Hi Graham,

Yes, I could, although it would make comparative listening difficult (I don't know how many times I swapped the Rothwells in and out just to be sure - because although their effect is apparent, it's quite subtle when trying to quantify it). I would only attempt this with recommended audio-grade components now that I know better (thanks to you). If the Rothwells don't have "toy shop" resistors in, I dread to think what they'd sound like if they did.

Apart from the Tyco ones you recommended earlier, are there any others that you'd consider using if you were to do something similar yourself? I wouldn't mind spending a reasonable amount if it meant less of a chance of spoiling the sound.

Cheers

If you could only get them....

Welwyn MFR4 "grown" in England. Or Philips MRS25 "grown" in Brazil - but you can't!

True, you can get Welwyn MFR4 but they're subbed to the far east and they're not the same. Likewise the MRS25 which are now under the Vishay marque also subbed out to the far east, and even they're obsolescent.

We buy giant quantities of a particular resistor when we find a good one which auditions up to par - it's a real pain. We have to keep sufficient stocks so the next brand that goes down doesn't bring us to a shuddering halt.

We often substitute the Tyco CFR resistors into a product when things get difficult on a particular value even though we like to keep the overall balance metal film, and there is no change to the perceived sound (or measured results).

But, for the DIY enthusiast it's a mine field and you'd be swapping every week, so I feel the CR25 (Tyco version) would be your safest bet.

OK, thanks again Graham for all your advice. I'll post back with news... Cheers.
