I hooked it up on my epa 250 arm and it seems to me a little splashy, i have it loaded it with 400pf over and above the cable and stuff, i am using a John Rich cable with a claimed 16 pf/ft capacitance, so let say the 3 foot cable plus the arm which has cardas wire inside...i would guess the total load is around 450 to 500 pf. This is the max i can add without going to external caps. what is the general experience with the V15 type 4 as far the optimal capacitive load?

I'll play more with it. It sounds fine just nothing to grab you. You almost get pulled into it, but then you don't. I have it because it came with a table i bought, and then i bought the Jico for it...things improved quite a bit with that. On the plus side this is the one cartridge i own that mates best with the technics EPA 250 arm so far...strange, i thought it would be too compliant for the technics.
Some people rave about the V 15, so i just wanted to figure out what was the cause of the lovefest, still on the quest but loosing faith in finding the reason :). With the Decca the understanding was instantaneous, as soon the stylus hit the vinyl, you knew what was the reason for the animal attraction, like a 60s Britt sports car, ugly flawed ruckus precarious ride, but the feeling you get, makes you 17 again. A shitty grin from start to finish. The Sure is like an E class Benz, nothing bad just sad and boring.
oh well,
keep looking.

I found 100 pF on the phono preamp and low capacitance ICs to sound best.
Opus 33 1/3
I like mine (with an MR stylus) around 150pf. Although you you'd have more output above 10,000hz, you'd have a little less between 5,000 and 10,00hz. That may actually sound less splashy. Worth a shot.
with no extra caps, most likely between 50 to 100 pf, then added 100, 200, 300 and finally 400 pF. the 400pF sounds the most balanced but has less top end for sure...the others have more on the top, but the midrange is less full. the 300 pF setting may be optimal for bandwidth, but sounds still a bit unbalanced to my ears.
The other HO cartridge i use the London Gold reacts very differently to capacitive loading, and sounds best with as little as possible. Neither are as good as the MCs i use, but neither of the MCs really like this arm...that is another problem...so it is a bunch of compromises :)...oh well.

G'day all, which Shure V15 model is it? The earlier V15III like pretty well all Shure's of the times 'liked' 47 k plus 400 to 500 picofarads (overall from all sources).
The latter V15 's (V15IV? and onwards sounded best at 47 k and 200 to 300 picofarads, with around 250 picofarads being preferable and again this is an 'overall' value, including tonearm wiring, interconnect and phono stage input capacitance.
Being all high inductance phono cartridges optimum capacitance loading is important with all models of the Shure V15 series. Get yourselves a good capacitance meter and start measuring! Regards, Felix.
I guess it will depend somewhat on the paired stylus - with a JICO SAS on my V15V, my white noise measurements showed that that the V15V output was insensitive to changes in C up to ~250pF total load. I settled on 150pF as my preferred load with a standard 47k load.
FWIW, the V15V with JICO SAS is (at present) my favourite high impedance MM with a tonal quality that is very close to my Denon DL301/II. Bags of detail combined with a wide and deep soundstage with an unfatiguing sound that is neither bright nor dull and silky smooth..... like a good Scotch!

with Jico Sas...not bad...but not an exciting sound, nowhere near as exciting as the London....but then again there is not much as exciting as the London, but then again the London is quite colored....and looses composure easily...the Shure never does that.
When it comes to detail and refinement they both loose out to the Win SMC10 by a wide margin, but the SMC10 is on the border of tolerable resonant frequency with the epa250...bummer, it could be extremely good if it did not go into warble mode at times on warped records.....oh well maybe the next arm.

G'day mate, all ok then. As the Jico SAS stylus has a slightly 'peaked' treble response the optimum capacitance loading is probably slightly less for the flattest and most linear overall frequency response.As some of you will know I have done a lot of testing with the Shure M97xE with both load resistance and load capacitance. In the end I have settled on 47 k and 270 picofarads for the most pleasing and 'musical' sound, with the supplied Shure elliptical stylus. Regards, Felix.

hi felix,
i've been thinking about you and that you don't post at karma anymore. glad too see you here.
i have a v15Vxmr that, like most other shures, i couldn't warm up to its sound. i prefer low output MC carts and that was just made clear again when i went from my grace f9e to my AT150/170ML to my fidelity research FR1mk3. ahhh, home again.
now that i have a rogue triton phono preamp with adjustable capacitance and impedance, i can try the shure with other capacitance settings to see if things improve sonically.
...regards...tr
G'day mate, nice to hear from you again. Alas I'm not welcome at Karma anymore. It's a long sad story I'm afraid. All I'll say it's a bit of a 'moderator' issue!
Interesting on the Shure's too. Well on the V15VXmr, the last of the series was supposed to have the 'warm' Audiophile Response curve with the slightly rolled off upper treble.
Again the optimum capacitance loading is important (47 k and 250 picofarads). I did have a V15III and thought it was way too cold sounding and bright, and it needed a lot of load capacitance (around 500 picofarads) to 'tame' it down. Regards, Felix.
i was once ejected from the karma by Grumpy for a conflict, with him i believe where he did what he accused me of. at any rate, i made a public apology there to the general population so i could continue there.
you may or may not agree that there is some good entertainment there.
now back to the topic. after i experiment with the capacitance of the connection of the shure to my system, which may be a while due to my happiness with MCs right now.
looking forward to your input when i do AND to the actual results.
...regards...tr
I also did this with a Shure V15V15xMR and used it to get a flatter response. You should be adjusting both the resistance and the capacitance together to get the smoothest response. It is one of the damnable things about MM.
I do not have adjustability of the load resistance....but i will consider playing with this in the future. It is a bit strange that what i am hearing is not exactly what the measurements would indicate. Maybe moving the resonant peak down toward 12 to 13 khz actually improves the upper midrange at the expense of top extension is more pleasing. I can tell for sure that 47K and about 250 pF just did not sound right.
