Is this why my analog rig isn't so hot?


Hi All,

My system is quite decent, but...

Could it be the voltage output of my Benz Glider is too high?

My photo stage - a 47 Lab PhonoCube - could handle low outputs down to 0.12 mV. Since my Glider has a medium output (0.83 mV) - is this why I'm not that happy with my system? I seem to want to hear more, specially the top.

If I got the same Glider but with a lower output, would it make a difference? Or should I get a better cartridge? And which one?

My system:

Basis 2000 table
RS-A1 Lab arm
Benz Glider (0.83 mV)
47 Lab PhonoCube phono stage
47 Lab Chooser passive preamp
47 Lab Gaincard amp
Konus Audio Essence speakers

Thanks!
George

Hi NGeorge,

(Yes, I hang out here too!)

I agree with all the above, although certain cartridges mentioned by Pcosta are probably unsuitable for your arm. I also like the sound of the Denon 103's, Shelters(!) and Koetsus. But I'd never put one on an RS-A1. (Remember the "moving mass" issue we discussed?)

Lyra (also recommended by someone on VA) and Dynavector are both likely to be more suitable compliance matches for an undamped, unstabilized unipivot. Even the damped and stabilized Graham 2.2 cannot get the most out of low compliance cartridges like a Shelter or Denon.
Paul, Sean, Asonicyouth, Doug,

Thanks for your input. I'll be on the lookout for those cartridges.

Best,
George
I have the Benz Glider v2 Medium output. I do notice that the cart likes to be demagnetized before sounding its best.

I have your cartridge - loading it correctly is everything. If your phono pre allows for adjusting of the load I suggest that, if you haven't already done so, that you expiriment with different loads. You might do a bit of research on this issue on this site and on Audio Asylum's. I recall participating in such a thread a couple of years back. The preferred loading range varied between 2000 and 22000. I run mine at 10K and it sounds just fine, I'd probably fine tune it further if I could just switch out resistors in my amp 'til I got it perfect. At 100 ohms its just plain dull and at 47K its a bit bright and thin. Can't imagine it at less than 100 ohms.
Dear George: If you have the standard version of the Phono cube then it will be better the low output version of your Glider cartridge, this one has an internal impedance of 13 ohms. Other alternative is to change the Phono cube version for the high gain model.
The problem in the high frecuency reproduction is not a cartridge problem: it is a 47 labs system problem, you can read severals reviews about it.
I agree with what Sean told you about a proper installation: tonearm/ loading impedance/VTA-SRA.
You don't need to change your tonearm it is ok ( I own one of this tonearm ) and works best than SME with the Benz cartridges.
Btw, Doug, Paul and Sean: I own the Ruby 2 and the LP Benz cartridges and I never experienced that lost in the top end, I think that the people that has that problem is because a mismatching analog system and not because the Benz Micro cartridges. I think that the people that has that problem are using tube electronics.
George don't go with the " Denon 103 myth ", this cartridge
was an " ok cartridge " more than 20 years ago, but by any music reproduction standards it is a bad music reproduction transducer, it never was and state of the art cartridge by any standards and it never will.
Doug: the Graham tonearm has many problems, specially with low compliance cartridges, not because is a unipivot tonearm but because is a bad design.
Regards and always enjoy the music.
Raul.
