zanden, all do, for example. Should it be a more important considerration in choosing a stage? Looking at discussions on this site for example, it does not seem to come up much.

Patrickamory, wow Tone Imports. They also import the EMT JPA-66, which I have heard. It gave a major improvement on the early LPs, such as the early 1950s, and 78s. It probably is more expensive than the Sentec. I just noticed that the Sentec is mono. Do you have two, or do you have a mono dedicated vinyl source?
EMT had a phono stage at the last CES with many choices on equalization of records. One listen to it suggests that you need more than RIAA. It also works for 78s.
Patrickamory, Loricraft has an inexpensive phono stage with many choices for equalization. I have not heard it, but had their standard model which was very good for the money.
Patrickamory, can you tell us more about the Sentec. I have not heard of it, nor can I google for it.
When I had the Win strain gage cartridges, I understood why there was no need for RIAA, but I no longer recall this. Does anyone know why? Also, I remember Sao Win demonstrating the Stax CPX cartridge at CES. It was far and away the best vinyl sound I have ever heard for the cut and a half on one side of a LP that it lasted.
