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 😊

Turn all drivers 180 degrees . Then buy some 
nice speaker wire also same brand interconnect 
that you can afford .  Then 
 enjoy.  You will get bombarded with Speaker wire in this form   Just get the first Nice wire you see   so you don't go nuts over it all   anything above Monster will serve nicely 
This kind of talk is cheap weed talking.  Never think like this ,,,,,,,,  Any additional expense for supposed higher grade wire is a waste of money. It’s a total snake oil business.
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 .
