Crossovers

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

Mental - I also found the dh-labs to be an excellent toslink. I have three on
different components and they are very clean and crisp :-)

That was after trying Chord and Van den Hul products - they paled by
comparison.

If you are going to look at the KLEI Harmony RCA range - start with the Silver
Harmony for analogue IC's.

The Copper Harmony are very good for digital IC's - I've tried them with the
spiral architecture and they worked better than my purpose built 75 ohm
cables.

They do work very well for analogue, but the Silver Harmony and up are much
better at analogue.

The nice thing is - on the right cables you actually hear the improvements
quite clearly from one model to the next - at least on my system.
- crisper dynamics
- wider/deeper image
- deeper bass with more control/texture
- extended top end with more clarity

They should sound really nice on the Krell/Oppo combo
