Which Component Needs to be Upgraded First


I need your help. I am looking to upgrade a component in my system. My question is which of the components is the weakest link and should be the first to upgrade. source: Sony 333es SACD, Pre-Amp hand built by Veda Audio - Dyna Hi Kevin Gilmore design, B&K ST 140 amp, Talon Audio Khorous-X speakers (the speakers are not going to be considered for upgrading. Thanks for your wisdom.

I think it gos a little beyond a simple cable upgrade,a decent conditioner can do much more for a system than a next up cd player or amp.Having that right youll hear just how good that gear is or isnt.I used to say that it was money that could be used better.The building blocks to start with got to be there.Thats my veiw like everybody elses two cents.goodluck
I have found conditioners to degrade sound and limit current/dynamics. I would have to say spend that money on direct 20 amp lines to your room before a line conditioner.
Also get a decent power cord.

I know many differ on opinions of power conditioners, so this is just my experience.
An Environmental Potentials EP-2050 AC filter/surge suppressor installed at your service panel will clean the AC to your entire house, and it will not limit current or dynamics.

At $500 (plus about $150 installation) it's also less expensive than the majority of audiophile power conditioners.
