No test record, what would you recommend?
I checked with protractor (two point) today and all seems fine.
Arm cart geometry I don't know how to test .
Sorry to hijack , this has nothing to do with the Simplistic pre amp, I'm sure that preamp is just fine.

Get the HFNRR test record. Its very revealing of antiskating bias, high modulation tracking, cart-arm resonance etc. Have you got too much treble in general, or is it of transient nature like sibilance only? Have you got any magnification means to check the diamond isn't grated or chipped?

Instrumental music sounds fine, no extra hi range or it is less noticeable so it is no problem.But on some vocal inclusive vynils it really gets anoying.I'm sure this sibilance is not product of the preamp, yet I don't know where to look for the cure any more. Apart from the preamp, what else can introduce this nasty distortion?
As far as I understand 100n cap in the preamp is not part of the RIAA, it is just DC block?
Thank you
I have noticed poor record quality in the sibilance (vocals) of modern vinyl records these days in the USA. Adele21 is unlistenable to me. I took it to my local hifi shop and played it with a $10,000 turntable/arm/cartridge, Ayre pre-amp and power amps, Wilson Audio speakers. Could listen to it there either.
Try an older recording and see what it is like.

I would not say that there is too much treble in general- not at all. Instrumentall music from jazz to dub step- sounds just fine. It is sibilance of transient nature only. No magnification means, just 5 times lamp thing...

Interesting device to check solder joints & pick-up cartridges.
