So I ask - what IC, power and speaker cables do you currently have?
Perhaps there is some significant gain that can be achieved by upgrading those, before you start on the components.
Some really excellent cables I would start with are the gZero3 IC, the gZero2 Speaker cable and perhaps the Gpower2 power cable from KLE Innovations.
if you search the forum for gZero you will see that i promote these cables a lot, but that is with good reason - I have tried most of their IC's and speaker cables for extended periods (over a month) and am yet to find a commercial cable that can outperform them.
One thing to be aware of - all of the cables above require extensive burn in - >400 hours in some cases - so patience is a virtue - but the rewards are many.
Great cables will
- extend your image and make it moire holographic
- extend the depth and control of the bass
- improve clarity
- improve dynamic response
You might also want to investigate power outlets, dedicated lines and distribution boxes.
And finally - take a look at acoustic room treatments
Components are just one element in a very complex audio equation.
Just a thought - Steve :-)
