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 😊

Start with a more powerful amp first and use the wires you have.  Later on, if you are enjoying what you hear, only then would I look into speaker cables.  
I also wanted to mention that I do own a Crown Base model PB-2 I used for my sound system for live music. It’s maximum output is 400 wpc into 4 ohms at 1khz with no more than 0.1% THD. (I have no idea what most of this means)

Would using the Marantz as a preamp and going into this be an option or would you advise against it?
Those M1's were fun speakers. You may really enjoy them. They are not finicky but they do need good current going to them to do them fair.
