I'm a new owner of a Technics sl 7, it was a local deal so I had the chance to listen a demo and it sounded good, loud enough with an old amplifier... When I got home and connected to the phono of the Yamaha r-n500, I couldn't hear a thing... I had to put the volume to maximum to hear something... The groundwire of the turntable is connected to the chassis of the amplifier. The amplifier drives a pair of Dynaudio DM 2/7. I read that Yamaha has an MM preamp, the cartridge on the turntable is a technics p22.
I believe is a mismatch of the technical characteristics, I have here the details, maybe the info is there but I don't have the knowledge to find it so maybe someone can help me, please:
Technics EPC P22

1.0 - 1.5g Mass
6g
Channel Separation
22dB Channel Balance
Load Impedance
47k ohms Output Impedance
Stylus
EPS-22ES Stylus Tip
elliptical 0.3 x 0.7mil Cantilever
pure boron pipe Dynamic Compliance
12 x 10-6cm/Dyne Static Compliance
Notes
P Mount
Yamaha r-n 500
Phono MM : 3.5 mV / 47 k-ohms
Réponse en fréquence : CD,etc. (20 Hz–20 kHz / 10 Hz–100 kHz) 0 ± 0.5 dB / 0 ± 1.0 dB
Distorsion harmonique totale (20 Hz–20 kHz) :
- CD, etc. vers Speaker Out : 0,015% (40 W / 8 ohms)
- Phono MM vers Rec Out : 0,025% (3 V)
Ratio Signal/Bruit :
- CD, etc. (200 mV, Entrée Contournée) : 100 dB
- (Réseau IHF-A Network) Phono MM (5 mV, Entrée Contournée) : 87 dB
Amplification
Puissance maximale (4 ohms, 1 kHz, 0,7 % THD) : 105 W + 105 W
Puissance nominale (8 ohms, 20 Hz—20 kHz, 0.04% THD) : 80 W + 80 W
Puissance maximale (JEITA) (8 ohms, 1 kHz, 10% THD) : 115 W + 115 W
Puissance dynamique/cn. (8/6/4/2 ohms) : 105 W/125 W/150 W/178 W
The old owner kept saying that I need an analog amplifier.
Changing the cartridge would help?
