Upgrade Cables or Just Upgrade Equipment & Live in Shame?

I have a perfectly adequate hodgepodge of cables.

Basically a dog from each town.

 

Kimber 8T speaker cables

Mismatched length Transparent Audio I/Cs. DAC to Integrated

Basic Shunyata Ethernet cable. DAC to Streamer

Cable company Ethernet lines from Router to Streamer-Yes the ones from Comcast, Cox, Infinity etc-Amir says they are lovely BTW.

GR Research Power Cable + Assorted Pangea A9s

Some Chinese Fiber from TV to DAC.

StraightWire Digital- DVD to DAC

 

The only thing I have two of are the Pangea Power Cables!

 

Believe it or not I am pretty happy with the sound overall.

 

I use SolidSteel Tables and Dynaudio Stands + assorted room treatments.

 

Gear list just so you have a complete picture:

Pass Labs INT25

John "Fritz" Heilor Carerra 7 BE standmount Speakers

REL 5Ti Subwoofer

Innuos Zen Mk 3 Streamer/Burner/Storer

ANK 4.1x DAC

Balanced Power Transformer

Uptone Audio EtherRegen

 

If I avoid going the "Cable Envy" route I would instead buy 3 more subs

to have an array

 

What say ye???

Anyone with a system analysis ??
