I understand the benefit of replacing the stock .22 uF (C101, C102, C201, C202) and 2.2 uF (C104, C204) coupling capacitors with higher rated and better quality caps. However, can someone explain the benefit of increasing the .22 uF cap to 1 uF and the 2.2 uF cap to 8.2 uF as is recommended in the rockgrotto upgrade kit?
Doesnt the increase in cap size cause a change in the frequencies that are passed in the signal path? I would think that the original values were selected based on the frequencies to pass and the impedance of the circuit at that point?

The current kit replaces the 220nF caps with 1uF caps and the 2.2uF caps with 4.7uF caps........ the reason for doing so? It sounds a thousand times better (as I have been told on more than one occasion). I'll leave the maths to the experts and simply say "sounds better to my ears"  Mike. |

Any more info you require before I ban your arse for promoting /spamming cheap Chinese clones?
I'll allow you 48 hours to read the forum rules and trust your next post will not be associated with Chinese Spam.
Mike.
