My new Soundsmith Straingauge cartridge

As I've said I'm not an expert to comment on the technical aspects of this discussion.
My q to those who are skeptical of it's approach is what aspects of sound should I be listening for to demonstrate the sound is 'wrong'.
Does this mean that the sound can be 'wrong' but still sound excellent?
My conclusion so far is that the presentation is faster than anything I've heard before, but not at the expense of harmonic development.
However, warm and euphonic it ain't. Maybe this is where it's 'wrong'.

My understanding is that the SG has a very slight deviation from the RIAA curve. IF that is the case, then I would think you would hear a different tonal balance, ie less flat or certain frequencies being slightly more emphasized than others. But Peter L. writes that that has been changed now, so I don't know what you would listen for.

If you like the sound and you compared it directly to other more conventional cartridge designs, then it is clear you made your choice with deliberation and you should continue to enjoy your analog front end.

Perhaps others with this cartridge could also describe how it sounds different from other cartridges.

Spiritofmusic, I have only heard the Straingauge once at a show for a short period. Compared to the Hyperion in the same room the Straingauge's tonality was a little off to my ears. The female vocal did not sound quite right to me. I was listening to a record I brought with me and am very familiar with.

Maybe with more exposure to the Straingauge I would come to a different conclusion.

Sarcher, interestingly, vocals are one area where I feel the SG excels. But ACCURATE tonality on voices, or instruments that's another subject. I guess if it sounds different to a consensus amongst other carts, that could/would be an issue.
Peter, if there is any criticism, it's that the bass is a little different in nature than I'm used too. Initially, I thought it was a little light, lacking in heft, but on deeper analysis, it's just so darn fast. Notes really start and stop, but harmonic weight IS there. It's possible that this is being highlighted by the speed of the tt/arm it's attached too. So the presentation is a little airy as a description, but slam is there, ONLY when it's present in the recording. So many other carts sound over-grounded with bass that leaks into the midrange, dulling the presentation.
But, to be sure, some re education is going on. I'm about to demo NAT 70W/ch SET monos, and this may emphasise a stronger bottom end that could well synergise with the cart nicely (my Hovland Radia power amp has always been a little ethereal at lower freqs).

Spiritofmusic, you should be commended for being open minded about potential flaws of a new thing you are excited about. That's rare.

I would hate to see you get too caught up in watching for what is not right though. It's a delicate balance.....look for what might bug you long term while you have a chance to return, but don't look so hard that it turns you into a maniac looking for flaws! I've struggled with that over the decades in the industry, luckily finding a happy balance where I can focus on deducing flaws but sit back and fall asleep to the music when I want, turning off the analytical side.

Your emphasizing the leanness, pointing out the bass seems lean but then saying it does not when there is impact suggests to me that you are likely onto something, a light presentation in the upper bass through lower midrange, and a slight prominence through the brightness range (1 to 5khz). That's what I've heard from this type cart (while cautioning myself and others that they can't all be called identical!).

If you recognize some deviations (the above described will make it seem there is more detail, which you also have said), so now try to note if that personality is making you avoid some records you really like. Try playing records you like but know are a bit lean. Then decide if the additional leanness causes you to not want to play these records. If so, you may get sick of this cartridge. If no, maybe you can enjoy it for a long time with it enhancing your musical enjoyment. Remember, that is what it is about, reveling in the music. If it, or any component makes you focus more on the component then something is wrong, and over time you'll tire of that. Remember, it's not about impressing yourself and others, unless you've chosen that as your course.
