Help me choice Audioquest speaker cables

It appears AQ has not mailed the cables to my local audio shop, so in the interim I have created a list of possibilities using AQ cables without auditioning.

Speaker cables (3Ft-3.5Ft): WIlliam Tell (silver) combo, Thunderbird Bi-combo, Firebird Bi-combo.

Interconnects: 3-sets of Black Beauty XLR (1m).

Thunder AC plug (1x) for Niagara 5000.

Not cheep but would like your opinions especially if you have auditioned these cables. 

Thx

I have a pair of MC611s fed by the C2700. I'm using AQ Hurricane PCs, and AQ Tbird interconnects. To my ears, the cables just reinforce the MAC sound. Incredible bass and mid-bass and a liquid midrange. The highs are not as precise but typical of MAC sound. My wheelhouse is from midrange down, and highs are not important to me. I plan to experiment with Firebird IC to see what it would do for the highs. 

I would suggest upgrading PC to at least hurricane (which is the best value in AQ''s line). You are very performance-light on IC's (the Tbird is the sweet spot there). You have a reference preamp, and it should be treated that way. I can't offer speaker cable advice since that is my next journey.

I have been listening to the AQ Firebird-combo speaker cables in my McIntosh System for over a month now and am very pleased with fast deep lows and crisp detailed midrange/ highs. To my surprise swopping out these cables with AQ William Tell (silver) combo cables in my All McIntosh System they sounded as goos as the more expensive FB's cables. 

In my system, a 4ft pair of WT's will cost me 6.5k (with discount) vs. a 4ft pair of FB's combo for 15.4K, "there just wasn't enough difference". Both Cables worked great and I would recommend them both. For my Ears in my system and room conditions, "Silver was the way to go". I would liked to have heard the AQ Dragon-combo speaker cables in my system but $$ was prohibited for my budget and keeping the peace with my wife. 

Start with Audioquest Rocket 88, they are the best bang for the buck Audioquest cable. You can usually find a nice used pair for much less than a thousand dollars. 

Paying six grand for speaker cables is just ridiculous. 

I compared AQ Firebird speaker cable combo with AQ William Tell (Silver) speaker combo in my system.  IMO and my representative opinion, there was very little difference when streaming HD music. Considering the FB cables are over 6 times the price of the WT, we decided the WT were the way to go. I also discovered using spades at each end to connect to Mac mono-blocks and B&W 800D speakers provided a stronger connection (the banana plugs pulled loose, due to the weight of the FB combo).
