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?

Brilliant, AL. Looking at the impedance curve, your solution makes so much sense.
Ya it's sounding good my friends! I'm thinking of which speaker cables to get for each frequency range. Would it make sense to go for a "lean and tight" cable for low frequency and a sweet high frequency cable for the highs. In other words ask myself what I want most out of the two frequencies. Or would you guys recommend using the same cable for both ?
I'd use the same wire for both myself at this stage jut because that will keep things simpler. You can always experiment with whatever variations you want from there later.
I think what makes sense right now is to get used to this new sound. Then consider my next option. What I've noticed so far is that the bass issue has been removed at the 9 o'clock volume position and only starts to become a problem at nearly the 10 o'clock position. Which in my room is quite loud. So this has definitely improved my bass issue and I feel confident that I can manage this issue with a few more tweaks. Id love to try room accoustics as I think it is a must for any situation but I can't do that just yet because I'm unclear with my living situation. So I think a rca interconnect might be the next thing to consider.
