Would Like To Hear From Strain Gauge Owners

Dear MrjstarK: I'm not saying that sounds bad or not to buy it I'm only point out one of its characteristics, that's all.

Regards and enjoy the music.

This is the one time that I hope that my response is deleted by the Agon censors. Simply because I think Mrjstark's post is an absolutely perfect way to end this thread.

Dan-ed, As an engineer, you know far better than I what's going on, but as I understand it, the job of the RIAA equalization network is to UN-"squash" that which was squashed during the conversion of the musical signal into grooves on an LP. So, the squashing has been done a priori. Then, if the RIAA equalization is not up to snuff, there may remain some squashed frequencies and/or artificially enhanced frequencies during playback. That's not a good thing, either. I hear the negative effects when I play some early 50s mono LPs that were not cut to the RIAA curve. (Try listening to the original recordings of Ella and Louis, for example.) I say this as someone who is not as anal as Raul about RIAA but who is trying to see his point. I am completely open-minded as regards the SG cartridge, however. Sorry to add one more post, Frogman.

The Ortofon range of cartridges give distortion specs for their 20Hz-20Khz response (in addition to a frequency range spec).Some of them far greater distortion i.e 0-2.5dB than the relative distortion might be for the Strain Gauge limited to just this spec and not 12Hz-50Khz given.The cartridge distortion is what is important and even a fine phono stage will not hide this.Please correct me if this doesn't make sense.

Hi Lewm,

Again, I don't build phonostage or preamps so I don't claim to be an expert on RIAA. There are many others who have posted on this issue on this thread and other threads, like the one I linked before, that are far more qualified to speak on the subject than I am.

As I understand it, the issue is not if RIAA correction should be done because it should. The question is during reproduction how faithful to the curve does this correction need to be to sound good? Some phonostage and preamp designers argue for strict adherence. Many more argue that the extra components need to conform to strict adherence add more bad things than they help. I think anyone who has experienced changes do to cap and resistor swapping can appreciate this concept.

IMO, Raul has always argued for strict adherence to the mathematical models that define the RIAA curve. Ok, that's his opinion and he's entitled to it. But I have never heard any other phonostage/preamp designer insist on this rigorous interpretation. Raul and Jose have built a very fine product. However, there are other products out there that do compete very well against their box. So why doesn't one sound clearly superior to another? I don't know, but this .1 dB adherence does/did not translate into any sonic revelations when I heard it. Unless something else in the implementation is holding it back.

As to the Soundsmith SG, it seems to me that Peter has posted that the SG does do RIAA correction. Perhaps, and this is my interpretation of what I'm reading here, not in the more conventional way because of the natural response of the cartridge used which is also not your conventional cartridge.

In the end it all comes down to how does one wish to select a product. By arguing numbers? Or by listening?
