Yip ferzackerly Cj. I just dont get this fixed or faff around vta mullarky.
@Drummerman. Quite a fair amount of mega bucks coils are way out of that 2 degree 'quote'. Couldnt think of the worm I wanted to use (still cant) so precision will have to do.
Edit. Sensitive ! thats the badger, absolutely nowt like precision ,lol.
Edit 2. A vast majority of carts these days measure way above 22 degs , more like 30 degs. Now then , basic trig will tell you that you need to adjust the arm height 30 odd mm to get down to 22 degs (depending on arm length obv) pretty much out of the question with most arms I agree. 2 degs is doable if you can adjust your vta. Would it alter the sound , well you never know unless you try *. If Mr Gandys quote is correct I'm prone to think he said as much due to the fact he didnt give vta adjustment a second thought " who is going to notice a 2 deg sound difference either way " , we will never know I guess, but he is in a minority of probably 1 where vta is concerned. On saying this even at 30 degs most carts these days sound pretty damn good , in theory they shouldnt, but they do, go figure.
But it hurts nobody to tweak the settings, I'm with Cj all the way on this.
* If one needs to go really a**l about this , certain camps (not me I hasten to add , well not all the time,lol) alter the vta if the vtf has been changed.
Best not get into vinyl springback eh ,lol.
Have any of you young turks invested in a headshell spirit level ?. Probably the most usefull 6 or 7 quid spend out there.
Ok, a-tweekin' I will go...tomorrow, after the sauvignon blanc has worn off
I'm already at the 3G setting for the rega arm, so no spring tension, so will see how my Benz sounds at 1.8-2.0g downforce range by adjusting the counterweight only. (currently at 1.65g according to drummerman's scales).

I suggest that you set up to the lower setting ,have a listen,then the higher setting. You should hear quite a difference between the two. Then away ye go tweaking. I'm guessing that your arm is devoid of vta adjustment ?. If so thats a pity because you can also play with a**e up or down at the counterweight end , tweaking this can have a profound effect too.
If you dont feel very confident about all of this i.e fear of bouncing your cart, then buy a cheapo clunker to mess around with.
Probably best to get an arm/TT that allows easy VTA adjustments to be made 'on the fly'. Then you can make a little data sheet (kept in each LP cover) of the optimum VTA and VTF settings for every album.
Or buy a good cartridge with a conical or spherical stylus. (Then the profile 'presented' to the groove won't vary with VTA.)

Wowsie ,I trust that your tongue is well and truly in cheek here Chebby ?.
However , maybe of interest to Rega owners with a bit of cash to splash regarding adjustable vta. J7 (Audio Origami) is now doing his PU7 with the three point mount.

Sort of but not quite.
Back in the day (mid 1980s) a colleague of mine had a giant, top of the range Philips 'Black Tulip' rack system that he bought when working for them in Eindhoven. It included a graphic equaliser with about 12 sliders per channel.
Everytime he bought a new LP he would spend hours tweaking all the settings until satisfied it sounded as good as possible. Then he would write down all the settings from the equaliser and fetch one of his card 'templates' (he'd got them printed with numbered grids corresponding exactly to his graphic equaliser sliders) and cut - with a scalpel - each slider position for that particular LP and file it in the LP cover.
So when he wanted to play that LP again he would push down all the equaliser sliders to their minimum positions and rack them all up to their 'correct' settings with the template. (The sides of the templates all had 'reference' marks on each side to correspond to the middle or 'flat' setting so he could ensure accuracy.)
I'd never seen anything like it before or since.
I've previously rewired the tone arm with Incognito pure silver rewire (single wires through to amp, with separate grounding wire, which got rid of hum in left speaker)- which was extremely fiddly, so ready for the task ahead!!
It's also got the Origin Live counterweight, white drive belt, alloy subplatter with ruby (and the Inspire "full monty") ... A highly pimped P3-24
Ok Dandy ,sorry if I sounded patronising .
Crikey Chebby ,good read that deserves a double Wowsie !. Did he ever go out into the sunlight, ha ha.
Not at all Floyd, killing an £800 cartridge is not worth any unprepared tweaking.
Did a bit of a play this afternoon, using my sennheiser hd650 headphones to remove the sound of Sunday lawn mowers and car alarms
Put Beck's MoFi "Sea Change" on the platter - I know it well and has a good range of very high notes (xylophone I think), midrange vocals and acoustic guitars, and underlying bass.
First took the downforce to 2.03g - bass was much stronger but the high notes seemed clipped and a bit drowned, without much air or sustain.
Then took it down to about 1.85g - a little less low end, but the high notes really sang.
Came off headphones, and the sound at 1.85g seemed much better through my B&W CM8s than I'd had at the original 1.65g.
Anyway, this is how it sounded to me - I don't have the hifi wine-tasting vocabulary so can't describe gooseberries gushing up my nose, but adding the extra .2g seems to have improved the sound for my ears.
I wouldn't have experimented without drummerman's £6 scales. thanks Mr/Ms D!
Perhaps my stereo speaker cables (chord carnivals) might be next for the experimenting.
You will hear differances at 1.86,7,8,9 and 1.9gs. DC, trust me, that fraction of lost bass may not be lost? As Floyd says, VTA is your next step, forget cable for the time being, expensive way to go, IMHO. Three point shims are avaliable on 'the Bay', a set of three at '1mm,1.5mm and 2mm', costing around £20, mix and match up to 4.5mm!. The Benz stands higher than a Rega cartridge, so shims should open up a new world of musicality?
PS Make it a little easier, try 0.02 increments.
Aahw ... you're welcome. I've used mine to good effect too on both tables.
As to shims and VTA, I guess it is, to some extend, stylus dependant. In your case, an expensive cartridge with fine stylus will probably respond to VTA changes but as a lot of vinyl is of different thickness I guess finding a medium is the aim but I'm sure you know all this better than I do.
One of these mini bubble level things for azimuth as mentioned by floyd makes a lot of sense and I have one on order. One thing that can be adjusted accurately without to many variables.
Pretty ... and pretty proud of it
My Benz was fitted personally by Peter from Alternative Audio - recommended by cjsf.
Peter worked with different three point shims to get a horizontal tone arm. The cartridge seems closer to the vinyl (only about 1.5mm above) now that I've increased the downforce.
I'm new to all this and my knowledge of cartridges is restricted to the three I have. They all track in the same weight range but both Shure's are riding higher over the vinyl than the Ortofon which is really low, perhaps a milimeter at 1.25g and slightly over at 1g. However, it tracks faultlessly, the cartridge body doesn't touch and it sounds good.
The cartridge plays really well, so I suppose I shouldn't worry.
