Worthy upgrade?

I heard a significant improvement in the sound. But, is the upgrade ridiculous in terms of the rest of my system?
 

Given that the goal of an upgrade is to improve one’s system, if you can afford it, I don’t see why not. You already heard “significant” improvement. The only question I would have is: could I spend less money somewhere else in the system and obtain better performance? Keep in mind that the rest of your system will most likely change too overtime. That’s the nature of the game. My 2 cents: significant improvements are not usually easy to come, thread wisely. 

My 2 cents..The MacIntosh is your weakest link. Restaurants that make everything generally don’t do it all very well, separates is the way to go. Trying to prop up Mid-Fi with wires is subjective and can be an expensive rabbit hole.

Spend your money as you wish, but wires make no objective difference.

What do you consider ‘significant’ as it relates to the Tyr 2 cables? What did you hear? What tech is different about them vs what you already have that would account for a difference (especially a significant one)? 

I don’t understand the engineering differences. The only thing I know is that the music cleared up with the Tyr. The Frey did a good job of presenting the music, but but with the Tyr the music seemed more transparent. I could more easily tell where the performers were located in the soundstage. 

Thank you for your help and good questions
