Ah... I said Pearl, not Pearl 2... I haven't actually listened to it all that much with the 2, as the original is sooooo perfect.

BTW- Anyone try a power cord other than a standard PC power cord?
I know this takes a back seat to so many other adjustments and tweaks. However, in 10 minutes, I made a simple power cord with 3-conductor electrical wire, Marinco and Watt Gate plugs. There was a nice improvement, particularly in the stability of the image. Also the sound stage opened up a bit more or it might just have been because the image was more stable.
Complex music became more interesting and less clouded.

Anyway, without getting to crazy about the topic, I'd like to hear your thoughts.

With those kind of results, you should make a tricked-out umbilical as well! Nice!

I use the less expensive Marinco models and even some Chinese knockoffs. they all offer better grip then any off the shelf stuff. Cannot hurt, and you have better control of quality of the contact and the wire. I also swapped my sockets for the red Hubbell hospital grade ones. It's not necessarily about sound improvement but better engineering for me.

I did. It's a CAT5 umbilical. Uses a CB radio connector or 4 pin DIN from Radio Shack. Build quality of the DIN plugs is suprising. Has a screw down nut to lock in place.
Could probably find the same parts from Mouser or Digikey for half the cost, but didn't want to wait.

Whole embilical cost around $16, not including the CAT5 cable.

You can find isolated ground outlets at Home Depot. They are the ones that are orange and have a green triangle on the face of the outlet.
My friend pickup the same thing, but with a built-in line filter from McMaster Carr for somehwere between $50 and $60 each.
Pretty much the same stuff as hi-end outlets, minus the cryo and Tesla treatments.

Can someone tell me if C22 is the cap used for MM loading?
Can it be removed for MC carts?

Thanks,

Vince

Yes.

Yes. In fact, most cartridges have enough capacitive loading through the interconnect that you can ignore the loading cap altogether. As always, however, refer to the manufacturers recommendation to Resistive and Capacitive loading.
