I use the aux out on my SignaLink USB to go to my powered speakers. I
can hear simultaneously what I'm decoding using the built in sound
card. I found this is the easiest to do and requires nothing other
than invoking the digital software I use, no cable changes.
Yes, you can use a "splitter" and amplified speakers to connect both
the sound card and headphones while maintaining separate audio levels
but that should not be necessary.
Similarly, one can connect the microphone to the computer (sound card)
and use the sound card's mute/select switches and analog monitor (if
available) to switch between mic and line sources but again it should
not be necessary.

exception, the mic input is used for input from the SignaLink. This very
same path is used for non-digital modes.
If I go voice contesting I can switch over to my Heil Pro headset
with mic and use a foot switch. I would do the same whether I used a
KX2, KX3, or K3. In fact, I did the same when I used my Orion II.
I use my KX3 for contesting, both as a base with the matching
KXPA100 or QRP on Field Day. I find that the radio is as competitive and
as any radio used for SOAB; the limitations in my scoring is operator
and not radio.
My experience in contesting, seriously, is not the KX3, but some of
the really poor signals and poor operation of the other stations. For
instance, the key clicks from Yeasu rigs are a real pain if the station
is strong. And, our local power company is the other limitation.

If I could get rid of the pauses, I could use the K3s built-in USB
sound card. The KX3 doesn't have one, so I'd need an external audio
interface or sound card if I wanted total voice automation with that
rig.
Unfortunately, since the KX3 (and KX2) lack dedicated Line In/Ln Out
jacks, interfacing headphones and a mic at the same time as a sound
card for DVK and/or RTTY/PSK is nearly impossible. That significantly
limits the suitability of the KX3 (and KX2) as a serious contest rig
even if one discounts the 20 dB *higher* transmit phase noise of the
KX3 (comparison of composite noise test data of K3/100 [Feb 2009 >
1 KHz.] vs. KX3 [Dec 2012]) or nearly double the keying bandwidth at
60 WPM of the KX3 vs. K3 (same two product reviews).
The K3 is cleaner at 1 KW than the barefoot KX3.

Has anyone put together a KX-3 kit. Is any more or less involved that
putting together a K-3?
I assembled both. The K3 is more involved than the KX3, but both were
straightforward. The instructions and parts lists are top-notch for both
rigs.
Anyone use a KX-3 in a contest and interfaced
with N1MM+? Any quirks/tips?
Yes to both. Both play very well with N1MM+. I haven't noticed any
quirks. On SSB contests with non-variable exchanges (i.e., no serial
number), I recorded messages in the KX3's two DVR memories. This allowed
me to operate in one mode (e.g., S&P or run), but I needed more DVR
memories to record messages for the opposite mode. The K3s has more DVR
memories, so I expect to be able to use four of them.
I did NOT record .wav files and play them through the rig for total
voice automation. I don't like the typical pause between spoken letters
and numerals. W....1....A....W FIVE NINE
NUMBER....THREE....SEVEN....TWO

My KX3 currently is in storage, and is not for sale.
Hope this helps.
