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:

Raul,
You are right about trying to minimize the factors between tonearms. However, I agree with Paul about the important fact that using a wire that is not offered to customers would be a serious problem in any type of evaluation. Nobody would know what the "real" tonearm would sound like.
I don't think Frank and I use the same type of cable.
Another aspect of this is that, to a certain extent, the tonearm is "tuned" with the cable I'm using. If I used another wire, I might have to modify other things to get to the sound I want. In that sense, the cable is as important in the global sound result as, say, the wood I use for the armwand, or the material I use for the counterweights, and so on. Any change anywhere modifies the delicate balance between the elements. It can bring the whole thing to a higher level, of course--I'm not implying that I currently have the perfect recipe--and when that is the case, I adopt the change.

IME you can have 2 identical cartridges in 2 identical tonearms with all parameters being the same. The chance of the sound being the same is very slight. Depending on the break in period, amount of warm up etc the exact same cartridge will sound slightly different.
Dear Joel: Yes I understand what you mean and about the tonearm voicing.
I along my friend Guillermo are for the last three years in a self tonearm " universal " design an think I understand every single " subject " about.

Anyway I don't want to go " inside " no more in your tonearm design or Frank's one. We can agree overall but I know each one of us have some very particular " ideas ".

Regards and enjoy the music,
Raul.
Petng,
I too would love to know more about the Kuzma top pivoted tonearms and how it fits in with Triplanar, Graham, Talea, Schroeder, Reed, SME. I can't even find a good photo of either. The 4-point is the top of the pivoted line, is it not?

Here is a Kuzma 4point review in PDF from Hi-Fi Plus. Excellent pictures. It's an ingenious design with with 2 points for the vertical bearing, another 2 points for horizontal bearing. Fluid damping for both directions. Extremely small contact area (like a unipivot) and very stable (unlike a unipivot) and long armtube (smaller tracking error) with standard mounting distance (easy installation). And pivot point at record level (good for warped records). Pretty neat, I say!

Never heard the sound but would love to hear it.
