only accepts 96khz USB-in tho. Would be nice if it supports full DXD and 384.
What does the expansion USB slot do? What can it be expanded with?

hey I think I know the answer Zeos. that USB port is for the included blue tooth receiver dongle (Nuforce calls this the BTR1) that is included in the purchase of a DDA120 -- here is the link to the data sheet on their site: http://www.optomausa.com/uploads/datasheet/BTR1-DS-en-US.pdf

This is correct. The slot is not a normal USB port although it looks like one. It is meant for the BTR1 Bluetooth dongle (included every time someone buys the DDA120). Reason for the separate dongle is that the chassis of the DDA120 is aluminum and the dongle works as an antenna. This way we can have more reliable and stronger Bluetooth connection. - Jyri/NuForce
Any suggestions for an integrated amp/DAC that has a sub out and would fit well in a surround setup?

I like integrated amps so have looked around at quite a few... not many come with a sub out. Also, they are not optimal for surround setup as they are typically just 2-channel/stereo sound. If an integrated amp has 4 channels, it's usually because it has A/B channels, and hooking 4 speakers up and playing A/B concurrently in the same room is just quadraphonic sound (not surround).
That said, there are integrated amps with "Pre-out" outputs which can be used for sub-out. The Marantz PM8005 is a great integrated amp, but runs for $1199. It has A/B channels, many output/input options, and tone control. It is also pretty powerful for integrated amps.
There is also the Maverick Tubemagic A1. This one is minimalist compared to the Marantz. It only has one stereo channel, a single analog input (besides line-in), and a single pre-amp out. It also pushes less power than the Marantz, but is still great for decently sensitive speakers. The A1 starts at $199. MavAudio also makes a Tubemagic A2 which is a class A tube amp with the same function as the A1. The A2 is not listed on their site, so compare to the very similar APPJ PA0901A tube amp.
The Nuforce DDA120 is different from the two above because it features a DAC.
There are 2 options for hooking up a subwoofer to the integrated amp:
Your best bet is to run the integrated amp's speaker-out to the speaker-in on the subwoofer. Then, send the speaker-out on the subwoofer to your L/R speakers. Your powered subwoofer most likely has a low-frequency bypass/crossover that filters the low frequencies to the sub, and the higher frequencies to the speakers. This route is required for the APPJ PA0901A as it does not have any outputs other than the speaker outputs.
You could also run the integrated amp's speaker-outs directly to your speakers, then use the pre-out on the integrated amp to the stereo-input on the subwoofer. This method would not take advantage of the low-frequency bypass/crossover function.

Slowcountry, thanks so much for your detailed suggestions. That Marantz with it's toroidal transformer looks top notch, but it's pricey as you mentioned. It also to my surprise doesn't have any digital inputs. About connecting a subwoofer, I think I would prefer using pre-out for that to avoid any sort of pass through for the fronts.
To clarify on the overall setup I'm looking at, I'm not trying to create a surround system with an integrated amp, but to connect an i-amp to an existing surround system to drive the fronts. This would give me the best platform for music, and allow me to go cheap on a surround receiver for movies as it only has to drive the surrounds. Downside of course is that it'd be complicated for the missus to simply watch a movie.
Does it come with a remote control?

yes
How would this stack up against the SMSL M8 DAC (just had a drop at $149) with a Topping TP60 amp (around $220 street) . Much more power and a much more advanced DAC, plus the TP60 has two switchable RCA inputs, so you can easily add a tuner or phono pre.
That's been my settup for a few months now and I love it. Amazing DAC and a transparent amp. In fact, I'd say the TP60 would make a fine drop by itself.

I was looking at this amp before buying PS Audio Sprout. The weak USB DAC section in NuForce DDA120 really turned me out. The DAC in there is two generations old and it cannot even do 24/192 on coaxial not to mention DSD... and its USB input is only up to 24/96 max. I have plenty of 24/192 files and didn't want to go for a downsample conversion. I think Optoma need to replace this amp with one that has more modern and future proof internal DAC.
Otherwise the NuForce DDA120 is a very well built and capable little amp and will suit people that don't have higher resolution files now and have no plans to purchase them in the future.
I prefer silver but it's sold out? Only one?

Had the disable option checked accidentally in our backend. Silver is definitely available! Sorry about that.
Been waiting for an stereo amp to show up here! Too many headphone amp drops. This is a very good omen. When they drop a small simple class D amplifier or tube amp, I'm going to be all over it!

I started a poll for ~$400 stereo amps here: https://www.massdrop.com/vote/Integrated-Stereo-Amplifier

This is actually better than Class D, an integrated amp where the D/A conversion and amplification is done entirely digitally. The only comparable product is the NAD C390DD. Not for vinyl cultists, obviously.
Looks good in silver but silver already sold out?
Now MD doing int amp too ? :) this stuff has good design!!!!
