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 😊
