Best multi channel amp and processor good for 2 channel listening.

Eziggy,

What is the price range for AudioQuest?

I guess I’ll start another thread for cabling at some point if there isn’t one for a broader scope on the topic at some point.

@maguiar 

Overall I found Transparent cables better than Audioquest but would generally cost lot more than Audioquest. All Transparent, Audioquest, Shunyata Research, Kimber Cable, Nordost, etc come with wide price ranges starting from couple hundred dollars to tens of thousands of dollars. For example, Transparent Wave speaker cables, which is an entry level, retail for $250 to $300 per 10 foot pair whereas the Transparent Magnum Opus speaker cables cost at least $65k per 10 foot pair. 

Shunyata Research also makes outstanding cables and AC power products but are very pricey. Shunyata products are also used by many professional advance mastering or recording studios eg Abbey Road studios, etc. Lot of hospitals also use Shunyata AC power products for their highly sensitive medical equipments. 

Furman AC power products are good but I think the Audioquest Niagara and Shunyata Denali or Hydra power products are better than Furman IMO. 
PS Audio also makes excellent AC power products. There are countless other options out there. 

maguiar,

@caphill is spot on, there are ranges in AQ much like all cables.  Choosing manufacturer and line comes with demoing and preference, more important how one cable works in one system but not well another no matter what the price.

There are so many different threads on cables and so many schools of thought.  People have different opinions.  I can only speak to what I have heard personally and analog interconnects/speaker cables make a fairly noticeable impact in my system. I recently did some cable comparisons with non-audiophile friends and they heard the difference immediately, enough where there was a discussion on pros on cons.

I definitely agree with @auxinput's recommandations on solid core conductors.  For AQ, I would recommend the copper Water or even better Earth.  Preowned you can find on the marketplace ~$300-$600.  If you need more resolution, then silver but pricing goes up 2-3x across manufacturers.

I own a Furman IT-Reference 15i and think it's great.  Though I haven't gotten into the power side as deeply as speaker/interconnect cables.
At some point I want to demo the AQ Niagara and Shunyata products.  Almost everyone I have spoken to who has tried them really liked them both.  Furman shouldn't be too bad in comparison since their lead design, Garth Powell, left to join AQ a little while back.  He designed the Niagara power products, cables, and recently helped in the design of the new line of speaker cables.  The AQ Thunderbird Zero speaker cables I own are the most resolving copper cables I have heard.

My recommendation is build out a balanced system and not focus on just one area.  From my experience, it all makes a difference.

@caphill, do you run your amps through conditioners or directly to wall?  Some manufacturers recommend going directly to the wall, but I imagine with the higher end Shunyata and AQ conditioners it could be beneficial.

One really good option if you want a "pure silver" cable is the Audio Sensibility "Signature Silver" interconnects.  It uses all OCC solid-core silver conductors (20/22/24 awg sizes).  I used to run these in my system before I went to all copper.  It is in Canada and lists CAD prices.  A 1 meter XLR pair would be about $1,000 USD.  For the money, I don't think you can get a better "pure silver" cable.

However, I would not recommend their Statement and Impact lines because they do not use solid-core conductors.  Their Impact line actually sound pretty crappy (even though it uses OCC copper).  I have tested that in my system.
