Recently I have buy some headphone jacks for my DIY amp, but I found that there are two types of them. One has 5 legs (1 for ground, 2 for left channel, 2 for right channel). Another has 3 legs( 1 for ground, left and right channel). Which one is better? Thanks for your attention

ic thanks Jan

Having read the circuit of Jan's Corda amp, I found that no matter which crossfeed is switched (even the fourth switch), crossfeed signal still present because of the 2200Ohm resistor connection to both left and right channel. My question is: How to eliminate crossfeed signal totally...

mmhardky where do you find HD 600 for cca$180?

www.richersounds.com sell it at 120 pounds including VAT, but it don't provide world-wide delivery service. I wonder where else can I buy this headphone around this price. Thanks for your attention
