I'll also go with Samuel's account. however, you can and will experience different sound characteristics depending upon which cord is where.
the Hydra is not an active cond. Passive only. Just a filter. I've tried a couple types of pasive filters Shunyata, and PS Audio. both have their pluses.
On my amps, I run a lesser priced pair of PCs off a PS Audio Duet, which is supplied by an Elrod Sig III.
On the sources & preamp however, I run the taipan helix alpha to the pre, and a VooDoo tesla II to the CDP... a VooDoo Black Dragon supplies that particular Duet.... so how you set up things will vary on what you feel is good for you.
You're just gonna have to get some or one, keeping all others stock, and see what happens with that new aftermarket wire supplying your Hydra... and go from there. gee, that might be the only one you'll need.
