I am taking the opposite route. I've got only one set and I cannot but focus all my efforts to get it optimized.
------------------------------------------------------------------------------------------------------------
Don't get me wrong, I am also very focused ! ^__* may be time for you to experiment Master Limage - I got plenty of artillery for you including the Reed !

This actually leads me to think that it is NOT so much the tracking angle at play, but the sweet spot of the bearing system of the tone-arm that is affecting the performance. When you change a cartridge, you have to adjust the arm until it clocks the same sweet spot of the bearing to get the most from the new cartridge. Uni-pivots have got a bearing which is so small that it can be largely ignored, perhaps!
-----------------------------------------------------------------------------------------------------
I think it is true that its a combination of things, arm, bearing, tonearm cables, setting up, VTF, VTA, Azimuth etc etc. Yet all these things will change as some records come in different thickness as well. However, I am not too sure that a unipivot with a small bearing has more advantage or lesser advantage, its just different. With all tonearm bearings its all about reducing the friction - to allow free flow - that balance is also hard to achieve as the worst culprit of friction is in fact ANTISKATE ! the dragging force on pivot arms is probably higher than any force a bearing would engage, yet you use a Antiskate to compensate purely on trial and error and guess work. The rule of thumb as I recall is that Antiskate is 10% of tracking force, where it comes from I don't know. Tracking force from 2g up wards requires no antiskate - correct me if I am wrong.
I can argue to say Linear tracking is superior as it takes away the antiskate issue, but of course not all linear trackers are the same and they too have their own problems.
The key for any setup is to milk out as much as possible in terms of getting the right combination. This is the very reason why I have a number of tonearms and a number of carts, experimenting and hearing what makes them sing ^__^ |

When I was using the SME 3009, VTA adjustment was indeed a hair-splitting exercise. And yet when I switched over to unipivot, can’t remember how many years ago, this VTA thing suddenly became a snap. Believe it or not, it doesn’t have much bearing on board a unipivot.

| BTW - the VTA / SRA on the A90 is super highly sensitive ! I spent over 3 hours just tweaking this at the Wicked Den. |

Well, azimuth is something of a controversy among tone-arm designers. Some pay no attention to it, like designers of the SME V while a few would take it to the other extreme to even designing elaborate devices to enable azimuth adjustments on the fly.
I must admit I take azimuth quite seriously, more seriously than say, the vertical tracking angle. It would normally be the final item on my fine tuning process and it is likely to take more than an hour.

Master Limage,
You are totally correct. The first guide here is to get the body square as a reference point - this means for both azimuth and VTA which is why the MIDAS BODY is so square ^__^ after which from these reference points, you make your necessary adjustments to ensure the stylus is square in the groove, the readings on the test records or computer readouts and of course human ear are correct. The SRA however is another kettle of fish, this is purely done by hearing alone IMHO. |

Imho, azimuth does not mean that the cartridge simply sits squarely over the record. If that is the case, arms do not have to cater for azimuth adjustment at all as long as the headshell is kept sufficiently horizontal.
Instead, it is the stylus tip, or more precisely the two sides of the diamond, which should sit squarely over the groove valley. Mind you, diamonds are rarely cut symmetrically and therefore we’ll have to twist the cartridge askew one way or the other to achieve true azimuth. It is the points of contact between the groove and the stylus tip that account for the kind of data we get from this rather primitive mechanical transmission.

Nice photo, the Shiny Midas can help in azimuth adjustment no doubt. Seems the arm is of rather than the Midas Body @[email protected]

Another shot of Midas Touch. Not a patch on the B&W masterpiece shown earlier but i hope the maker will enjoy it.:)
On closer look the Azimuth appears to be a bit off. Bugger. :(

If I were Denon, I wouldn't accept this picture which lacks much details of the cartridge!
The photographer must do it again, I am afraid.

The only good Denon 103 is one without the plastic body. No need to see any details of the cartridge..lah. ;)
Fantastic pic btw. |

The Mercury original MONO version this album is certainly very very good. I recently missed out buying a Japanese pressing Mercury MONO of this very Album. I am still hunting for serval pressings but some are way beyond me ......
check this out !
This Cannonball Adderley - Somethin' Else just sold on Ebay for a cool USD 317 !
However there is also a buy it now available for USD 549

Now ..... start looking at your MONO collection as they could be worth more than STEREO.
In fact the Bluenote Japanese MONO are worth a minimum USD 200 each !

Very true Master Limage. The early Tannoy's, Lowther and QUAD ESL 57 were made for MONO systems.
However, my current MONO speaker is in fact not a horn, nor is it big in the scheme of things. The main driver is only 8 inch, yet the bass is good enough to satisfy most enthusiasts (up to a certain extent).
Do you have any MONO recordings ? it might be worth while to hear how it sounds through one speaker, it is was meant to be. |
