we all know that playing old records you should use old equipment (e.g. tube electronics) and for new records you better go for modern equipment!? No? Okay! Why did the EMT studio engineers use different settings at their inbuilt transformers/pres when playing old or newer records? Maybe you do not need throwing away all your units when having ended up with modern tables 🙂
But you should rather concentrate on the preamplication path than pushing the last high frequencies via your cart.
If you feel something is not in the best way reproduced as you have listened to the last time in a good chain it might have been that you are using a RIAA curve on a Neumann cut record, as most of the today´s cut vinyl is done by.
using the correct curve of the recording process supports a stable and perfectly reproduced signal, especially in the high frequencies area (see also “Equalization Curves” on AudioCirc.com).
How does this come?
In the 80ies of the last century a so called enhanced RIAA curve, the E RIAA or Neumann curve was established. Before we had with the RIAA curve no offical upper limit. As most modern systems have far wider bandwith than the old tube electronis (sic ! ) during the cutting process many lathes were destroyed due to high frequency roll off above the audio band (>20kHz). The recording engineers` answer to this problem was a simple technical process by using a few components only – and bringing in an additional time constant at around 35 kHz. When reproducing this complementary correction one should have an inversed lowering of the “RIAA-filter”. Using the old RIAA norm you lower too much on high frequencies.
Whoever does not hear these effects or telling me this is a kind of gimmick which no audiophile needs at all should try using a proper Neumann curve setting on his preamp or phono-preamp as the EMT JPA-66 provides.
In today`s High-End Audio World I usually meet three kinds of audiophiles:
Type 1: The Listener, listening and enjoying the good sound, technical details are not of great importance
Type 2: The Testing Junky, listening critically, the technical details he does not deeply understand but he likes talking about
Type 3: The Historical Man, listening critically, he does accept only units produced before 1930, everything else is modern shit
ah – I forgot all our friends writings in Forums (maybe I belonged to them too :-), he knows everything, even if he has never seen or listened to the product— now you may start stoning me… in case I forgot something…
