Question about my phono stage

Post by Frankie Lee »

Just wondering if my amp's phono stage is capable of running a Moving Coil cartridge. It's a MM stage, but I believe that some of the Denon MC's are high-output. I have no idea what specs are important, so here are the ones I thought looked appropriate.

Here are the specs of the amp's input:
Input Sensitivity/Impedance (100W/8Ω)
Phono MM: 2.5mV/4747 kΩ

Maximum Input Signal (1 kHz, 0.05% THD, Effect On)
Phono MM: 130 mV

Here are the spec's for the cartridges I was thinking of getting:
Denon DL-103
Frequency response (Hz): 20-45,000
Output@1khz, 50mm/sec: .3mV
Output impedance: 40 ohms
Load impedance: 100ohms

Denon DL-103R
Output: 0.25 mV
Output impedance: 14ohms

It won't do for a 103 - thats a low output moving coil. It will work though for the likes of a DL110 or 160, sumiko blue point special and pretty much any moving magnet cartridge
Do or do not, there is no try

Hi Frankie,

The Denon (or any other low output mc cartridge) will work if you use a step up transformer. You simply insert it between your turntable and amp. I have a Rothwell MCL for sale... see below. Your welcome to try it if you wish.

Hope this helps.

Thanks for that Terry. Might well be interested alright. Have PMed

This takes me to another point, which upgrade path do I consider? New cartridge or phono stage?

At the moment I'm running a Rega Elys on a Rega Planar 3 through a Yamaha DSP-A1. I'm happy with the balance of the sound but would like a bit more detail and to soften the top end a bit. My difficulty is I can't really ascertain how good the Yamaha's phono stage is. It's an old amp and there's no real reviews about the phono stage to give me any idea. I know most AV amps have crap phono stages but this was once Yamaha's flag ship processor costing E3,000 so it can't be that bad surely?

Perhaps trying a decent phono stage would be the first step.

Frankie. Have a read of the following... http://www.audioasylum.com/reviews/Phon ... 64265.html

It uses your amp, a step up transformer and a Audio Technica 0C9 moving coil cartridge. I use the MKIII version of this cartridge and it works very well.
