Top resistors


Many threads with opinions on boutique coupling capacitors, but very little consolidated information on the sonics of resistors. Anyone care to share their thoughts on the attributes of their favorite brands & types for specific tube and SS applications? How much of a difference does a good resistor make?

My interest in the topic increased after recently installing the latest Texas Components nude Vishay TX2575 in several SS and tube phono & LS components. This was a proverbial "Ah-ha" moment-- a stray resistor dropped into signal path here or there, surprising with an improvement that equalled or surpassed the impact of a switch to a top coupling cap like V-Cap or Mundorf.

This is sheer nonsense; the guy is simply misusing his scope - notice he's using a crocodile clip for one end and just the tip of the probe in the other. Because of the poor contact of the probe tip, he's going to get different results even if testing in the "same" direction. He's basically a fool of an engineer.
crocodile clip is chiefly British - http://en.wikipedia.org/wiki/Crocodile_clip

Moving on... it doesn't look to me the tip is attached to the lead, but I guess it could be; looks floating from this vantage point. Another interesting question is, why is he using the "alligator" clip in one but not the other; why wouldn't he be using the same thing on both ends.

More to the point though, do you really believe a resistor would truly measure differently based on "direction", as if it has some sort of partial diode effect? And the person who posted that link said it all made sense to him - what exactly made sense?
Could this also account for the "directionality" in fuses some claim to hear? Any idea if the HiFi Tuning fuses are [P]OCC or not?
