The Sentec is mono - however it can be used with mono modern cartridges and stereo setups - it has two inputs and two outputs. Via a toggle switch, you can use it for true mono, with the outer groove wall (typically the less damaged one) for preference.
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.
