Hello, I m about to purchase a new audio interface and replace my old one ( Focusrite Saffire, the old one , the white) in my home studio.

so this are my demands:

The most important for me is to have as lowest ASIO latency performance as possible
I don't care about mic preamps at all since I m working mostly with virtual instruments (In a very rare cases I can still use the Saffire for  that reason)..
I need at least 2 analog inputs and  6 or more analog outputs( since I usually work in 5.1 monitoring speakers and my budget doesn't allow me to  spend extra money for a good DA converter at this moment).

I ve done a lot of research myself and I considering my demands  I have 2 scenarios:

A. purchase RME Multiface II and the RME HDSPe PCIe
or
B.purchase RME HDSPe AIO and the RME AO4S/192 AIO Expansion Board
( so I can have 2 + 4 analog outputs I need)

Does anyone has an expirience of both interfaces  and could advise me?
According to your opionion s RME HDSPe AIO a (much) better audio interface than the Multiface II regarding my demands??or should I go for Multiface II and take the advantage of having an external panel to connect the cables instead of connecting everything on the rear panel of the computer?
Maybe you can tell me a third option I have to consider ??

thank you
