Tonebender MK II cap choices

[mordechai]

I have seen many very good quality builds using Philips (or Sprague, or Vishay) orange drop caps for the .1uf and two .01 or .015 caps on a MK II  circuit.  But I am wondering if there is any downside to using these blue caps, which look like they have decent specs:



Would these perform just as well as the (somewhat pricier) orange drop caps of the same value in this circuit?

I don't see why they shouldn't perform.  But let's face it, the colour alone confers a whole heap of mojo!

Could I add the voltage rating..?? 
(a 16V cap is less mojo than a 630V one which, in turn, is less mojo than a 2.5KV one..)

I think that you should not pay attention to the brand of capacitors, the material is important - ceramics, film, electrolytes, but there is already a settled opinion and it is beyond discussion.
If you compare the sound inside the brands, most likely you will not hear the difference or it will be very small (catching fleas, as they say in my country), as well as the difference between different models of transistors or operational amplifiers, there are more marketers myths than truths.
Not so long ago, blue Epcos were popular with us, but judging by the forums in the USA and in Europe, they are not very much quoted.
