Haha, I've never heard any Naim gear so can't comment but I totally agree about the waveform.

Hi Oli
The last time I saw a waveform similar to that is was pretending to be a broken output FET.
This is very basic principles here, imagine trying to reach the far side on the moon on a 50cc Vespa, never mid breaking free from the Earth's atmosphere just trying to hot 35mph would be a bloody miracle!
If a Moped constantly did 55 mph over 24 hours, it would get to the Moon in a 180 Days.
Obviously it would need a little assistance, like maybe a road to make this a reality.

I could point out save is a vucuum and no air s n combustion but sorry off topic
Suspect Aan has managed to rectify to basic problem quite easily
Sooo, back to the Valab :)
Its been left on for a week and had probably 15-20 hrs of records playing. I've spent a bit of time fiddling with the settings and so far the Fidelity Research FR-1 Mk3 that's currently hanging off the Bergmann seems to prefer 200 ohms and a gain of 67 db. Quite pleased with it tbh, regardless of the money it sounds pretty good so far. Very very quiet.
Next step is to experiment a bit more with different gain settings, and then have a go with the MC head amp set on zero gain and the Valab at MM output. There's 4 impedance settings on the H-Z1 to play with inc 470 ohms to compare.
If you put a square wave through an RIAA network surely that is what you'd expect?
Otherwise, what exactly do you think it should be doing with the high frequency component of the waveform? If it let it through unaltered it wouldn't be much use in eq'ing the output from a cartridge playing a record.
Here's an Aurorasound Vida reproducing a 1 KHz sine wave.

and here is the same phono stage applying RIAA correction to a 1 KHz square wave

That's what it's supposed to look like. You need to remember what a square wave actually is.
