XLR question for bass

Thanks again for all the great feedback and suggestions.  I reached out to HD Axoustics as I think I'd be better served having a professional guide me.  In the long run, I may spend less money with better results.  If I try scattershot implementation on my own, I'm likely to just get frustrated.  

So glad to be a part of this great community.

I would suggest:

1. Ask the pro about what treatments actually help bass frequencies
   1. Bass traps work, but a rug will do SFA for bass modes.
2. Get a mic and REW to help with quantifying things
   1. Like what frequencies are you referring to as bass freqs?
   2. You could place a sub at the listening position and measuring with the mic at a variety of likely speaker placements. Reciprocity will make it the same as moving a heavy speaker.

• Get the speaker(s) in the right place first, then decide on a DSP or treatments.
• Treatments normally help more above 200 Hz, and DSP below 200Hz.
• Cables do almost nothing for bass.

To answer your question: No, XLR cables won’t do much, if anything, to improve bass response in that situation. You have a bright room with many hard surfaces. One of your speakers has no wall behind it for bass reinforcement. A sub woofer would help, but again, its a difficult room. Personally, I wouldn’t even try for high quality sound in that room. I’d employ a desktop system, listen in the nearfield and move those components into another room and situation that would support a better listening environment. Best of luck!

P.S.  Nice rack!

Luxman has fantastic tone controls try them. I have the 550ax2 baby of yours... Luckily my tannoys sound balanced (and also can change the crossover points on the front) but for the odd balanced album I just dial in the treble or bass I feel I am missing..... But generally leave straight 

XLR connectors don't have any intrinsic advantage over other connectors.  However, if the amplification devices are truly balanced, they will have an additional 6db of gain (doubling the voltage results in 4x gain).  Bass performance is likely most affected by (1) speakers, (2) room acoustics, and (3) amplifier-speaker impedance interaction.
