Hi Mark,

Absolutely. The Pioneer is doing the phono equalisation; I doubt if
the input stages are anything fancy or grand - suits me if they are
using a standard design. Noise, THD & the RIAA curve should be well
under everyones belt by now. The box says it's a Pioneer A109 MOSFET
system; methinks that's the output stages with the mosfets - the amp
has a kind, full sound not dissimilar to valves.

Anyhow I'm more worried by the DAC stages at the PC end. The only
thing I can quote is that with the preamp off the SonicFury itself
gives noise c. -100dB (that's what Krecord reports), amp on gives -75
to -80dB & then with the needle on blank LP track -35db. So the noise
floor is way down there.

Audacity itself can apply the RIAA curve; there is a selection of all
sorts of curves held in table you can apply. But a simple gain stage
from turntable into the SonicFury would by me ..what? Well could do it
with a 9v battery and some nice ultra-low noise transistors I've done
with OC71's... OK, that's not funny and a few bit's 'n bobs. But the
Pioneer does all that for me anyhow.

What else? Really, I need to strip & rebuild the PL12D's barings -
there is 9Hz rumble on recordings with I'm stripping out with a notch
filter (audacity again). The deck has had no oil since ahem, um...
1997 or so when I used up the last of the fine oil which came in the
little plastic oilcan. Should get some more... But today the PL12D's
working well & I don't know if I want to disturb it; the belt must be
20 years old - it's not slipping so fine by me. Perhaps I should spend
a little on the deck...

This is all so much fun I just love it!

OK OK I'll get some oil & a belt. Hey did I just guilt myself into
that? Wasn't this about RIAA?

P.S.

I do hope you're running the turntable into some sort of RIAA equalized
magnetic phono preamp.
