Moode Player Help

[stree]

I understand that Tim and did consider the IQ AMP n DAC board, great solution.... But, there is a but......................
At the risk of clogging up a Moode help thread with non Moode help, I will outline what I intend. if anyone can see me heading for disaster a nudge would be welcome..........not towards disaster, but to help me avoid it!
Two constraints on this, first is available space, second is budget. This part is mainly imaginary, often there is no budget. Oh and a third, knowledge, or lack of it.
I have a Technics SL5 turntable 318mmx318mm footprint and this goes through a Behringer PP400 pre-amp, to a Muse 7498(?) amp with RC volume and USB and full size SD slot WAV FLAC player etc........Not interested in the WAV and FLAAC here, just the amp part and RC.
I also have a pair of KEF Cresta 11 speakers, bought new, about 100 hours use tops.
On the other side of the equation Win7 PC wireless router, D-link 320 NAS R PiB+ ( which will have a DAC, probably an IQAudio)........I have run this too through this Tamp and its fine.
Now, the amp has 1 pair of RCA inputs........I am considering using a 4 pole 3 way rotary switch, wired to a bank of RCA sockets, way 1 will be TT way 2 for Pi and 3 for AUX?
If I use the IQ Pi-amp+ this will cater for the pi, but there are no inputs for any external devices.........So I would need two systems and any switching to be done on the speaker cabling ( I assume)
If I use the Tamp method, I intend to build an oak plinth/case to sit under the TT ( Its all on a solid brick platform with an 8mm porcelain tile top, so flat and solid) and to house all the parts, with the 3 way switch, maybe the physical amp volume extended to mount on front and a screen for either artist-album-track display , or even a touchscreen 3.5" LCD so player can be accessed there too via touch.
I have 4WBT and 8 Rean RCA and 4 mtrs of shielded twin wire microphone cable available to make up interconnects custom to length. probably only a few inches each in length.
I will edit the atrocious spelling in a minute.......
Still gathering ideas before I start buying more, and cutting and soldering..............
