Hegel H160 and JBL 4312E (upgraded version of the 4312)
Would be the HEGEL H160 good match with the JBL 4312E / 93 db (new, upgraded version of the 4312). So far I am using NAD C375 and the sound is good but the NAD has terrible volume gain. On 9 O'clock position is already too loud.
If you are looking for solid state I would suggest a good Marantz product from a good dealer any day over anything from Hegel. The latter may walk away if there are any problems. Not good. Not worth the risk, IMHO.
