Cardas or Audioquest for this System

Demo the cables and compare. Get a third brand in there for completeness. The cable company landing library is a good source. All you will get here is recommendations on what people have in their system. No one has your exact setup. 

I love the old Cardas model. 

additionally and separately, THe dealer i purchased the pass labs amp from had suggested "Synergistic Research" cables. I don't think he even sells them. But said they were his favorite speaker cable and would be good to look into them for this system. 

Anyone have experience with these cables?

Nagel, great points you've made. Let me say this and maybe it will help.

I have tried Cardas Clear Reflection interconnects with my system paired with cheaper $200 speaker cables and was disappointed. 

I then borrowed a pair of Clear Reflection Speaker cable and it sounded WAY better - BUT, it seemed to not be quite as dynamic as I'd hope and there could also be a little to much harshness (occasionally, not all the time) on the top end. I spoke to someone at cardas who told me that the reflection cables were designed for low efficiency speakers and that he wouldn't reccomend it for klipsch high effeciency cornwalls. 

Then i started looking into the audioquest stuff because i wanted more dynamics. But what you said about losing top end, that doesn't seem like something I want.

You mentioned you liked cardas - what cardas interconnect and speaker cable would you suggest with these components? 

OP Audioquest are energetic cables if your system is laid back it might give you a good match.Let us know what you think? Nagel has a good point.

Good luck @hifi_jed_1986 , I would've advised Cardas, but it depends on your preferences. Pass and Klipsch suggest your tastes are different from mine since they are laid back, especially in the treble. I crave extreme detail but with an EQ that's slightly bass heavy with good treble extension (hard to achieve wo EQ).

I own both cables in XLR and have Cardas Clear in speaker cables. My 0.75M Thunderbird XLR is fantastic except it kills too much treble and what I call the leading edge of detail. I've unplugged the dbs battery to make it halfway between an AQ dbs cable and more normal cable, and I still plan to sell it when I can get another used Clear or Clear Beyond. The biggest downside to Cardas Clear speaker cables is a slight restriction to dynamics compared to a more open cable geometry like Wireworld Eclipse 7 that I had before.

If you find the AQ too dead for your system and ears, Cardas would be a great change without going to detailed and bright cables. I've heard a number of people I greatly respect tell me they were unconvinced about the need for a full loom of matching cables that have since changed their mind. At least the interconnects and speakers cables should be similar.

@hifi_jed_1986  Wise decision!!!  Happy listening.

This is the info I was hoping for. Thank you all. Placing an order for AQ Thunderbird ZERO Full Range speaker cables and thunderbird interconnects 

Any experience that would suggest I should look at a different cable other than thunderbird line?

Third vote for Audioquest. They have terrific synergy with your Pass amp/preamp combo.

Likely Audioquest. On systems with a tendancy for being a bit hot or lean, Cardas is a better match. None of your components have that tendency. So probably Audioquest. 

Audioquest!!!!
