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.

In what country is an, "alligator clip" referred to as a, "crocodile clip?" I'm guessing Oscilloscope is not your first language. The tip that is ATTACHED to the other lead of the resistor; is of the, "retractable hook" variety. They lock QUITE SECURELY onto whatever lead they are applied, and provide an excellent connection.

OK- In 40yrs of electronics; I've never heard the term, "Crocodile clip." Now- having looked it up, I suppose it was inevitable that someone would coin the phrase. The rest of my post stands pat.

Even in Australia where I come from - and where we have crocs, and not 'gators - these were known as "alligator clips".

The alligator has a rounded U-shaped snout whereas a crocodile has a narrower V-shaped snout. The clips more resemble an alligator's jaws.

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?
