Guys - If this input cap and resistor are simply acting as a high pass filter then why deal with the problem at the speaker end? Wouldn't it be better at the line level stage? This way the power amps wouldn't waste valuable resources trying to reproduce the most energy demanding information only for it to be disposed of? Of course to do it digitally before the DAC of any system would be optimum. Another consideration is that many of the valve amps you guys are using will already use coupling caps between stages to prevent DC passing - why not chage the value here and do away with the second one? Far more efficient and one less cap in any audio chain has to be a winning solution....
Quad ESL Cap mods
Hello,
I have a pair of Quad 988 I'm considering replacing the electrolytic 220uF Capacitor for a film cap...
For those who have done it -- what caps give you the clearest extensions in the highs and improved mids without mudding the low???
Also, who makes a 220uF film cap? All I seem to find is lower values? Is it best to wire a bunch of lower value caps together for a total 220uF (if so, should you mix electrolytic caps with film caps - like some modders do) or is it best to have a single 220uF cap?
I do see Mundorf has 200+uF caps in their Tube Cap line -- are these Mundorf Tube Caps appropriate for the Quad ESL application? how do they sound?
Thank you guys very much for any and all input into this, as I'm just beginning my Quad mod journey...
