Changing the final cap will either give you a few low bass notes or not. The roll off is 3dB per octave. And octave is 8 notes. Changing this cap will change the frequency where the roll of begins.
Before deciding I will give you Paul Joppa's advice. Try both and see if you notice a bass roll off.
I tried a hand full of caps and cap combinations on my Eros. I ended up, first, with a single 0.22uF were the design was 0.47uF (it comes with a 1.0uF as an upgrade. I could hear no loss of bass from the stock 1.0uF. I preferred the sound of these well broken in KK Teflon 0.22uF to any of the alternatives. Some of those I tried were as large as 3.0uF and it made no difference in the bass of my system. It is time for you to give yourself a smorgasbord of cap flavors.
