Speaker and Cable Suggestions Please

Thank you all for your responses. I hope to read more. I may go with good cables first. I was thinking about Hologram II. The Audience AU24sx are out of my budget range, even in the used market. I want to keep speaker cables under $1,000. I was also looking at Avanti Vivace. I find the company's use of separate cables for the positive and negative an interesting concept.

I'm beginning to think I should just get better cables and bid my time, use my Focal Arias, and wait until I can better afford a more appropriate speaker for my room. It's just that my trade-in value for my Arias is never going to better than right now.

Thanks carlsbad2. My Aria's are at a relatively high sensitivity at 91db, that fact was why I chose the 75 watt output amp. I'm considering different speakers to achieve more definition and air in the mid and higher frequencies. In terms of volume, the Arias do quite nicely. 

Thanks marco1. I will be on the look out for those Audience cables.

Now I have a new question. As marco1 suggested, my Focal Arias operate at a nominal 8 ohms but at a minimum impedance of 2.9 ohms. I don't know what this means. Does the impedance fluctuate during operation? If so, what makes a speaker have a fluctuating impedance? Should I use the 4 ohm speaker terminals on my integrated or the 8 ohms?

Thank you all for your input. I learned some things from all you guys. For example, I had no idea that speaker impedance fluctuates, sometime drastically. I may give Fritz Heiler a call. His claim to fame is producing Tube-amp (SET amp) loving speakers with stable impedance. His speakers, however, are not the most sensitive. It will be one of the things I will ask him about once talk to him.

I will hold off on speaker cables for now and put the money towards better speakers. After careful consideration that seems like to most sensible course of action to take. If it wasn't for all of your contribution to my plight, I would have continued to chase my tail in my quest for better sound without even being aware of it. Again, Thank you all.

Thanks @marco1. Your sentiments seems to be the consensus in this discussion. I am going to try some old Paradigm monitors I’ve had in the garage for about ten years first. If they don’t work out, I will then try some Aerial Acoustic Model 6s I’ve had in my closet for a while. I remember really liking the sound they produced. If I wash out with those, then I’ll be on the look out for some used Dynaudio Contour 20i or may consider Fritz Speaker Carrera be. Sadly, Paradigm Persona Bs are way out of my budget. Thank you to all in this forum for your considered suggestions. I feel a lot more comfortable going forward.
