Low volume with phono stage and hegel 190


Just bought a hegel 190 driving my b&w 804s.
Plugged in my rega fono3 phono stage .
Dropped on a album to listen to and wow really low volume even with amp turned to max.
Cartridge is a dyavector 10x5.
Measured the dB at max and came with 84db at 1m.
Plugged my musical fidelity a1001 amp back in got the same dB for 40% of the volume using the same phono stage.
Could turn the A1001 amp up to way past party levels before the woofers bottomed out on the suspension. And the volume was at only 70% 
The hegel is rated at 150 Watts rms class a b and my A1001 is rated at 200watts rms class a b.
Anyone else had issue's with anologue inputs with the hegel 190? Any advice on a higher output than the fono3 which I think is 41.3 dB of gain.

Ever hear that cartridge output varies?
By a lot more than most phono pre’s.
The Rega is stuck @ 41 dB gain and you need 45.
The Hegel is not your problem.
Thanks for all your replies .
I agree it's the rega fonos problem being a low gain.
So this afternoon I bought a Trichord Delphini mk2 MC/MM phono stage today off ebay which has adjustable gain for mm up to 52db and  for £380 it was good value .  I was about to order a Dynavector p45 mk4 when I saw the trichord.
