How do you have your CS's Strapped?  I am looking for the best way without necessarily tearing mine apart.  So far I have only tried connecting transformers in parallel, plugging the input into one rear rca jack with a jumper on the direct inputs to link the channels together.  This seems OK but l like a single select better unless there is need for a little more kick.

Also is this OK with 4ohm speakers like the MKII HDT?

Does one get significant better results by linking the input and connecting the x-formers on the interior?

What has to be done to maintain the correct input impedance (100k)?

Cheers,

Matt
