rwmeditz, It would appear that your unusually flexible integrated (kudos to Linn) might allow you to insert the 3.5's eq between the Intek's pre out and the Intek's amp in. Caveat: the manual does suggest dealer support when using the Intek's amp input!

This would free up all your inputs and tape loops.
As your using the minimum suggested power output into your 3.5's, you might want to consider the 20/40 Hz button on the 3.5's eq when playing tracks with loud deep bass. Damage is more likely with under powered rather than over powered amplification.
