Need advice: Hegel V10 phono stage and Sumiko Blue No.2

First, check out the Hegel settings help page here: https://support.hegel.com/product-articles/v10-settings They put it together with tabs specifically to address stuff that wasn’t in the manual, which is a bunch. They get into the settings in more detail.

Second - make sure you’re not confusing 47k Ohm Impedance with 47pf Capacitance. If you’re using the MM setting, you’re already at 47k Ohm Impedance which is what your cart wants.

I’ve got a high output MC cart (Hana SH) with the same output mV as yours and am running the MM setting and inputs, with 10db of gain (44db with my Quattro Fil RCA’s, add 6db for your XLR’s) and have a 2.5mv cart like you have. It’s frigging glorious. I left the Imp and Cap settings as they had them for MM for now but will probably dabble a bit to determine if anything more can be gleaned.

The setup page does imply that MC settings are impactful even when running an MM cart... from there: "NOTE: When using MM cartridges, the MC impedance should be set to 100R to ensure optimal noise rejection. The MM input will always have a 47kOhm standard impedance."

Love the V10 so far and it’s still green - but very impressed with the midrange air and soundstage - love it!

OK, so I had setup this MC cartridge like a MM (plugged in the turntable RCAs to the MM V10 inputs and setup DIP switches as MM). I changed these errors, then used capacitance of 47pf. Sounds MUCH better. @jbfernando how did you set up yours? Thanks!

JB - how did it go? I have been so busy (yes, I know), that I haven't experimented yet on this. Would love to know if you've done this already and have good results. Thanks!

HI Denvercx, Keen to know the final setting you ended up with. Just received Hegel V10 and need to experiment too. Same cartridge - Blue Point 2. Thanks. 

Thanks everyone, this is very helpful. Just learning here, and I appreciate the input! Will make those changes and update the post with the results. 

@yogiboy Gave you the information that you are looking for, all you need to do is change the gain to a higher setting and 47K load. With a moving coil capacitance is a non factor!

In the case of moving-coil cartridges, their coil inductance is so much lower than their moving-magnet counterparts that capacitance will have little effect on the frequency response unless grossly excessive capacitance is added - the circuit would be not so prone to resonance because of the low inductance of the cartridge.

Well, relative to the output of many MM cartridges 2.5mV is not high. Some MM carts will double that voltage, thus providing 6dB more gain. 

What capacitance settings are available? I believe the Blue Point requires a low setting for this.

Yes, I saw that info on the website. I was curious if anyone in here had specific experience in this situation (using a high output MC with MM settings) but which settings? Maybe I'm not explaining myself well. Thanks for your help. 

Here are the specs for the Blue Point. It does not give capacitance specs since that is not a big deal!

Cartridge Type: HO MC
Frequency Response: 15Hz-25KHz
Output Voltage: 2.5mV
Channel Separation: 32db
Channel Balance: 0.5db
Compliance: 15
Stylus Size: 0.3μx0.7μ
Stylus Shape: Elliptical
Load Impedance: 47kΩ
Tracking Force Range: 1.6-2.0 grams
Recommended Force: 1.8 grams
Weight: 6.3 grams

Thanks Yogiboy, that's what I thought, just asking about impedance and capacitance also. 

According to the manual there are 4 gain settings for mm cartridges. Just set to higher gain! BTW, a high output moving coil should be the same settings as a  mm!
