24.128.104.213
on an old shure V15Vx. Out of the box the bass is much deeper than other cartridges I have been using and the lower midrange is strong but the treble seems less prominent. Is this a feature that changes with the cartridge breaking in, or is this typical of a cartridge that isn't properly set up. I was pretty careful and think I did the same job I generally do with all the other headshell and cartridges I use. This is on a technics sl1200 mkII. The new stylus tracks like a son of a gun and is incredibly quiet and there is a lot of detail. I don't know if what I am hearing is a truer representation of what is supposed to be in the grooves or if the other cartridges were "truer" to the original sound. Any general recommendations. Thanks Norm

I think my V15Vx/SAS sounds better and tracks as well with zero anti-skate. Others have had the same experience. I haven't noticed a difference in the bass but it's worth a try.
I have found best results with my yamaha yp d71 and v15x+sas combo at 1.65-1.70, brush down, and zero AS. Good to hear you guys are also confirming best results on zero AS

Hopefully growing!
In my system the V15Vx goes deeper than most other cartridges, with both the original and SAS styli. The bass I hear, however, is clean and does not seem excessively full. For reference, I have an NHT 1259 subwoofer that goes all the way down. I formerly played the double bass.
I sometimes hear distracting low frequency artifacts, such as a foot tapping near a mic stand, and once what I think was the rumble of the R Train near Carnegie Hall. A few LPs seem to have excessive very low frequency boost but most seem reasonably balanced to me.
If the bass is too full you may have a loading issue, but I would try a few things first that are more easily dealt with.
I would check the VTA and VTF. I would also try moving your speakers. If you have located them based on other cartridges, a little relocation may bring them in balance with the V15Vx/SAS.
This sounds typical of many cartridges during 'break-in'.
If you have less than 20 hours on this one.......I would keep playing it before panicking.
The changes can be quite gradual on some cartridges yet on others.......can suddenly come 'on song' after 50 hours.
Are you running with the Jico brush down? I was wondering if VTF is set correctly. Too much VTF also alters VTA. I don't know how the original Shure brush worked (for VTF compensation) but with the Jico you add 0.25g - so 1.5g VTF with the brush down. Or maybe just run it without the brush at the recommended 1.25g?
Per Jico's instruction I am running between 1.25-1.5 gm. I did the VTF with the brush up at 1.8-1.9 gm and subtract the 0.5 to account for when the brush is down. I will check the measurements carefully and over the next week fiddle with the arm height. Previous posts have suggested the ideal SRA, but my eyes just aren't up to that degree of accuracy. If things change over the next 1-2 weeks I will update my findings. Norm
"Per Jico's instruction I am running between 1.25-1.5 gm. I did the VTF with the brush up at 1.8-1.9 gm and subtract the 0.5 to account for when the brush is down"
It is my understanding that the Jico brush only substracts 0.25g? So not the same 0.5g as the original Shure brush.. So either you run with the brush up at 1.25g or with the brush down at 1.5g.
Right now it seems that you are effectively running at 1.55-1.65g (1.8-1.9 minus 0.25). That could explain the sound you are hearing as VTA will be changed quite a bit from the added VTF.
Have you tried 1.25g with the brush up just to confirm?
as per the shure instructions. I will change the settings. Thank you. Norm
You're welcome. Still - I would confirm by trying 1.25g without the brush. For the sake of comparison.
Also, I agree with Briggs about using very little anti-skate with the SAS stylus - its friction is very low so little needed (see link).
Been enjoying the Jico SAS MM-1 myself.
If phono cable is greater than 250 pf. In my experience (V15VxMR) too much cable capacitance on this cart will result in rolled-off high frequencies.But then if you are hearing a familiar cartridge but just breaking in a new stylus assembly, it may be that the suspension in the Jico stylus assy needs to limber up a bit...and as the thing continues to break in, sonic character will change.
As Jrags suggests, a different stylus profile may require a different vta adjustment. VTA will have considerable effect on the overall tone character of the cartridge.

Since this stylus is similar though not exactly the same as a microline/microridge stylus, the setup is still critical. I would play with VTA from the horizontal position as a start. Go up two playing cards at first, then have fun from there. If you find a sweet spot, then you may have to adjust azimuth.I really believe you need to experiment with VTA, given the stylus design.

It would be interesting to look at the frequency response curve. Here is one I measured several years ago on my Shure V15VxMR, which I purchased brand new just before they were discontinued. I was never very impressed with the sound of this cartridge, but I'm also a moving coil lover.
For anyone expecting the "classic" V15-III sound, the V15V is not going to help you reminisce. Perhaps, shorter tt cables might help a bit; but I doubt it. There are better and cheaper carts to groove with...
