2? Last nite I hit the sack at 3+ tongue.gif

2nd patient cannot! Already been discharged! biggrin.gif Well balanced that one.I am going to use 2nd. patient to drive my woofers in the bi-amp config. The force (bass) is strong with this one.. laugh.gif

This is another verdict. Using a 10uH inductors is similar to having a 10uF input caps. The overall sounds that is.
Only some little details not quite the same. Small issue eh? wink.gif

I am comparing both right now!
My verdict? I will replace ALL the stock inductors! thumbup.gif

Findings:
midrange and high end got a little sharper. The cymbals sound are sharper with just the right attack/decay.
The stock 1uF input caps connected in series if were to be replaced with higher quality caps will definitely make this one leap to a new level! wink.gif
The depth got slightly better. Slightly better ambience.

Damn. Hitting the sack at 3 again tongue.gif

From what I heard, yes. Not much but there is. tongue.gif

Yes.. values also affect the output. It is part of a filter, remember?

The value is 0.47uF (C25, C27).
This one I saw being replace with a 220nF yellow coloured caps..

Great. We'll keep the 0.47uF then! Bought already! biggrin.gif
