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

Try wiring one speaker out-of-phase. You state speakers were rebuilt so maybe the tech put one together incorrectly (hey, we're only human).
Use a flashlight or 9V battery to test phase. The woofer should move the same direction for both speakers.
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.
