for what its worth

Have your cables cryo'd and you will hear another upgrade. It is one of the best bang for the buck tweaks IMHO.

The better your equipment, the more easily you will be able to hear the difference between cables. Usually with the last bit of improvment cost goes up exponentially. A new piece of gear that costs $1,000 might gain you more than $1,000 in cables. In the end, every bit adds up to better sound.

There's something happening here
What it is ain't exactly clear
There's a man with a gun over there
Telling me I got to beware

I think it's time we stop, children, what's that sound
Everybody look what's going down

There's battle lines being drawn
Nobody's right if everybody's wrong
Young people speaking their minds
Getting so much resistance from behind

I think it's time we stop, hey, what's that sound
Everybody look what's going down

What a field-day for the heat
A thousand people in the street
Singing songs and carrying signs
Mostly say, hooray for our side

It's time we stop, hey, what's that sound
Everybody look what's going down

Paranoia strikes deep
Into your life it will creep
It starts when you're always afraid
You step out of line, the man come and take you away

We better stop, hey, what's that sound
Everybody look what's going down
Stop, hey, what's that sound
Everybody look what's going down
Stop, now, what's that sound
Everybody look what's going down
Stop, children, what's that sound
Everybody look what's going down

I agree that the cables matter more as the equipment gets better. A really good cable could actually make less expensive gear sound worse, since it will uncover the cheaper gear's shortcomings.
