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

Ahhh, well based on this review:

I could see you getting that. Before you go nuts, try the reverse speaker test. Put 1 or both speakers at your listening location, then walk around possible speaker locations until you hear the best bass.

Then, of course, reverse.

Another question. Is this the first full range speaker you have in the room?

If so, that may be the issue. Talk to GIK Acoustics or Michael Green.

Best,

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.

It's NOT the Hegel. Hegel amps are fantastic.
