Sorry! that's Gustard A18 Dac and not Guitars ! lol!

I currently have the best system I have ever owned. My speakers and probably my integrated amp are “forever” pieces. I am upgrading my two of my power cables one at a time, but am happy with the rest of my cabling.  I will make a significant upgrade to my DAC even though I like what I have (I heard an awesome one and must have it so saving my pennies!).  My turntable is 24 years old but it is still incredible.  Overall, I love listening to music in my system as it site and will be a happy old man if it never changes. 😁

Yes. Absolutely. 

i'm not really an audiofile. back in the early 70's i had a marantz 4300 with 4 bose 901 series 2 speakers. in the early 2000's i bought a mcintosh mc2205 power amp. in the early 2010's i bought a mc602 amp. and a mx132 unit. still have the bose.since i'm retired now, this will be my last system!
