Crossovers

Steve - also take the opportunity to assess the state of the internal wires.

Copper Quality has come a long way since they were built and it may be advantageous to rewire them as well, but don't go overboard with really heavy gauge wire.

Something like Furutech FS 303 should suffice, but separate the two conductors.

For the short runs in the speaker enclosure, cable gauge is less important but copper quality should reap benefits.

Mental - I was just really fortunate to find a technician that is focused on value and service and not on his wallet :-)

The first job he did for me was to rework my tube amp - gave me two upgrade options and recommended I opt for the cheaper of the two - strange but true.

Most places don't have the required skills to make those kinds of calls

Needless to say - He is never looking for work :-)

Mental - since you are into DIY you might want to checkout these PC's and IC's

Cable Construction

The power cables are very dynamic, contribute greatly to a much better image and allow the amp to exert much better control over the speakers - they are also very quiet

I have them on every component

Scroll down to view the IC's

For the IC's I use 24 awg solid silver wire for the signal wire and KLEI Absolute Harmony for the RCA's

They are very detailed, open, neutral, dynamic and spacious (great image)

You can use other RCA's, but I've found the KLEI RCA's work the best

They are not quite as good as the KLEI gZero20 IC's that I run on my analogue rig, but I do use them on the digital side and they will get you closer than most of the store bought competition
