I’m also using passive preamp and i must say that 5mV cartridge is such a high output already, strange that you’re looking for even higher output cartridge. If your system can’t handle 5mV cartridge i would look for a better phonostage. My passive amp (Pass Aleph) can be switched to the active mode, but i have never ever used active mode even with 0.15mV LOMC cartridges.
Goldring - Audio Note - Roksan ?
I am looking to replace my Grado reference master cartridge that has an output of 5mV
with one with that has a higher output , contrary to the direction of most cartridge makers .
I am using a passive preamp , so maybe I'm being stuborn with my less ( electronics ) is more ,
at the same time I am trying to increase the output voltage of my Tavish Designs Adagio phono amp .
Goldring , Audio Note and Roskan all have an output of 6.5mVs , I've read where the A N is built by Goldring
and it looks like the Roskan is also .
Has anybody had experience , thoughts or opinons with any of these ?
Thanks

Thank You stereo5 I've read some good things about ANs cartridge but there doesn't seem to be a lot of them out there . chakster I don't know what phono stage you are using but it must have one hell of a gain factor. At 1kHz, the gain through the MM input is 44dB, or 158.5 v/v. So, for a 5 mV RMS input at 1kHz, the output would be 0.7925 volts RMS . My amp has a 2.0v sensitivity , so more input would get me closer to it's full output . All in all I would probably be better off adding an active preamp that would give me more cartridge options but I'd think I will try the higher output cartridge first . |
I don’t know what phono stage you are using but it must have one hell of a gain factor. Not at all. You’re talking about MI cartridge with 5mV output, this is high output even for MM. My phono stages are the Gold Note PH-10 and JLTi just to name a few. But i’m using a high efficient speakers (101db) Zu Audio Druid. I prefer passive preams as i don’t need any more gain. With my Grado XTZ ( 1.5mV Output) cartridge the volume control on my preamp is no more than 50% in any situation, normally 30-40%. |
chakstr I have to say Thank You , your answer cause me to ask questions . Do I need an active preamp ? if so why ? So I,ve been researching #s , my amp would like 2 volts imput and I am only giving it .8V with moving up to a higher output cartridge in would be about 1V . On the Thiel speaker forum many owners use CJ equipment , Why ? beacuse they need only 1V input for full output . So now I have a lot to think about ( which means spending $ ) do I look for a different amp and keep the passive preamp or add an active preamp ? Anyway thank you for making me think deeper . Rob |
What is the input impedance of your power amp? Is it more likely it's an impedance matching problem if you're finding a passive resistor pre isn't doing the trick maybe a TVC will (an autoformer type will be more even handed if what Max Townshend told me was true, on the other hand that's the type he sells). |
Thank You yeti42 My amps impedance is 100k ( standard or most common ? ) . I looked up chakstr's phono stage , using rca outputs it's output voltage is fixed at 1V , balanced is 4V ! My phono stage output is only .8V . I've discovered that Goldring makes the AudioNote cartridges and that Decca/London cartridges putout 6.5mVs . Still kicking things around . Rob |
If your amp has an input sensitivity of 2 volts you need a preamp with 2 volts or more to drive the amp to full power. You will never do that with a phono preamp with a .8 volt output. Like I said, you need an active line stage to drive your power amp! Or a phono preamp that has a 2 volt or more output! |
yogiboy Thank you and I agree with you kind of , a new/different amp with 1V input sensitivity would be the direction that I would go , but for now a higher output from the cartridge is the most economical way to go . Interestingly my CD player has about a 2.3V output and yet on the 24 step attenuator with 2db per step the CD is set at 10 and the TT is at 14 during normal listening ! I am very curious to hear what increasing the cartridge voltage output by 20% . Interestly the Goldring 1042 stylus has the same diamond cut as Clearaudio's top of the line MM . |
@chakster I'd like to say Thank you for responding with your experience and opinion . I gained the confidence to purchase a cartridge that I've wanted to try for a long time ( plus one became available at a price I could afford ) a Soundsmith , almost new Carmen mkII , the lastest model with 2.12 mV output . I thought that I would have to turn the attenuator way up but I only went up one or two , from 12 or 13 to 14 or 15 out of 24 . Rob |
