Might be going for Naim Nait 5i but....

I want a good integrated amp and I really don't like seperates that much..
For me it seems like the Nait 5i is a better choice soundwise but not functional wise than the Nait 5. It seems like the Nait 5i is better because Naim themselves claims it's the best integrated amp from naim yet, it has more power and a shorter signalpath throughout the amp because of the passive preamp which also makes the amp cheaper..
So if you don't need a lot of functions which you don't get with the Nait 5i the 5i seems like a good choice. Because you pay for sound and amplification and not for functions and upgradeability...

I really would like to try Naim, but because I'm a integrated amp guy I will have to go for the Nait 5i or the Nait 5. But I don't think the Nait 5 has enough power so it has to be the 5i.
The 5i is a pretty cheap amp but how does it compare to more expensive integrated amps? It's a pitty doesn't have a more high-end integrated amp...Currently I have a Rotel RA-1070 and could buying a 5i be a downgrade?

My room is about 8-10 sq.m. big and I don't need all the power from the rotel. My dvd-player is a Philips 963SA with new powercord and Aurios 1.1 feets. It performs VERY VERY good for the money.
Speakers are Elac CL310 Jubilee Edition which is a pair of special edition speakers with only 250 pairs in the world. The changes from the ordinary CL310 Jet are better components on the inside, even better box, WBT speaker terminals and there might be more too...I'll post some pics of it..

So finally..What are your opinions? is nait 5i only a entrylevel amp or can more serious musiclovers have it too and be satisfied?
Can you tweak(better powercord, new feets, etc) it to sound better?
Would really appreciate your opinions!

Thanks!
