My portable rig when I don't want/need isolation:
iPod Classic -> ALO Cryo Silver X -> Corda HeadSix -> Yuin PK2
Wrapped up in a HipoCase Ampsack by Jaben
Sorry the pictures aren't very good.
An iQube will also fit, but I might use velcro on the iQube so it will be more secure inside the Ampsack.
For the iQube to fit, the little velcro-attached pouch that holds small amps has to be removed.
