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 😊

I have been changing my speakers cables, from Siltech, JPS Labs, Acoustic Zen, Gotham Audio and I now ended up with the vintage WE cables. It always makes different when we switched the cables. It's all about the taste and the matching of the whole systems.
I use a quality 10 gauge speaker on everything in my system. Any additional expense for supposed higher grade wire is a waste of money. It’s a total snake oil business. 
People do not hear cable. It just makes them feel special having it back there. I’ve seen power cables that cost more than my amps. Silly. 
Those speakers are pretty nice but you need a heck of a lot more than a vintage integrated with 26 watts to drive them.  They are ridiculously low sensitivity.  And, being a dipole speaker, room treatment and placement becomes even more critical.  I guess it comes down to what you want to hold on to more....the Marantz or the Mirage.  But they are not a match.

Silly. .....     What is silly is this post .Id say if you honestly think cabling is snake oil either your system is junk ,your ears or both ..10 gauge wire,omg did you really just post that on an audiophile forum?
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
