The sample rate does not make the sound ;-)
You will not be able to hear any signals above say 18-20kHz and I doubt that there is any relevant information in most of the recordings (except some high samplerate recordings that can be downloaded).
The benefit you get from higher samplerates is, that different analog output filters after the DAC can be used with less influence to the audible frequency range. This can be a real benefit in high quality DACs.
However if we look for a price range about 100$ I doubt that a analog crossover solution with OPs and a "highend" DAC that is significantly better than the build in miniDSP DAC can be realized, if it is even possible!
I second the recomendation from lduarte1973: go for a miniDSP + miniDIGI and you will have a great place to start and real fun equalizing your system;-)

If you are low about budget, you can try with only the miniDSP 2x4 card and then add the miniDGI card.
In this case the cost wil be more expensive, also the system will be a little more complex.
If you are really a novice ;-) sure you will enjoy the sound with only miniDSP.

>> The sample rate does not make the sound ;-)

I agree, take a look at this link miniDSP/vs DCX :

Red Spade Audio: Behinger Ultradrive DCX vs MiniDSP
"Conclusion : 4. All the units were transparent enough to satisfy the majority of DIY speaker enthusiasts."

I think now you have all informations to make your choice, budget can help ;-)

>> Maybe its an issue with the higher output of the 2x8 at the RCA terminals.

It seems to me that the builder of the NAO II has reported this in the MiniDSP forum. a part of his explaination was the higher analogic output on the 2x8.

i am pretty much sure that i am novice....!
because right now i am listening to bi-amped bookshelf speakers using foobar2000 with dspxover plugin 2way crossed at 3khz and i am simply 'blown out' by the sound quality! that proves that i am really a novice....

i dont mean to be a pain but i would go with the 2x8+minidigi , its worth the extra amount and allows you 4 way crossover , like i have 3 way classic speakers + subs

this reminds me my exprience with cd players , i had a sony cdp something i thought was already a nice cd player (laser died) , then bought an arcam alpha 7 and thought it was much better , then i bought the Cambridge Audio which i think is one of the best buys without riping your wallet.

sometimes it pays to spend a little more if you can , and soon you wont be a novice and crave for something better

but as Pascal says the minidsp 2x4 is already a good choice.

with foobar you can change sample rate to see if it matters much to you.

the minidsp 8x8 is the most expensive , if you dont need extra analog input , forget it
