Hi,

on the basis of the renewed thread energy, I did some A/B comparisons with one of the 103 antonym (sp?) the ADC XLM-III (with standard stylus) and went back to the "R". It is remarkable how close these two options are to one another, despite the different operating principles! Still, the XLM-III, and the "R" are far from the basic iterations of each design. But the ADC Astrion stylus shows one additional degree of refinement.

Just fo the sake of it, I removed one 3-gram headshell ballast from the "R" and left just one in place. That makes an extra 3-grams added to the normal SME 309 headshell.

This raised the LF resonance from 8+ Hz to 9 Hz. Additional testing confirms that this setup works better with just one added ballast, and with lower Antiskate ( down to 1.5) in contrast to its 2.5-gram tracking force.

The "R" also tracked 100 microns of 315 Hz on the "Image HiFi"Test LP #003 with the 1.5 AS/2.5 TF combination cited above, and the "King James Version" big band on Sheffield Direct To Disc, with true-to-life musical colors.

Truly good,

An interesting thread about a wonderful cart. I don't have the R version, only the basic 103, and it does have a way of delivering what really matters from the record.

One thing I did notice when I installed my DL103, (and I only own the one), it's absolute polarity when hooked up according to the supplied instruction is the opposite of my other carts. It is opposite to my Glider, AT OC9ML II, Shure and Clearaudio carts. I soon noticed this by ear and also confirmed it later looking at some wave forms. I need to reverse the blue/white leads and the red/green leads in order to bring my 103 in line with my other carts. I need to do the opposite of what it shows in the pamphlet:

I don't know if the R version shares this polarity trait with the regular 103, but I would assume so since the design is so similar. Some people can hear changes in absolute polarity and others can't.

Hi spiralfool,

the pin orientation on the "R" version is the same as your regular 103. No change. Your observation is interesting, but my results are so good already that I am not willing to suffer through a very uncomfortable and cramped procedure caused by the bulky cartridge body.

Regards,

I was thinking polarity when I read what you had written about the DL-103R on a particular record:

"As of this moment, I did a comparison of one LP side on the DL-103R, and on the Stanton 881S. This particular LP side has lots of Beethoven massed strings ( 3rd and 4th movement of Symphony #4) which came out more naturally and true-to-life through the 881S. The 103R rendered them with an euphonious shining "hi-fi personality" which is not on the originals."

The big billowy sound without realism is generally what things sound like in reverse polarity. (Like bass players without fingers, you hear the resonating note but no pluck.) I understand it is a tight squeeze with your arm and cart. You can also change polarity at the speakers and some folks have a polarity switch on their preamp.

In any event, since records are split about 50/50 according to the polarity they were cut with, you will most likely find other records that now sound very good on the 103R but didn't sound as good with the Stanton.

A quick check for correct phasing can be done by placing 2 speakers face to face, with a small gap. If the signal reaching them is in phase, the sound will be strong. If out of phase, they will cancel each other, and almost no sound will be heard. A mono source is recommended.

Cheers,
Alec

Alec,

good of you for this reminder about relative phase. In the matter mentioned by spiralfool it is another issue: absolute polarity.

Both issues are important. I don't know if absolute polarity is audible to me, but may experiment with a cartridge with easier mounting.

Cannot do this with my speakers because mine are "active". Of course, one could go into their innards, or go into complicated connecting procedures to change their phase. But that's quite another story.

Regards, and thanks,

What method did you use to measure the absolute polarity?

Why do you think that absolute polarity is audible?
Technics SL-1200 Mk2 recapped / MN bearing / Funk Firm Platter / Denon 103R / Lundahl LL1681

Hi,

Absolute Polarity brings different points of view. Sufficient to merit a thread of its own, and it is probably the subject of much controversy. I have never experimented with this.

To compare absolute polarity between two cartridges find a record with a very fast, short, sharp transient event on it. Even a permanent loud tick on the record will work fine. Record that passage to your computer. On the same tonearm swap cartridges making sure the wiring is correct. Record the same passage again with the second cart. Then, using any of the wave editors available these days, isolate and zoom way in on that little transient sound in both recordings. If the carts have the same polarity, the two sounds will have the same shape, either a "mountain" or a "valley". However, if one is a mountain and the other is a valley then the carts have different absolute polarity.

As to why I think its audible, I have no idea. BAT, PS Audio, K and K Audio are some of the phono preamps currently available with a polarity switch. In the digital realm my current player has a polarity switch as does my software player, so its pretty common stuff these days. As bauzace50 says, this topic should probably have its own thread. My contribution to this thread was specific to the DL103 which I have found has the opposite absolute polarity from my other carts.

I'm sorry if I missed it elsewhere on this thread, but can you tell me if the standard DL-103 would be nearly indistinguishable from an "R" if both were given the $350 retip treatment by Soundsmith? I have the standard DL-103 and was planning on buying a '103R eventually. But if the Soundsmith mod will make my standard DL-103's performance vault into a much higher league, then I'd go that route. Thanks.

