Upgrade speakers or DAC


Next upgrade is going to be either Front L/R speakers or streamer. Current speakers are Sonus Faber Olympica III, looking to upgrade to Il Cremonese. Streamer is Cambridge Audio Edge NQ looking to upgrade to dCS Rossini APEX.
Which upgrade will make the most significant improvement?

I used to say speakers but, the source is where everything starts and stops

if the signal is not very good from the start you can’t make it up down stream.
