Schroeder Reference Arm


Hi Folks:

The great Peter Lederman of Soundsmith uses this arm on his VPI HRX Turntable.

What was surprising about Peter's rig is that as much as I respect and like the HRX, I always find it's sound slightly clinical; however the addition of the Schroeder arm made the table sound slightly richer and less clinical while blowing my mind with it's dynamics and accuracy. Has anyone else noticed or tried this? I am experienced enough in this hobby to understand that the tonearm and cartridge provide voicing for the system but a tonearm swap on a turntable of this quality surprised me with the overall change it made. It goes without saying that I think the JMW tonearm series made by VPI are excellent.

Best:

Is the Talea still a state secret? Its existence has been publicly disclosed. We know who you lucky owners are, so 'fess up.

Doug, I would be interested to know which of the more popular cartridges put a lot of energy into the tonearm and which ones don't, in your experience. I think you may have come upon a useful way to predict felicitous tonearm/cartridge matches, apart from the well known ones related to effective mass of the tonearm and compliance of the cartridge.
I have had the Schroeder Reference the last 5-6 years using it with my ZXY Universe. It is an excellent arm and I am not surprised by the results that you heard with the HRX table. I have though recently switched to the new Talea arm (number 008). As in previous comments it is more dynamic and accurate providing more detail but in a very natural way. The ease of adjustments with the Talea is without equal in my experience as you can do both VTA and azimuth adjustments by ear while playing a record. Both tonearms are really good but in my system with my preferences the Talea outperforms the Schroeder.
Im curious how one determines that energy is leaking into the tonearm and how resonance in a tonearm is measured or quantified. Any clarification on this would be greatly appreciated.
Dear Rccc, I too asked Doug about his ideas on cartridges that put a lot of energy into the tonearm, and cartridges that don't. It makes a lot of sense that cartridges could differ in this way, due to the huge differences in construction of one vs another. But I would like to know what Doug knows about specific cartridges.

As to the second part of your question, that is not so hypothetical. The tonearm+cartridge is treated as a single entity, and the resonant frequency can be both estimated and accurately determined by a variety of methods. John Ellison over on VA invented a neat way to determine the actual resonant frequency of the tonearm+cartridge, by simply dropping the needle onto a disc whilst recording the sine wave that is thus generated using a computer program. By observing and measuring the decay of the sine wave, one can calculate resonance. I can't recall further details, but it is a very clever idea. You can probably find it on VA by doing a search.
