digital or analog volume control?


I am presently running my dac direct to my amplifiers using the digital volume control of foobar (for ripped cds) and MPCHC (for movies).  When I play movies on MPC it indicates playback at 32 bit floating point, and from what I have read, Foobar does the same, and both sound great to me. I am having a dac modified (Monarchy audio M24) and my tech has given me the option of direct out (like I am using now - with no analog volume control) or either an alps or ldr type volume control - at added expense, the latter the most expensive.  Is the analog volume control better sounding than the digital that am presently using?

I have gold plated connectors that pass GHz signals cleanly. Gold plate does not roll off highs.
Thank you.  Actually the dac is a monarchy audio M24 which is a dac and a linestage/active preamp  combined.  The modifications will be to both the dac and the linestage, so if I don't add the volume control (the original volume control will be removed no matter what I choose because  it was very poor quality) I will essentially have an active preamp with no volume control feeding my amp.  Not sure if that makes a difference. 
You may want to check with the person who is doing the modification.  If he places the volume control before the line stage, then you are good.  The line stage will have its own gain and voltage to drive the input impedance of the amplifier.
