but the note does not have good DAC though

i listen to music on my phone, and that bad audio worries me as I use good IEMs

so i am waiting till i can get my own hands on it and listen to some music before i decide

Talking of radio signal; I have a quadband router and I noticed the Galaxy Nexus picked up the 5GHz band with only 1 bar and the 2.4GHz band at 5 bars, even though nobody else in my area has 5GHz routers. I wasn't even far away from the router so it kind of defeats the purpose of using the 5GHz band. Is it the same for the Note?

I can say the DAC the NOTE uses was superior (initially) to the Galaxy S.
However the DAC on the SGS had open sources and VooDoo gave incredible performance because Samsung made a sloppy effort first time.

I can say the DAC/IEM is not great, but it definitely is "acceptable". Putting on Beats headphones, the quality doesn't improve too much but its still a nice experience. Anyone with qualms with the DAC/IEM performance would be an Audiophile, in which case I would tell them most smartphone audios are disappointing, only a dedicated media player would suffice.

The SGNOTE supports Wifi abgn + Direct. This means support for the 2.4 and 5GHz ranges. I haven't had any issues so far.
I've just googled it, and there are quite a few Gnex owners having problems with the 5GHz band --cheap part or crappy driver, or both.
