Master Limage,  
 
More tinkering on the counter weights. The Reed comes with two counter weights, one which is fairly light but useful if you have a heavier cartridge and other which has a dropped adjustable counterweight in 2 directions, so plenty to play with.  
 
First of all the original setting I had  
 
 
 
 
as you can see here, I am just using one counterweight, with the dropped counterweight, moved further back, this means the main holding position is moved closer to the pivot bearing but the dropped counterweight is moved further back. This is normally how I prefer it.  
 
after your initial suggestion of moving the counterweight closer to the bearing, I also mounted the smaller counterweight as you can see here  
 
 
 
Now the main counterweight is as close as possible with the dropped counterweight also as close as possible, balancing the move of the main counterweight closer to the bearing has allowed me to push the smaller counterweight into position to adjust to the correct tracking force.  
 
I find the sound more compressed, the mid range in particular looses the magic, although the treble did seem to improve .... so next.....  
 
The main counterweight only, but the dropped counterweight being positioned to get the correct VTF but at the same time pushing the counterweight close to the bearing. You can see that the dropped threaded counterweight is now flush at the end nearest to the bearing  
 
 
 
the sound improved, the mid range was better, treble seem to be there so since there was improvement, I decided to now push the dropped threaded counterweight as far back as possible, yet still maintaining the correct VTF  
 
 
 
this to me the preferred position. Nothing missing here, good air, good treble and magical mids. As far as I can remember, I have not come across many 12 inch arms which allow such adjustments on the counterweights.  
 
I think the experimentation is worth while exercise and not difficult to do. It does prove to me that the dropped counterweight serves a significant purpose, the increase in inertia probably provides better tracking, but certainly the improvement in sound is very audible.

It may pay to alter a bit the habit of having the counterweight far back. For this compliance figure, it is perhaps advisable to move the weight closer to the pivot just to minimize moving mass. That would allow the stylus to "trace" the high frequencies with greater ease.  
------------------------------------------------------------------------------------------------------------  
 
The counterweight is stock, so not a huge mount I can do, but I can set it up differently for sure by adjusting the dropped counterweight.

What a difference a day makes - Everything is back and sounds as very normal. Treble is pretty good, but it also reminds me when I had the ZYX Airy 3 which was much better in the treble region and bass region as well. The ZYX was very clean in presentation, but again it was the mid range which could not get me involved which reminded me why I kept the Temper W.  
 
After long listening hours, some minor tweaks, more VTA adjustments, loading adjustments - its really singing now. Kind of justifies why this cart was once the Stereophile Class A and the benchmark measured by Michael Fremer and even Arthur Salvatore.  
 
I don't think I have heard the Temper better than with the Reed in my system.  
 
Our analysis of the cart yesterday was spot on, it need time to warm up and break in since its long exile ^__^

After a mid morning audition of the Transfiguration Temper W yesterday with the Evil Kong, we were a little confused as initially the sound was was very rolled off top and bottom. The MIDAS Denon Paratrace performed much more detailed and balanced, especially in the treble and bass region, yet we could not ignore the lush mid range from the Temper which was still very refine. We then played a track from Bebel Gilberto, a more modern Bossa Nova record from 2000 to 2002. It sound rather thin with the MIDAS Denon Paratrace, so when we switched back to the Temper W, it was perfect, treble and bass sounded perfectly normal.  
 
Our initial thoughts are the carts have not warmed up in the cold morning start up and that the Temper damping system might need a few more hours to loosen up.  
 
