Dale or Kiwame resistor?

Jump to Latest
#24
Hi All,

Fist let me thank all of you for the kind suggestions. In the mean time I did a test comparing a Dale and Kiwame resistor having the same 33Kohm. Just listening the speakers front with the same fixed volume rate ( not a scientific test ) seems that Kiwame it is less noisy despite I thought Dale should be.
So now I have set the Kiwame 33Kohm, but I plan to try the 30Kohm to see if the little ground noise blowing from speakers may further reduce or not and keep sounding as good as now. The theoretical calculation to have 5 Mv should use 25.4 Kohm resistor, but an high gain sounded better in my system. My Integrated has a volume with 99 steps, I usually listen with 35 step.

Best regards

This is a resistor in your phono preamp, then you have a further line stage/ preamp gain stage, then a power amp of some kind, followed by speakers or headphones. And you believe that the change of one resistor is going to be noticeable - beyond whatever gain change you're making? I'd be more concerned about the resistor wattage (assume small), tolerance, and size. Check those off, go metal film, and be happy.

Hi,

My test was referred mainly to the gain that do change the sounding as you quoted. The brand issue was mainly related, to the noise level since the Pre Phono may produce more or less noise. The resistor I have are of a little bigger wattage though I suppose not really needed for this application, but now is what I have handy. All my resistor are perfect match for both channels, precision is what the maker declare.

Once I set the Kohm i like most I shall check if there is any different sounding between the brand I may find or have handy.

Thank you for the suggestion and best regards

Kiwame only gained popularity because Thorsten " the head banger " was pushing them during his Korean Diyfisupply days. Although I'm deaf like a doorknob and woukd stick RadioShack resistors without second thought, for unknown to me reasons I developed allergic reaction to Kiwane. You just have to try them because we all have different kinds of hearing deficiencies.

Hi,

Found the below, not sure is 100% accurate, however just for sharing:

I have tried several resistors, some of them are best sounding for me and most of them sounds different if you change the dirrection on which you'll start the input signal.

Here's the result: (caution: quite long) 🙂 and sorry if my english not really good

AUDIO RESISTOR COMPARISON SOUND AND DIRECTION TEST

TAKMAN REX CARBON COMPOSITE
>> Bit edgy and hard sound and less detail, less bold than Riken RN std in the same direction but more organized
Click to expand...
<<< Sweeter, more detailed, more musical, more airy and bit more warm, tone more balanced and organized
DALE RN60 METAL FILM MIL SPEC
>> Quite neutral, detailed high and crisp, more bold sound than takman (or more like direct cable I guest), not as sweet as Takman but less edgy and breathe music more strong bass also + bit hard if compare to direct straight wire (less liquid)
Click to expand...
<<< Bit sweeter but less bold, airy too, clearer high bit, and more musical a bit, still have strong bass but little lean
RIKEN RMG CARBON (I like this resistor when it compare to almost all this reviewed resistor except TX2575)
>> Sweet and spacious sound, detailed and airy, good bass and warm mid bit laidback compare to shinkoh
Click to expand...
<<< As mentioned above but bit more musical, more breathe, but bit less definition and bit less dynamic
AUDIONOTE TANTALUM
>> Sweet and musical, not as much air as Takman (in reverse direction), good bass felt bit tubelike sound and midrange domination
Click to expand...
<<< As mentioned above but bit less bass leading edge (I need more test on this)
RIKEN RN STANDARD (BROWN COATING AND NO GOLD PLATED)
>> Bit sharp high, bit edgy / hard, but good definition
Click to expand...
<<< Warmer sound and bit woolly bass, more musical and rich, staging more wider and deeper (also compare to Takman) bit midrange domination
SHINKOH JAPANESSE TANTALUM
>> Sweet, detailed and airy and have big dimension in sound stage, quite neutral sound and draw me to music deeper (I feel overdominate in midrange compare to Riken or other neutral sounding resistor and then I decided to remove it and substitute with neutral sounding resistor) + slightly thinner sound compare to straight wire but calm presentation and leaner bass.
Click to expand...
<<< As mentionded above but bit warmer sound (coloration I think) and bit overdetail high (edgier)
MILLS WIREWOUND 5 WATT
>> Neutral sound, airy and dynamic sound, but not as sweet as tants, leading edge also in good side
Click to expand...
<<< Less definition a bit but seems sweeter a bit / warmer (need more test)
KIWAME CARBON 2 WATT
>> Bit noisy and high more apparent, other are quite neutral (need more test)
Click to expand...
<<< Bit sweet and detailed also more airy (need more test)
KOA METAL FILM
>> Sound more like Dale RN60, detailed and airy, bit sweet also
Click to expand...
<<< As mentioned above but less bass, bit bright side but not sharp (need more test)

VISHAY NAKED Z-FOIL TX2575 or Z201
>> This is what I say about, almost perfect resistor, the sound is all you wish your audio equipments sounds, imidiate, harmonic detail, open, detail but not sharp high, great bass, musical, neutral and smooth mid but not overly sweet, great dynamic, clean sound and fast Very Recommended for upgrading the effect almost like you change standard capacitor with much better one. My only complain is it added bit bass to male and female vocal, makes it bit thick. I never try other direction since it says no direction because of laser etched foil technology is almos equal on both side.

AMTRANS AMRG 2W CARBON RESISTOR
>> Compare to riken RMG this resistor bit more open and more neutral but less lusher. Better in music description and more musical compare to dale metal film. For musical taste I like riken than this amtrans.
Click to expand...
<<< Less neutral and less lusher (bit forward)

Adelmo, you mentioned in your first post 36 Kohm, I assume this sets the gain you desire.

Now consider a few 'flavours'
1/ kiwame - carbon comp
2/ shinkoh or audionote - tantalum
3/ dale or caddock - metal film

you could follow amplitude's suggestion, I tend to use stand off solder posts for both loading and gain resistors for experimentation.

either way, have fun

Hi,

Does the longer wire needed to bring out form the case the resistor have some negative result to the load of the resistance? Now they have a very short path and attached to the board.

Tks n rgds
