mismatch between the phono stage and preamp?
the input impedance of the preamp is 10 k ohm
output impedance of the phono stage is 50 ohm
the cartridge is 0.2mv
the sound is little dead,can be better bass,focus....
the phono stage is setting to 70db (max)
thanks

Re: mismatch between the phono stage and preamp?
John - Given those specs there's no obvious mismatch between the phono stage and preamp. There are so many variables in a phono rig, I'd suggest checking and tweaking the cartridge alignment, VTF, VTA, etc.

Re: mismatch between the phono stage and preamp?
How about listing the brand and model number of the preamp and phono stage you are using?

Re: mismatch between the phono stage and preamp?
phonopre impedance to pre look fine to me. what about cardridge and phonopre?
can it be that you are using the standard 47k impedance setting at the phonostage? low output mc cardridges tend to have low internal impedance.
the input impedance setting of the phonostage should be about 10-20 times the inner impedance of the cardridge.
f.e. quintet black - internal impedance 5 ohm -> phonostage about 50-100 ohm.
"dead sound" normally occurs with the mc phonostage is set to 47k.hifi:
power: Audioplan Powerstar, Audioplan Finefilter, Audioplan Powerplant, Powercord
tube amp: Jadis DA 50 Signature RC, Line Magnetic 508ia
speaker: Living Voice Avatar 2
turntable: Pro-Ject Xtension 10 + Ortofon Quintet Black MC
phono stage: Remton 383 MKII
cables: Audioplan Musicable bic 7a, Profigold, Wilbrand
home-cinema: Sony blu-ray, Yamaha rx v2700, Heco Metas 700 (4x), Heco center
