Sneaky DSM vs. Sneaky DS + Naim Nait 5i-2

Hey everyone!
I'm a hifi newbie looking into making my first purchase.
Due to a very limited budget, I have thought long and hard about my options and narrowed them down to two choices.
I was contemplating the following:

a) A new Sneaky DSM -> Dali Zensor 1 Speakers (or a similar product)

or
b) A Sneaky DS (source only) + Naim Nait 5i MkII integrated amplifier (both used) -> Dali Zensor 1

I mostly listen to anything that falls into the category of rock music except for the very heavy stuff and also occasionally some electronic music and hip-hop.
The sound I'm going for could be described as rich, emotional and involving.

Any advice or recommendations would be greatly appreciated.

Kind regards,
David
