Not sure about weakest links theories, but in my experience after speakers, upgrading the DAC has consistently been the highest return investment in audio. DAC + volume Control are the new digital premps.
Only problem with investing in DACs is technology is moving fast and price performance is coming down very quickly, so you always worry about spending too much money on a DAC when something better or something similar for half the price is just around the cornet. got to just commit and enjoy the music at some point though.
