Do speaker wires matter


I recently was given a pair of Mirage M1 speakers. All highs, mids and lows work but I don’t believe they sound like they should.

The tweeters are not giving the detailed highs. I am not sure if the mids and lows are where they should be.

i am currently using a vintage 2226b Marantz I just had restored. Impedance is 8 ohms and it only puts out 26 wpc. I know these speakers require A much more powerful amp. I’ve done a little research on this.

im wondering if the speakers could not sound as good because of the Marantz and/or also because of the speaker wires I’m currently using. I don’t know what gauge they are. They were given to me as well. Any advice would be greatly appreciated.

i did also find a Mirage technician in Canada who still repairs them if I’ll have to take that route. No turning back now 😊

Another Classic  He said ,, back in the 70's or 80's my brother in law sold stereo equipment.in those days he said that speaker wires don't matte! :::: In the 70,s 
who was making wire?? 
 early Mid 80.s   ok,   more and more manufacturers .
 Selling audio at Walmart don't cut it .  also who listens to a brother in law? 
  
I apologize for picking nits, but I believe those Mirage speakers are bipolar instead of dipoles.  I should probably have a pair since I am bipolar also.
Make all the difference in the world . Go with Kimber or Purist and there bottom line . And a "TRUE" bi-wire cable . Thats if you have a true bi-wire speaker? Take the speaker cable post off and trace it to the crossover,.separate  wires its a true bi-wire speakers .
Speaker cables do make a difference. For decades I scoffed at the idea and thought that just current capability would matter. For decades I used 10ga speaker wire bought at the hardware store. It sounded good ....until I bought some reasonably priced 10ga oxygen free copper speaker cable. Wow! The high frequency was better, symbols had better decay, a brightness without the harshness like the old cable. I did not have to spend thousands to hear this change. Also dynamics increased. I see many ads for cables way out of my budget. The brand was "installgear" and I am sure for most audiophiles is not good enough. I love music and demand as good of sound as I can afford. I have DYI speakers that bring out the best, or worst and not forgiving of bad recordings or original EQ being right. In my case, yes! Cables do make a difference. Plan this in your budget according to what you can afford.
I have both the Mirage 3 si and 2 si and Man are they POWER HUNGRY!!.I was in a mid size room and i just could not get them to wake up, the sound was sooo dull and lifeless, i tried three power amps from 150 watts to 200 watts!!! and i still had to get my fix back by going back to my Khorns,i Had Cardas speaker cables on them and still nothing, THAN I PULL OUT THE CROWN STUDIO REFERENCE!!! and my GOD!!!
the walls was PULSATING.they need juice. Michael Jackson's JAM was hitting so HARD my neighbor turned down his music to hear mine, YEAH BOY!!!
