So far I connected my Nexus 7 via Bluetooth to a Nude Audio "Super M" while playing songs from Google Music.
But it doesn't work without hiccups... Lot's of buffering.

So this LMS => SqueezePlayer combo might be a better option.

I'm just not 100% sure if my NAS has enough power for the downsampling?!

The downsampling that I was referring to was the result of the fact that the iPhone does not play 24bit/96kHz files so LMS was downsampling the files to 16bit/44.1kHz. If you are using standard CD resolution (16bit/44.1kHz) files or mp3 files then there would not be any downsampling. I would give the LMS/Squeezeplayer combo a try.

Hm? iPeng does play 24/96 natively.
Did you maybe enable bitrate limiting?

Maybe it was playing the 24/96 without downsampling and I just didn't realize it. Is there any way to tell the bit and sampling rate of the file being played on the iPhone?

Sure, it's in the context menu for the current track under "more info"

Just as a curiosity, wouldn't LMS downsampling from 96 to 48 be a simple puncturing of every other sample, so very limited CPU requirement ? (no spectrum aliasing expected)

[pippin]

LMS uses sox which does rather complex interpolation and actually eats quite a bit of CPU in the process. Even more than MP3 encoding and dramatically more than FLAC encoding.
Keeps surprising me, too

Yes pippin is right LMS does state of the art downsampling when a player needs it it's inaudible to the listener a very good choice.

But if your server can't take it that's a problem .

Very very old server versions >10 years ago ,that where around at the time of slimp3 and SB1 might just dumped 1/2 of the samples , but at those time squeezeboxes where fun gadgets before anyone at slimdevices realised that it had hifi potential ,that came with the SB2.

Agreed but in the special case of 192/96/48 there is no need for filtering, so I was wondering if that optimization was there and could help by setting downsampling to 48 instead of 44.1

There is always need for filtering for various reasons, but I'm afraid I can't explain it very good .
Simplest case there is signal content even if it's noise above the nyqvist limit for 44.1 or 48 k (22,05khz , 24khz) or in practice a little bit lover ,this will aliase back into the signal if you just drop samples . Therefore they are filtered before downsampling . There must be no signal content at all above the nyqvist limit of the target sample rate .