Lets take a look at the spec  
 
Specifications  
Physical body: aluminum, resonance controlled  
Cantilever: boron  
Stylus: PA 3 x 30um solid diamond  
Core/coils: ultra grade SS-µ-metal square core with 7N copper coils  
Magnet: neodymium  
Weight: 7.6g  
Electrical output voltage: 0.5mV (3.54cm/s,- 1kHz)  
Internal impedance: 6ohms  
Frequency response: 10Hz – 20kHz + 1.5dB (20Hz - 40kHz) +2dB  
Channel separation: > 30db (200Hz-10kHz)  
Channel balance: < 0.5dB at 1kHz  
Dynamic tracking ability: (at 315Hz. At tracking force 1.8g) - >75µm  
Dynamic compliance: 15 x 10-6 cm/dyne  
Recommended loading: >9 ohms  
Recommended tracking force: 1.8g  
Optimum working temp.: 23 C  
Break in period : 30 hours  
 
the cartridge has a pretty high compliance especially against the Denon which is 5 x 10-6  
 
I have my tracking force was at 1.95g so I have adjusted to the recommended tracking force at 1.8g now. I have also been running the burning Cardas record for a couple of hours now.  
 
Things have improved since yesterday, not by a huge margin, but yes you can hear it. The treble still sounds rolled off, the bass is less boomy and more natural now. A tad more air in the mid range now. The Temperature in the living was 19C which is not at the optimum 23C as suggested. May be time to bring out the table lamp and give the cart a bit of a sauna ^__^  
 
Finally, I find that my current loading of 100ohm is a bit dark so I up this to 1000 ohms and it is now much better. Treble has improved.  
 
I have learn't not to jump the gun on conclusions, our systems are so sensitive, to mechanical properties, matching, fine adjustments, temperature, electrical adjustments etc we should learn to milk everything thing from what we have, rather than just chip and change - You see Master Limage we do listen, but we are nowhere as pedantic as you are ^__^

I have decided, to warm up my carts and burn in some of the new tonearms and the new Denon 103 in the funky wooden shell. The Cardas Burn in Record is perfect for this kind of application and even better it has a couple of tracks cut for MONO ^__^  
 
Why run one arm at a time or one cart of time, when you can be greedy and do them all !

Jasper my Temper W is stock, but Scallywag has a Temper Supreme which is paratraced and sapphire cantilever........  
 
more testing to be done on the Temper, as I will use my Cardas burn in LP to see if the damping system will open the cart up more as extensions are a bit rolled and I have not played it much - but mid range detail and richness is just sublime.

I think the US price for the Artemis is USD 3000 - very reasonable. I heard this arm at Uwe's house and he had the Schroeder Reference before which I heard last year. The difference is not subtle and all his friends are now off loading the Schroeder Reference for the Artemis. What is interesting is how the materials are incorporated in the arm, the bearing housing is a special material of compressed fiber, paper and oil - something which has no name outside the German Language, in fact Uwe showed me a Denon body made from this material @[email protected] incredible !  
 
The counterweight is in two parts, the bottom part can be turned clockwise or anticlockwise allowing you to tune the sound, I guess its like a micro VTF.  
 
Like I have mentioned before antiskate does not become an issue when you are tracking beyond 2g, so Mr Schroeder is more precise at 2.3g.  
 
Cartridge used was a very old SPU nude from the transformer period, ebony headshell, ruby cantilever and fine line tip. When I auditioned this setup, it was really hard to fault.

Diawok, the Artemis is surely a simple and elegant design, hopefully the asking price is not that high!  
 
The specs:  
 
The pivot to spindle distance is 222mmv  
 
The offset angle is 23°  
 
Overhang is 17,3mm  
 
Effective mass is 14gr with the Certal cartridge mounting plate, plus 5gr. with the pressure treated brass plate  
 
Neutral balance arm, no change of VTF when altering VTA or record thickness.  
 
Friction free magnetic skating force compensation(for up to 2,3gr. VTF)All parameters adjustable: VTF, VTA, Overhang, Offset angle, Azimuth, Anti-skating, Effective mass can be altered.

>What's Talea, Kong, an espresso machine? <  
______________________________________________________  
 
Morning Limage,  
 
According to the designer: “The name "Talea" is an homage to the late French composer Gérard Grisey, who wrote in 1986 a musical work for five instruments named Talea.”  
 
