Cheers for all the responses guys Much appreciated!
Just to give you a bit more info on the situation:
Yes - I have got the phono stage input set to Moving Coil I may look daft & quite frankly can be sometimes but not in this case...
Pivot to spindle distance is 222mm as per Rega / Moth instructions.
The manual for the pre-amp only specifies 47KΩ input impedance.
The Ortophon Bronze specification states recommended input impedance to be 10Ω to 200Ω
I'm led to believe that 47KΩ an an arbitrary industry standard but I have no idea whether this is just for MM or both MM & MC Please enlighten me on this.
Obviously there's a pretty huge difference between 200Ω & 47KΩ.
I can find no info on whether the MF steps down the impedance when switching to MC If anyone knows wether it does please let me know.
I'm pretty au fait with impedance matching having worked in the Space Industry all my life as a microwave engineering technician and realise how important this factor is.
Cartridge tracking weight is 2.3 grams Bang on Ortopon's reccomended 'ideal'
Null points exactly match the arc defined by the Rega Baerwald protractor I have.
There is absolutely no lateral movement from the Gyrodec even if I give it a fairly huge 'Bounce'.
I have no equipment available to even remotely accurately measure the azimuth.
But as all other parameters appear to check out I'm going to assume that this is OK too.
There are also two rather contentious issues which to my mind are VTA & Run-in / Burn in times
Opinion on these two issues is fiercely debated (as you are almost certainly aware), & way beyond the scope of this thread.
However ...
As for to VPA I can only refer you to the rather excellent article:
http://www.tnt-audio.com/sorgenti/vta_e.html
Run in / Burn in times I personally believe are an important factor because I believe my own ears & also that of my best friend + whist running in the Gyrodec I've not been amplifying it Just putting the Prodigy's Music For The Jilted Generation on repeat & checking once a day (ish).
So there is no potential for my ears to adjust themselves to the sound I'm hearing.
The stand everything is mounted on is 40mm solid oak made to my own specifications by a good friend who is a professional joiner. I can give the rack a right good thump & the Gyro doesn't bat an eyelid.
I'll add, by way of an aside, that I've played guitar for about 30 years & have been in many studio situations & know good from bad sounding set-ups. In short I trust my own ears & can tell the difference between a Les Paul & a Stratocaster or a transistor guitar amp compared to valve amp.
As for the 'Hodge-Podge' recommendation I rang the local council this morning & they're delivering a skip tomorrow morning
Thanks once again guys.
