New Audioquest cables equivalent to Audioquest to the old ones

@Dustin, it depends.  How would characterize your system, neutral or warm?  If neutral, you may get too much of a good thing with the Niagara and lose some of the naturalness.  If your system is on the warm side, then they may work.  Totally based on your preference.

What components do you currently have?  In my opinion, the higher you go on AQ silver line the more they make themselves transparent which in return will show any potential mismatches and flaws between components.

Dustin, I had the Niagara, in my opinion they have all the benefits of AQ signature silver (smooth and crisp) but they lack body (mostly in mid-bass).  Wind I have heard is similar.  Sky, Fire and up are more balanced.  I have compared Earth, Niagara, Fire, and WEL, the Niagara was impressive at first but I felt it offered less balanced than Earth.  This is my personal preference of course.

Totally agree with mulveling on all points.

I really like the Fire interconnects, great bang for the buck in the price point (pre-owned/discounted).  I would aim to get Fire over Sky for the reasons mulveling mentioned above.

Have you considered Earth interconnects as well?  While it may not have the resolution of the Fire, it is an amazing cable and could balance out your system as well at a lower budget.

I would avoid the Wind if you didn't like Cheetah.  It's going to be better, but I don think it would give you the bass that you felt was lacking.  I had a pair Niagara and felt the same. 

@edsky I imagine there will be some benefits, but I doubt enough for you to get the improvement you are looking for.

I think the Fires will get you that notch or two.  It is an excellent cable, I am using a couple of pairs myself.  You have to spend a lot more to get incremental benefits.  Only reason I am replacing one of my pairs is to move up to the WEL interconnects.

@Edsky, looking forward to getting your thoughts once you get them.

@Mulveling, couldn’t agree more.

I recently did a shoot out between Earth, Fire, and WEL cables between my newly acquired Lumin T2 and my Luxman 509X.  Earth is warm and forgiving, vocals are pushed to the back. Fire seems like “lifting a veil off the speaker” with crisp clarity and great bass accuracy.  WEL is a bit more spatially balanced. But exactly the same tonal characteristic as Fire. Pretty amazing actually. Almost same level of crispness for both, except the WEL has more depth and is more relaxed sounding.
