Right Angle Power Cord's

I would just get rid of the Levinson as if the engineering of the IEC connector is that bad to hide it under the unit just think what a mess they have made of the rest of it! That probably isn't an option so be advised that all the accessory power cord makers are familiar with the needs of the Levinson and offer right angle cords.....

Now, Bob. I have one of these preamps and it is a really excellent design. I believe the reason that they put the power cord there was two-fold:
1) there is not much room on the back-panel for an IEC connector
2) it allows the signal paths to be even shorter by removing the power-supply stuff from the back-panel area

BTW, I doubt if an improved power cord will make much difference. The PS inside is undoubtedly a good design.

Your two arguments make no sense whatsoever.......They should make room for the IEC and the shorter signal paths that we hook yards of input and output wire onto?.........Do a search on Audio Asylum as some cords make a significant difference used with this unit.....What makes the Levinson power supply design so good?

I dont know how good it is. I tried some different cords a long time ago and they didnt seem to make a huge difference. Maybe your cord or my new cord would.

And for the signal paths - the reason that they need to be short is because the intermediate stage drivers are not designed to drive capacitance. Only the output drivers are really designed for this. Also, the FR4 circuit board has poor dielectric absorption compared to air and Teflon used in most good cables as dielectric.

A low inductance/high capacitance power cord will do wonders for the Levinson which uses a toroid tranny as I recall......This is due to capacitive coupling between primaries and secondaries on toroids as all the high frequency crap is passed right on through with this tranny design.....Regarding circuit paths vs signal paths your point is well taken and few designs use real wire for signal paths as God and Miss Lily intended.....Costs too much and is tedious to put together a unit this way using small circuit boards and lots of real wire.....Some old timers still build things this way :-)
