Used Morch DP-6 or modified Origin Live Silver?


Hello vinyl-philes,

Thanks largely to this forum we've shattered the piggy bank and will soon be the recipients of a Teres 265 + Shelter 901. Now I'm stuck for a tonearm. TWL and others warn against unipivots for this cartridge. We understand and agree, so we've come down to the two arms mentioned above. Either one will just about bust the budget, so going up in price is not viable at this time.

Morch DP-6 (used, $800 + phono cable)
- offers adjustable azimuth (does it matter?)
- offers adjustable vertical damping (does it matter?)
- horizontal damping controls stiff cartridges (right?)
- ease of setup? ease of use? reliability?

OL Silver with TWL's mods ($800 + $1.79 fishing weights)
- no adjustable azimuth (does it matter?)
- no adjustable vertical damping (does it matter?)
- TWL's HIFI mod controls stiff cartridges (right?)
- ease of setup? ease of use? reliability?

Has anyone compared the sonics of these two arms with a low compliance cartridge? Your observations would be especially welcome.

Good luck & maybe we can look forward to a review of "my new analogue rig playing Mahler 8". Cheers
Doug, we'll see very soon how my modded Silver measures up with the Encounter. I have an Encounter on the way, for evaluation purposes. Actually, the large bearing housing on the Encounter is partly designed to increase the lateral mass component, and is likely the major factor in the sound difference between the two standard arms. Whether the Encounter's bearing housing matches the HiFi mod in that department is something that we shall see very soon. As far as the hanging counterweight adding to the Silver's abilities compared to the Encounter, I think that the standard counterweight on the Encounter will not match my hanging counterweight on the Silver. All-in-all, I expect my modded Silver to outperform the Encounter. However, I will try my hanging counterweight on the Encounter also, and find out how that combo stacks up in the mix. This should be an interesting week for listening. If my modded Silver beats the Encounter, I'll be gunning for the Illustrious next, to see how they compare. This is really the only way to tell for sure. I'll be doing all my testing with my Shelter 501 on the arms. Of course, I'll give a full report on the outcome.
Tom, I will be interested in the Illustrious/Silver Bullet comparison. Then, maybe someone can send to me a Silver Bullet so that I can do the same comparison! :-)

Why do you feel in advance that the Silver Bullet will outdo the Encounter? No disrespect intended here, just wondering if there is some design that is apparent upon visual impressions only that lead you to this supposition before listening.
Well David, of course it is just conjecture, still to be proven, at this point. But here is my reasoning.

First, the bearings. The bearings are said to be better than the Silver, but since the Silver already has bearings as good as most very high-dollar arms anyway, I really doubt that is going to have an effect. Both arms have their bearings located in the saddle, at wide spacing, similarly. So, I estimate the bearings to be a tie, in real-world effect. I could be wrong, and there might be a slight edge to the Encounter here, but only as much as you could hear the difference between ABEC 4 and ABEC 5 bearings. Not much.

Next, the arm tube. The Encounter has a different tapered tube which may actually be better than the Silver's tube, as far as resonance control. I don't think the stiffness differences of the tapered tube will be a factor. So, the Encounter may have a slight edge in arm tube resonance, but we'll have to see if that is the case or if it makes an audible difference. Possible edge for the Encounter here.

The end-stubs are the same on both arms.

The major factor that I see in the improved design of the Encounter is the massive bearing housing. While this looks like it will provide a "very strong" support for the arm bearings, in fact that area doesn't really need to be all that strong. It is plenty strong enough in the Silver to withstand any possible deformation of the bearing saddles, at the forces that are present there. But, it does provide a certain amount of added lateral mass, which provides an increase in performance that is aimed at doing the same thing as my HiFi mod. Here, the question arises, does it do the lateral mass thing as well as the HiFi mod? This is what I want to see. Frankly, I don't think it will do as well, because the mass increase on the Encounter is located almost entirely within or around the perimeter of the bearing saddles. It does not extend outward beyond the bearings to any extent at all. I'm not sure of the material they used yet, but it is likely to be aluminum from the looks of it. So the Encounter's lateral mass increase is a lighter material and not placed as wide as the HiFi mod. There may be some more material there, but it would have to be alot to overcome the difference between lead and aluminum. Also the positioning is very important, because the force is increased by "mass times distance squared" calculation. So the higher mass, and the distance from the center pivot, are key factors. My mass increase is much wider and therefore exerting much higher static moment in the lateral plane, than the Encounter is. The result of this, is that my modded arm has the ability to stabilize a higher force of stylus excursion, before being moved laterally in an unwanted fashion. Since I already have tested and used my mod, I am certain that this level of static moment in the lateral plane is not causing any problems to the normal movement of the arm. So as long as the mod doesn't impede anything, it is not too much force. Also, since my weights are attached to the actual ends of the bearing axle, they provide mass and damping to the axle itself, and make it nearly impossible for tha bearing axle to be excited by any arm vibration, which could cause bearing chatter. Chatter is virtually eliminated with this mod entirely. The Encounter(nor Illustrious) have this characteristic, and rely solely on the bearing adjustment for chatter control, and are not subject to the benefits of the advantages that are present in my HiFi mod in this regard.
Possible large edge for the Modded Silver here.

