System too bassy - Primaluna & Usher


I'm looking for advice on how to tame my bass. Since upgrading my amp to the Primaluna Dialogue One from a low end Harmon Kardon, I've noticed my fatigue level from the bass has shortened my listening times drastically. That could also be because listening levels are higher because of the increased power. Regardless, I would like to tame the bass which these Ushers are known for.

THE SETUP:

Lossless Files
Apple TV > unknown decent quality optical cable to...
Rega Dac > low end Monster RCA cable to
Primaluna Dialogue One > $3 ft speaker cable to
Usher Be-718 speakers
VTI Metal stands

The room is 12' X 13' with one side open concept into the rest of the condo. The wall that the system is against is actually a couple of feet shorter because of the HVAC system, which puts one speaker in a corner.

I just got the Primaluna amp and I love the Ushers and do really like the Rega Dac. So I'm not willing to change those.

MY THOUGHTS:

I'm thinking of interconnects, speaker cables and room acoustics. I think room acoustics is a must regardless. Perhaps I do that first, then look at the total sound.

What are your thoughts?

Pics! Thank you thank you. View the 2 pics in this link that show how I've set it up for one speaker so far. I'm going to get back to it for the second. Let me know if this is what you're talking about.

PS. I was actually using the 8ohm setting the whole time so even more chance of improvement now.
I was able to fit 2 wires in the 0ohm banana plug. Also, I'm just using some standard wire that I had lying around to try this. I kept the slightly better cable for the low frequency and used the standard for the highs.
Deetothevee, the link in your last post requires a Dropbox signin. It apparently needs to be done differently for the pix to be visible to the general public.

RESULTS! I'm very happy (although maybe too soon) that I can report very significant improvements jn bass control and articulation! I want to give it time to prove that I'm not just hearing things but I have it a little louder then normal and I hear a more balanced sound. I did exactly what Al recommended with bi-wiring. Took some work but was very worth it. Wow I'm listening now and am floored at how much more balanced my sound is. Wow!! Thank you so much everyone and especially Al for supporting me and going way above and beyond. I've learned a ton.

You guys are incredible. I'll keep you posted after more listening time.
Brilliant, AL. Looking at the impedance curve, your solution makes so much sense.