You mentioned how hard it was to fine tune the A90 on the Audiocraft arm, this Talea is just perfect for you!  
 
While it has an effective length of 10.35”, due to the offset design, it has a mounting distance similar to normal 9” arms. VTA adjustment can be done on the fly, and more importantly, it is the only arm (as far as I know) that offer azimuth adjustment on the fly!  
 
Now, you can have this fabulous arm for a mere US$8,000, what more can you ask for? :-)  
 
BTW, the designer uses the A90 as the reference, so they are the perfect match!

I searched the net and found some comments about the Temper W being a bit “dark” in sounding, as its high was a bit less extended comparing to some other top MC’s. Do you feel the same?  
---------------------------------------------------------------------------------------------------------  
 
I typed a load of crap and it has disappeared ! PK !  
 
ok start again ........  
 
Yes I agree with those comments. The Temper W's strength is definitely not the treble region. In fact the MIDAS Denon Paratrace is better and the A90 is better still and I guess the top of the line Colibri is even better. I do feel the Temper W mid bass rolls up a tad to give it the extra body and warmth in the mid range, but yet its refine and smooth. I doubt it is easy to find a true balance in carts, but I do love this cartridge's way in portraying music - emotional engagement.  
 
with regards to the Talea, I have an interesting story about the RMAF shootout between this arm and the Schroeder arm. I believe the Talea is being sold by TTweights. 3 of my friends were at the shootout, 2 from the and 1 from Germany who happens to be Uwe (Frank Schroeder's buddy). Now from the off, TTweights did their sales spiel .... can you heard how dynamic, can you hear that bass, it is much better ...... this was to set the tone and minds of potential buyers and reviewers. It can tint some audiophiles easily. Uwe then spoke out and said ok, lets play this LP - his own copy of Freidrich Gulda 'as you are' MPS label Jazz LP playing a grand piano - (I happen to have this LP as well) - according to Uwe, what you look out for is the scale of the piano, size and the bottom bass. After playing the TTweights, guy then insisted - there you go Talea is much better ! but Uwe said, no, the Talea has a rolled off bass line, the Schroeder is more detailed, more extended more accurate and the treble is not as harsh. TTweights was not happy and you can hear those in the audience discussing the difference and quietly agreeing that Uwe was correct......  
 
.........roll on a couple of weeks and the shoot out in on Audiogon - apparently (I did not read this) .....TTweights starts posting saying the Talea is much better than the Schroeder arm - even Frank agrees ! ...... embarrassingly Frank posted back saying, no I did not agree and please do not quote my name ........ I cannot find this posting, may be it has been deleted.  
 
The market uses the internet now as a means of gorilla marketing, it always hard to detect what is good or bad, simply from forums, unless you know the gears they are using. I am lucky that our good friend Jasper has loaned me to try out the Reed, and lucky to have enough carts to do some matching up. Sometimes having the most expensive of everything does not mean the best.  
 
One thing I can personally guarantee is that I heard the new Artemis Schroeder arm and it beat the Schoreder reference to my ears !  
 
This arm is understated and one of the best I have heard regardless of price.

Limage,  
 
This is a very positive review, written by a member of David Chan’s audio group, on the Artemis Lab TA-1 tonearm. According to the review, it is at least on par with other top arms costing 2 or more times more!  
------------------------------------------------------------------------------------------------------------  
 
I have champed about this arm in the past and I have personally heard it as well. It is a very fine sounding arm and super value which is like around EURO 2000 I think. In terms of arm length, most German companies prefer 10.5 inch. ...... why ? well it can be accommodated on smaller foot print turntables.

This is a very positive review, written by a member of David Chan’s audio group, on the Artemis Lab TA-1 tonearm. According to the review, it is at least on par with other top arms costing 2 or more times more!

回覆 (1984): 一人有一個夢想!
Why is it that the 401, which was supposed to be an upgrade over the 301, has never gained the affection of Garrard fans?  
 
