Title: Kiwame Resistors
Post by: KMokc on November 21, 2013, 02:21:19 PM
I have purchased a Quickie and want to upgrade the resistors. I have ordered Kiawme in the following:

Kit 1K - Kiwame 1K0 (2 watt)
Kit 4.02K - Kiwame 3K9 (2 watt)
Kit 475K - Kiwame 470K0 (2 watt)

Also Kit 2.2uF 250v caps - Obbligato Premium Gold 2.2uF 630v

Can someone chime in to make sure the purchased values are correct?

Thanks,
Kevin

I'm not sure what the 1K0, 3K9, and 470K0 mean below, but the 1K, 4.02K, 475K, and 2.2 uF parts definitely match the parts list..  Hope this helps.

You'll probably have a very tough time fitting 2 Watt resistors in there, but they will function in the circuit.

Give it some time to break in, and by the time you get new batteries let us know what you hear!

Normally I restrict carbon comps to a few specific functions, but the Kiwames appear to be exceptionally well made and are reputed to give a slightly warmer, more relaxed sound.

I thought it's also worth mentioning here that the resistors provided with the Quickie are Vishay/Dale RN55D series resistors.  These are military rated, very high quality metal film resistors that you will find in a great many $10,000+ Stereophile Class A rated tube preamps.  It does occur to me that the Kiwames may end up being a downgrade from what is provided with the kit, so YMMV.

IMO, really a matter of taste, not quality.  The Kiwames are as good or better, from a manufacturing stand point, as the Dales, PRP, etc.  Just a different flavor. They are definitely a bit warmer and I have never noticed in additional noise, even in my phono stage. I use them and like them!  So take my bias into consideration!

Dales carry a mil-spec rating, Kiwames do not.  Though this really doesn't translate into sound quality, it does translate into manufacturing quality control.

Or...there is simply no need for KOA to mil-spec them as they are purpose made for audio.  The Kiwames are rated 5%, but I have not found a deviation of more than 1% in those that I have used.  That is pretty good manufacturing tolerance and QA.  Mil-spec is simply that...built to the military specification, that does not, necessarily equal built better, just that it is QA'd to meet the spec so a manufacturer can bid.

Hmm, I looked high and low on their website, and there's no mention of these resistors being made for audio.  They are simply listed as a high power/reliability carbon film resistor.

OK...I yield...rephrase:

OK, guys, points made. Let's move on.