Yes, you missed the point that there's potentially very little left of the original cartridge after mods. So unless the magnet is different, which I doubt, there's not much difference if you're discarding most of it anyway.

But you also miss the point that what you end up with needs to be compared to peers other than the DL-103. So from where you are, what do you want, and what can you get for the equivalent cost of the mod ? Given that you lose the DL-103 in the bargain.

The retip (I have experience with the Expert Stylus sapphire cantilever and Paratrace diamond) is clearly an upgrade and takes the DL-103 well beyond the performance of the stock DL-103R in a few areas. It's quite a lot brighter, though, which may or may not be desired.

The Dl-103 is far from perfect and the Soundsmith mods will in all likelihood fix some of the more obvious failings such as the relatively coarse treble. Also, the mod might result in a lowering of necessary VTF for good tracking. At $350 you end up with quite a bargain, in my view. I doubt there's any competitive cartridge for less than double that.

Hanuman,
your comment on the sappphire cantilever and Paratrace: "It's quite a lot brighter, though..." This disqualifies it for me. I love my DL-103R as it is. No added brightness for me. And the "R" has no treble coarseness.

Having now lived and explored the "R" to my satisfaction, I can live with it as it is, and save good money in the process.

The 103R, with its 6 nines coils is supposed to have a slight edge at the frequency extensions over the stock 103 and with a retip I would expect it to still have the edge. However, I can give you a bit of advice and some opinions based on experience with two 103R's that have been retipped by SS (I've also used ebony, clavellin and aluminum bodies on those 103R's) as well as extensive use with the stock 103R.

There are a couple of things to consider with the SS $350 retip. It has a more extreme stylus profile than Peter's $250 line contact retip so it is much more sensitive to "very" proper setup, including azimuth and VTA/SRA than the $250 line contact which, in turn, is much more sensitive to setup than the stock conical on the Denon. I opted for the $250 retip on both my 103R's as I felt that without on the fly VTA (I have both adjustable azimuth and VTA but not on the fly VTA) I would not be able to take advantage of at least some of what the "optimized contour" line contact that Peter does. If you do not have adjustable azimith, I would definitely do the $250 retip as opposed to the $350 retip and on the fly VTA is probably a very good thing to have if you go the $350 route. I am a set and forget kind of guy so, for me, the less finicky $250 LC made more sense.

System synergy and subjective listening preferences come into play as well. The $350 retip has the potential to offer more in the way of detail retreival (again, if properly set up) but also has a bit more of a reputation for being more analytical and clinical. As such, the $250 retip may be a better choice for you if your system is already a bit lean or you value musicality over the last bit of detail retreival or prefer a less "in your face" kind of presentation. This was another factor in me opting for the $250 retip from Peter.

With respect to the brightness that Hanuman mentioned, Peter Ledermaan has acknowledged a bit of confusion relating to setup remarks on his website. It is implied, as Hanuman suggested, that following the retip VTF may be reduced. This is certainly possible and the line contact will mistrack much more gracefully than the stock conical on the Denons as VTF is reduced. It does, however, start to sound "bright" and a bit odd. For what it's worth, I track both my SS retips at exactly the same VTF that I tracked the stock conical for what I perceive to be best performance and that is 2.6. I've had emails from a number of SS retip of the Denon users hearing this brightness. Almost without fail, when I recommended that they increase VTF to the 2.6 mark (in many cases they were tracking at 2.2 to 2.3 or even less) and focused on proper VTA/SRA as well, they emailed back that this brightness disappeared and the "Denon sound" reappeared. I say that because some posters in these threads imply that the 103 and 103R "disappear" with these mods and that is anything but the case. The mods are about enhancing (not totally changing) the performance of an already very good cartridge and taking it to a very high level without changing the overall character of the cartridge and ending up with something that is far and beyond what you would achieve with the same dollars in a commercial product. I can honestly say that I don't experience any "brightness"; my high frequencies are definitely much more refined and extended with the retip though. I have to agree with Hanuman and disagree with B's post above on treble coarseness with the conical. It is there, without a doubt. The SS retip is substantially more refined, smoother and more natural, whatever you want to call it, in the high frequencies.

One thing I would say is that, IMO, a stock 103 with a retip will be considerably better than a stock 103R that has not been retipped. But, as I've said here earlier, the body is a weak spot as well as the conical and I would definitely recommend doing the body at the same time for the cost involved. Wood bodies are a little pricier, but aluminum bodies are commonly available on E-Bay for $40-$60 and are a bargain. With a steady hand and $60 for an aluminum body (pay somebody who works on cartridges $25 or $30 to do the transplant if you're not confident), $250 for the mid level retip and $75 for Peter to pot the generator (which is what Zu does) you will have a cartridge that, if matched well with an appropriate arm (preferably higher mass) will rival much more expensive cartridges. Art Dudley compared the Zu 103 favorably to $1500 cartridges and that is without a stylus upgrade. Change the stylus and you have much more information retreival as well, taking the cartridge that much further. You can extrapolate that out yourself to estimate what you'd have to spend in an off the shelf product to better it.