Counterweight. The counterweight on the Encounter is the same as on the standard Silver arm. This has been tested by me, as I mentioned earlier. The standard counterweight is easily bettered by the Heavyweight, which in turn is easily bettered by my hanging counterweight. No contest here. Definite edge for the modded Silver.

Wiring, from what I can tell, is the same on both arms. Adequate, but nothing exotic. This should be a tie.

Baseplate and mounting. The Silver has the Rega baseplate, and the Encounter has the new OL Baseplate. I like the looks of the new OL baseplate better, but I don't know whether it sounds any better or not. This is an unknown.

To sum up, in my opinion, the main reason why the Encounter is considered an improvement over the standard Silver arm is the increase in lateral mass provided by the large bearing housing on the Encounter. Users and reviewers of the Encounter are hearing the benefits of what I've been saying for over a year now. They've never heard or used my HiFi mod, so they are extolling the virtues of the "more controlled, better bass, dynamics,detail, and tonality," sound of the Encounter, without actually realizing what is causing the improvements they are hearing. I do realize what is causing the improvements. So since I think this is the case, and from my estimation and calculations my modded Silver has a better designed lateral mass implementation with greater control, I predict that my modded Silver will have a greater improvment in this area. Additionally, my hanging counterweight will be a definite improvement over the standard one on the Encounter. My guess is that these 2 major factors will exceed any of the benefits that may be normally afforded to the Encounter, when both arms are in their standard configurations.

I think that most of this also will apply to the comparison with the Illustrious, although the Illustrious has better wiring, and that could complicate matters. But the basic design of the Encounter and the Illustrious is extremely similar, and if I can beat the Encounter like I think I can, I'll have a real shot at the Illustrious.

So, those are my pre-judgments on this matchup. We'll see soon how accurate these thoughts are.

By the way, I like your "Silver Bullet" moniker for my modded Silver tonearm. The name fits well, in several respects.
Very interesting. Let me ask a few questions further, if you will.

By all accounts, the heavier counterweight on the OL Silver and other Rega-based arms is accepted as a worthwhile mod. So much so that one sees, "worth its weight in gold" and other such comments in testimonials. Given such wide acclaim, why, in your opinion, did OL not incorporate this feature or something similar into the design of the Encounter and Illustrious? For the price, these arms SHOULD be more than a degree or two better that the Silver. Would seem to have been a no-brainer based on the sales records of that mod alone. Suppose it is a blind adherence to one's own design? Wouldn't be the first time that has happened!

If, in your estimation after comparing, the Encounter outperforms the Silver, what then? Of course, it would depend on the degree. Just a wee better would give the nod to the Silver as having more value. But, if it is more than that, do you try to tweak the tweaks for the Silver to make it match, apply tweaks to the Encounter to make IT even better, or both? :-)

There are not a lot of independent reviews to be found on the Encounter and Illustrious at this point. One of the most glowing reviews was done by Stereo Times and Hi-Fi News . Some have criticized the reviewers as "being in bed with OL", but I haven't a clue. Anyway, even these thumbs up reviews cite play in the bearings with the arms, same as noticed in the Silver. I know there is a trade of between fluidity and stiffness with a gimbal arm but play seems unacceptable. Does your HiFi mod, in part, address this "looseness" in any manner. If so, would not the same type of mod prove beneficial to the more expensive, "better" arms. I guess I am wondering if there is possibly more hype than design in these arms.

With respect to the Encounter/Illustrious comparison. A visual inspection reveals that they are very similar, indeed. A different plate used as a arm pillar/tonearm rest support, one silver the other black, "gold" accents on the Illustrious. You mention that the Illustrious has upgraded wiring. The website for OL claims not cost pared in materials for the arm tube and bearing with respect to the Illustrious. Yet, they look the basically the same. Since it is somewhat hard to find information on these arms, other then the OL site itself, do you have the skinny on these two? Are the arms tubes, bearings of a different composition, etc.? I have asked these questions of some internet dealers and found the responses somewhat vague.

Oh, one more thing, and anyone please jump in here. OL arms up to the Silver have been seen as a true VALUE in the sense of performance/cost ratio. If the law of diminishing returns has set in with the Encounter and Illustrious, does this mark a change in philiospohy of OL to focus more on profit, or is it more likely a failed attempt to improve design? I am not saying this is the case, but if Tom's suppositions prove true, it would call into question the value statement.
