Do not buy either of them until you have your new system in place and get accustomed to the new components. You will be introducing too many new variables into the mix and will not know what part each is contributing to the sound. Use the cables you are currently familiar with and introduce each new component separately so you can gauge what each one brings to the overall sound. Only then should you use the cables as a way of adding or manipulating the sound in any way. Once you have a feel for what you are looking for after breaking in your newer stuff you should ask again for our recommendations. You are building a system not throwing together a bunch of parts like Frankenstein.
