recommended speaker cables and interconnects

Audio Envy. Their new(er) ribbon type has incredible resolution. sounded thin for about a week, then Bam. slammin tight bass with the great resolution. Pass 250.8 and Legacy Sig SEs. 1/3 the price of the wire they replaced. very happy with them.

I have a number of Straight Wire interconnects. These were recommended as my first high end interconnects. My first big purchases of interconnects. The sounded terrible in my system. This was forty years ago. I bought something else… anyway these have been in my cabinet for decades. A couple years ago, I found them. I thought, “what the heck… let’s see what these sound like?” I put the in to my system today… I was shocked.. they sounded fantastic… better than my DH Labs, Cardas, Harmonics,…. And a couple others. 
 

Analysing what happened. Well, in general, the interconnects were too good for my system. My system had too much high frequency hash and distortion and my speakers were extremely fast and accurate which these very high quality interconnects transmitted thorough the system. I ended up putting warm copper interconnects and a really warm Cardas speaker cable to make my system sound good. 
 

‘Thirty five or so years later… I imagine the current versions are probably amazing. I would check them out.

Another vote for DH Labs.

Synergistic Research "Foundation" series seems to be a sonic bargain as per online professional reviewers:

Not a sensible question OP.

Most people accept that interconnect and speaker cable changes can have effects on the sound.  These effects arise mainly because of the interaction of the cables with the active components they are connecting rather than by the attributes of the cables themselves.

Further, each of us favours a different kind of sound.

So it is useless and damaging to take recommendations as to which are the 'best' cables for every system and every listener.  You are very likely to be disappointed.

The only way forward is to listen to a lot of different cables in your system and choose the ones that sound best to you.

A dealer or widely experienced audiophile can help by using experience of different cables in different systems to narrow down your choice by eliminating combinations he knows are unlikely to be synergistic.
