Speaker cabels for dark sounding speakers?

@simna put the chair back in and listen that might give you the answer.

Oh god, here we are again. Science deniers promoting expensive snake oil for auditory hallucinations. 40+ inane responses to an inane OP.
I don’t know why the learned among us have to keep repeating ourselves but here goes. Make sure the cables are cryo-freezed in a brass urn at exactly -63.2 degrees Fahrenheit for 17 days. Also marinated in olive oil to promote proper saturation (because cable saturation is a thing). And break in, cable break in is a thing too - so break them in for three years at monthly graduated volume levels. The cables should be bound in wraps and weaves in a beautiful light magenta color and be at least 2 inches in diameter (resembling a snake from the Amazon). Extremely important also is to make sure the arrows on the cables are pointed in the right direction - otherwise the little electrons get confused about which direction to travel. Lastly, and this is probably the most important to keep in mind, spend at least $20K per meter of cable - otherwise you absolutely cannot consider it either audiophile grade or even hi-fi.
‘Hope that helps.

Problem solved.

Moving the carpet a little gave me a little more parquet floor and I got more reverberation. It actually feels even better now than before I replaced the armchair with the sofa. The bass has been improved and sounds cleaner and it is easier to follow the tones in the bass area. The sofa works a bit like a base trap.

But I will still give silver cables a try when I get a chance.

Thanks for shareing your thoughts. Take care.

What are you current speaker cables? You may try Chord Epic which are silver plated OFC if you want to explore cables. As you have figured out, room furnishing and set up can bring a massive difference. It's good that you moved the carpet and resolved the dark treble issue.
