Pushed out by a 0.2 MC cart ?


Dear all after changing the speakers it seems I can now see the other components limitations in my system. Specifically due to the lower speaker sensibility I have to increase the pre volume increasing substantially the background hum of the MC cart. Before it was not relevent while now it0s bit too much. This is my system now:
Denon D 103 + Sme 309 + Coph Nia phono stage + Goldmund pre/power amp + Burmester 995 (previously a 2dB higher sensivity speaker)

On top of this, as an additional information, the TT has lost some magic and it has still retained it with audiophile quality vinyl only,more silent and dynamic.
But with majority of lp's the sound has been outclassed by the CD player (a CEC)
Now:
Would you upgrade the cart to a higher output cart ?
Would you play with the impedance matching ?
Would you upgrade the whole TT ?

Tks so much for helping me

Ad there used to be passive step-ups available -- I have a pair from Sony, they're simple rca jacks. At least, you'll know that it's the transformer you need -- NOT a new set-up. BTW, I fourth the recommendations above.
Also BTW, I used to have a PT Too / Alphason 100. Pretty good combo!
