You don't lack bass, you have too much treble

@erik_squires 

So I’m listening to Jazz @ 65-70 dbs and a trumpet pops in @80-85 dbs and it makes my ears hurt. The same can be said for Saxophone, electric guitars and some female singers.  I currently have 6 absorption panels and furniture and CD racks for dispersion. Carpeted floor and a lot of soft things in my room.

I have tried 2 preamps(both tube hybrid), two sets of mono blocks (both sets are tube hybrid) and a Hegel H390 (that is on the warmer side) and I’m still getting that sharpness above @80dbs. My streamer is still the modded BS Node N130, going to the Denifrips Pontus ll and the speakers are still the KEF Reference 5’s.

Any thoughts?

@curiousjim You may have the speakers toed in too much. Many speakers are really designed for little to no toe-in, so the slightly off-axis response is a lot smoother.

Another thing to try is the floor behind and in the floor between speakers. Bare surfaces there can often result in a lot of hash. Also, most underestimate the benefit that treating the ceiling between speaker and listener.

Lastly, check the wall behind your head.  Try absorption or dispersion there as well.

Hi @erik_squires 

Thanks for the reply.

The speakers have maybe 1° of toe-in. I will make it zero.  The floor behind them is carpeted, but I will definitely try more absorption behind them. Behind me is almost no wall at al. There are two door size walkways and a pass through from the kitchen.

And,  I doubt very seriously that the wife will let me put any treatments on the ceiling, but I can always ask. 😁

Bribe her with a gift 2 days  before asking ...😁
