Sloppy, muted bass response on Hegel h190


 Hi, I have a Hegel h190 integrated, a pair of Kef  104/2's from 1985 that have been rebuilt but I don't know whem, the speakers have new donuts and new silver Kef tweeter.  I mostly use the sonus connect.   Also I have a 15-year-old Sony sacd disc player. I'm getting low, sloppy bass when I play either cd or wifi.  This is the second amp.  The first one exhibited same issue.  Same amps.  New.

I only have one set of speakers.  I am thinking perhaps a capacitor in Kefs?  This amp should have solid punchy bass, but it is not there.  Speaker cables are blue jean 10 ga banana plugs.  IC are blue jean also.  I am at a loss. I heard the demo Hegel played on these components and it was fabulous.

any thoughts?  I hate to sell everything and start over, but I am at that point.
thank you

The speaker placement is measured and exact.  The speaker cables are correct and tested.  

 




I listen to my Hegel H90 thru my Sonos Connect (old Z90 model I believe) into my 30 year old Cornwall ii’s. My sources are vinyl and Spotify. Sounds so sweet to my ears. 
I knew the Hegel was manufactured in China before I purchased, could care less... great company and awesome amps. 

I've tried the Hegel H190 on the KEF LS50, Reference 1, Tekton Impact Monitors, and they all produce solid tight bass.
