Resistor type

[Pegwill]

Hi Guys

I’m using a SUT and I need to put resistors on the primary side. I’ve used an online calculator and it comes out at 21ohms. So two things really

1) Do I go for 20 or 22ohms - I would be trying to use a 1% tolerance to minimise the differences between channels

2) What type of resistor, carbon, metal film etc should I be using. I would like to say that money is no object but of course that’s not true so a compromise will be required.

Many thanks

Hi William,
you can get 21 ohm resistors https://www.mouser.co.uk/ProductDetail/Vishay-Dale/CPF121R000FKE36?qs=sGAEpiMZZMtlubZbdhIBIOCYJVKraTh TyAhjvYMDhuU%3D

Were it me, I’d get these-

I'd recommend Takman carbon resistors - https://www.hificollective.co.uk/catalog/components/resistors/takman-carbon-film-resistors.html . More musical, less 'HiFi' than the naked Z-Foils and somewhat cheaper to boot!

[Ali Tait]

Yep Takman are good also.

Audio Note Tantalum, if they have the value.

Is that really £11 each?!

[Ali Tait]

And?

Nobody baulks at paying lots for foo caps.

You can probably get them a bit cheaper elsewhere, but Hifi Collective service is first class, and you can be confident you aren’t getting fakes.

But foo caps are rolled on the thighs of naked virgins in the dew drops of a golden dawn! Resistors is just resistors innit.
Personally I also like metal foil and metal film, low noise, tight spec, predictable performance. But then I haven't knowingly heard the resistor magic of carbon comps.

I do. But I'm a cheapskate. :)

.

I do!

The Takman are great but in critical positions I too savour the Z-foils (‘naked’) resistors. If you order them direct from Texas Components you can specify exact custom values and get them in tolerances of 0.1%, 0.01% and 0.005% (depending on value).

[Ali Tait]

Ah yes good point Mark, had forgotten that.

[Ali Tait]

I do!

LOL, fair enough!

They are indeed pricey, but I’ve heard them make real improvements when I’ve used them in the past, same with caps.

What were you thinking when you wrote that?

Generally foo caps cost crazy money. Just two in my DAC were £350. The Audio Note silver tants were acceptable in comparison.

Obviously it depends on value, But even so.

Que? I speak from personal experience, as always.

Up to the individual to decide if it’s money well spent. Yes it’s a lot for a resistor but it’s only 11 quid for heaven’s sake!

Not as if it’s the fortunes you can pay for say Duelund caps- I wouldnt myself. I did spend a couple of hundred on Path resistors and Jupiter caps for my Bastanis OB’s though, and I think it was money well spent.

Jupiter's are really good too. I have a sense the Duelands I have are more transparent, though. But since the ratings aren't the same it is hard to be sure. That said my perception is Jupiters are slightly coloured but in a really nice way as compared to Duelands.
