If the holes are that small they can't be designed for resistors of more than 250mW or they made a design mistake imo.
MBA0204 are 25ppm parts, what power are those resistors dissipating?
LR1 are okay too, I have used them too. I also use SFR16S, they have thin leads too and are spec'd at 500mW
Is there a BOM, what did they specify to begin with?

If memory serves me right, the max lead diameter for all (unless 1W or more) resistors are 0.55mm.
My old carbon film are about 0.57mm, new metal film 0.55 or 0.6, some cheap chinese metal film 0.4mm, and Eagle 0207/10 pads are 0.80mm across, ie about 0.78mm hole diameter allowing for thru-plating.

I was talking about max diameter the PCB can handle.
It's a pity and frustrating that many amp designers on the diyAudio site go to great lengths to design fantastic amplifiers and then design a PCB that doesn't accommodate quality components e.g. the non magnetic type resistors from Vishay (RN & CMF Series), Takmann, PRP etc don't fit on most PCBs from this site.
