Actually, I currently have the best phono of all, which is no phono. 100% digital, baby! ;-)
I'll freely admit that my audio system in the late 60s when carbon comps were the rule, was pretty poor by modern standards. For openers the source material was all analog, and that implies what we would now consider to be massive audible distortion in that part of the reproduction chain.
If you put the objective information in recent posts together, you may find that the noise and distortion in commodity resistors has improved by maybe 40-50 dB. That's pretty darn impressive!
The human thresholds of audible noise and distortion have remained appreciably poorer than even the garbage parts we had back in the 60s.
Sometimes, not always. See the Audio article from the 1950s, "The Sad Tale of a One Half Watt resistor."
These days, it's a non-issue except mentally.
This can be read at: http://www.tubecad.com/2007/12/23/The%20Sad%20Tale%20of%20a%20Half-Watt%20Resistor.pdf
A 1/2 watt carbon comp resistor with 4% THD is more of the exception than the rule.
Bad resistors were much more of a maintenance problem when they were carbon comps.
The article specifically says that the resistor measured about 100 ohms despite a schematic that said 47 ohms. It was broken, so this is obviously not how carbon comps performed as a rule. When replaced (presumably with a good carbon comp) the THD dropped to the expected value.
So, as you say sometimes and I might add a whale of a lot more commonly than these days.
IME bad carbon comp resistors can be produced on cue by simple non-destructively overheating them. This also has the usual effect of permanently significantly increasing their resistance.
Agreed.

arnyknot sure that is better ...btw me to more on dac this day,but is clear audible the difference resistor on cartridge load !
Changing cartridge loading resistors can cause audible differences but resistor quality has nothing to do with it.
Then something is broken. Seriously. Since the input resistor is shunted by the cartridge, start your troubleshooting there.
I'm trying to help you, since I've been designing and building phono stages for many decades, and have in recent years concentrated particularly on input stage loading effects, which are too often ignored. I'm not sure why that seems to upset you, but if you want to troubleshoot on your own, go for it.
SY thanks but my koetsu with Borbley phono sound very good ...
i'ts not difficult to understain that a resistor is a cap and ind. at the same time plus material and construction difference make for sure a difference in the sound , if is not the same cannot work the same . I use to taste ...I ear clear difference ,glad that I do
PS my cartridge setup and load are perfect!

If the capacitance and inductance are significant for that position, it's defective. Even a cheap metal film resistor will have capacitance several orders of magnitude lower than the input capacitance of a FET (even in cascode) and inductance orders of magnitude lower than the cartridge. So if changing the resistor makes a difference, you're either using some really terrible resistors or something is broken. Time to start troubleshooting.
SY my are general consideration ...don't tray with me please
if you can't accept that good resistor sound better is your problem
PS and please quote all:

Yeah I did all that silly sh*t when I was 18. For most people at some stage the realization hits that other things make an order of magnitude more difference.
