Audioquest Water interconnects

I do not have experience with those cables, but it would be helpful to know what you are using now. Personally I have steered away from Audioquest as I find the number of choices a bit overwhelming and somewhat mystifying. 

Thanks. I’m using cheaper Audioquests called Black Mamba that I bought many years ago from Audio Advisor. 

I absolutely love AQ HC power cables. Putting a AQ HC power cable on your Krell will be a game changer (1m is fine, if you can get it to work). It will also give you a bigger bang than ICs, get them later.

I know they are expensive but buy used and confirm serial nos. with AQ.

Dragon, Firebird and Hurricane high current.

I demoed the Dragon ICs and they weren't for me.

Contemporary Audio Quest power cables are nothing less than revelatory. There had to have been a redesign of their High end stuff a two or three years ago, because prior to that they were nothing to write home about. 

The Audio Quest cable with the boxes on them... tend to be much better sounding than their predecessors. I was listening to some of their top of the line ones yesterday (over $50K). 

Over the past decades, in part because of the incredible plethora of cables I concentrated on some well reviewed and respected brands. Transparent are my go to, Cardas, Wire World (I don’t buy them any more), Nordost, DHL as budget, and a couple others. 

You can find other great sounding cables. But with break in of over a hundred hours, often two hundred hours, evaluating them and knowing the basic characteristics, so to optimize your system becomes a gargantuan task. So, getting to know some very well known brands and their characteristics (house sound) makes the task more predictable although not simple. 

So Cardas is warm and natural... the warmer the more budget oriented they are, Transparent are not even slightly harsh but completely transparent, Nordost very incredible in their high end products with great transparency. DHLabs... surprisingly well balanced and good sounding for the money... I start here if I am not sure where to go.

If I had to build a new system now, I would use all of either Transparent, Cardas, or DHLabs, with power cords from AudioQuest. 

Since you have Audio Quest. I would try the lending library from the Cable company and compare Audio Quest with Transparent. That way you can confirm against something that is know to be phenomenal cables. Your system components look very well balanced, so you probably want neutral. If you are trying to stay cheap... go DHLabs... the best you can afford.