In what area did it fall short?  
-------------------------------------------------------------------------------------------------------------  
 
The 401 came in 2 generations. The one in the 朋友 posted is the second generation 401 as the strobe protrudes. This was the down fall of the Garrard as they started to cut costs with the 401 2nd generation.  
 
The first generation 401, I had 2 - kong is right that the 301 is more collectible, especially the grease bearing with rumours at the time saying the motor was more powerful as it was a grease bearing - this was bollocks as I have serviced every type of 301 and the bearings and motors are all the same. The only difference was the platter.  
 
So how does the 401 fair in sound with the 301 ? well the 401 to me sounds better (first generation), but to me this is because the bearing is less worn and the idler wheel is less worn. You get the sense the sound is a tad more refine and more dynamic, but I am sure if you have both 401 and 301 serviced properly, there will be very little difference between them.

I guess the look has something to do with it. The 301 just looks more classic!

if the turntable doesnt turn clockwise. Instead, it goes anti-clockwise. With everything else remain unchanged. There will be no force pulling the arm towards to spindle. The force will be reverse making the arm goes out of the record. Right?

I would have thought so.  
 
But this question is better answered by our resident engineers. There are no less than half a dozen well qualified mechanical engineers around us.

> Then how to explain the phenomenum that a zero anti-skating stylus/tonearm moves towards the center in a spinning flat smooth grooveless test record .  
 
a) the straight line joining the stylus and the pivot of the tone arm is not tangential to the record groove, resulting in a sideway force which is a component of the FRICTION (dynamic) between the stylus and the vinyl

you will start from the spindle and play the records backwards but of course, the cartridge should be mounted from front to back !

If reading Fig A, the record spindle should be somewhere between A and E dotted line. Assume if you can locate the arm pass beyond this dotted line A and E. The arm would no longer being pulled towards to spindle. It will go out of the record, am I right?

I guess it is basic physics on forces, or rather the resultant force created by the offset angle along with the overhang. This resultant force is something I have never fully understood ever since the school days. My sailing yacht operates under more or less the same principle which drives the boat forward against the wind in stead of dropping back. In calculating this resultant force, I usually have the arrow going the wrong direction!  
 
The moral behind, however, is that you don't have to be an expert in calculating the resultant force. All you need to know is how this force can be applied or deployed and in this particular case, neutralized.

' b) the record groove pushing against the stylus --- due to the spiral motion of the record groove which pushes the stylus towards the center of the record as the platter rotates '

Anti-skating is needed to counterbalance forces due to:  
 
a) the straight line joining the stylus and the pivot of the tone arm is not tangential to the record groove, resulting in a sideway force which is a component of the FRICTION (dynamic) between the stylus and the vinyl  
 
b) the record groove pushing against the stylus  
 
Centrifugal force is negligible since the angular velocity of the stylus/arm assembly is almost zero.

I think it is not the same situation. The subject in the merry go-round/washing machine moves in a circular fashion. Whereas the stylus moves in a tangential straight line

' So if the same applies, shouldn't our antiskate be pulling the arm inward to compensate instead of pulling out to make things worse? '

I think it is not the same situation. The subject in the merry go-round/washing machine moves in a circular fashion. Whereas the stylus moves in a tangential straight line in case of a linear tracker, thus no antiskating needed, and an arc in the pivoted arms where there is centripetal force as there is angular motion .

Back from dinner, & did have a couple of drinks, so pls spare me if the following sounded from one who is drunk.  
 
Smoking in front of the washing machine, you gents know me, with clothes spinning, all of a sudden, audiophile syndrome kicked in. LP playback, or simple physics, centripetal vs centrifugal force. Remember the old days when we were having the merry go round, obviously our feet were receiving centripetal or inward force because of friction, but on the other hand, if memory serves, or action & reaction by Isaac Newton, our body was facing centrifugal or outward force. So if the same applies, shouldn't our antiskate be pulling the arm inward to compensate instead of pulling out to make things worse?
