Dedicated line w/ upgraded parts or power cond?

Thank you all for you input thus far. I will definitely be putting in dedicated lines and upgraded outlets. But before I decide on power cords, it seems that I should first upgrade my IEC inlets. Do you agree?

Yes you should.This will make it easier to judge differences in power cords.

Lacee, I've currently swapped mine out with Furutechs, do you know of another option?

Rockdanny - replacing the iec inlets on hi-fi components is not always as easy as it sounds - so before ordering, open up each component to ensure it is something you are prepared to attempt or pay a technician to do.

Also, better quality components may well have perfectly good iec inlets. So you may be changing something that may make little or no perceivable improvement.

Having said that I have replaced iec inlets and the improvement was quite noticeable, but that was in one of my DIY projects where I was certain the one being replaced was pretty crappy.

If you are replacing them with Furutech or Oyaide quality iec's, then at least you are assured of their quality and as Lacee points out - you have no doubts that improvements are due to power cords.

Also, ensure that making these changes does not void any existing warranties or UL certifications

Replacing a power cable - simple - plug it in
Replacing a part in a component - a little more to consider

This type of tweak boils down to how much responsibility YOU are prepared to accept :-)

Willie- thanks for your clarification. I will know more once I dig into the E=T set up. It is easy enough to have the cables reworked by the manufacturer if needed. I also don't know how this corresponds with US electrical 'code' requirements, which is something I want to comply with for safety/fire hazard purposes. I have usually worked with a licensed electrician whenever I do anything re wall power- unfortunately, most garden variety electricians know little about sound.
I'm probably going to use someone versed in studio set-ups and commercial wiring once I get to the next room- since I'm relocating from NY to Texas. My goal has been to find a residential property with a separate outbuilding, or the space to build one, dedicated solely to 2 channel listening. Such space is now at a premium in downtown Austin, but we haven't committed to buying a property here yet.
I gather you are in UK or EU?
