I've had the speaker cables now about 3 weeks and I've got 50+ hours on them I estimate. If there is more improvement in them, well that would be a bonus because they are better sounding now than any speaker cable I've used in the past.
For those unaware, the cables come as 4 individual cables, a separate + and a - for each channel, and there is serious heft to these. These are pretty impressive to handle and look at. They are very well made and Bob sends along hookup instructions for those who might be confused. I will say the size of these makes hooking them up a bit of effort. The connector lead is reduced in diameter for the last half foot from the hose sized cable so that helps but it might be tricky to run these through a tight rack. My amp sits exposed on a floor rack between my speakers and my speaker connections pose no issue. I need to get some cable elevators.
One standout feature is bass support. I'm getting more bass extension and weight with these than I've ever heard in my system before.
I've never really been sure what kind of bass effects are used on the Lorde Pure Heroin album. My LP has always exposed a low level sound effect that has challenged my speaker's bottom range. I don't use a sub. It has in the past just pounded without a lot of definition. I can now clearly hear what is recorded and if by magic my speakers have found a new level of support that only a sub would have exposed. To be fair, I also have a new tube amp that is far more linear than my previous one, but I swapped the old cables back in once and that was the last time that is going to happen.
Highs are equally sweet seemingly without end but there is no glare or harshness. Loud trumpet and violin runs to the instrument's upper limits simply don't offend any more, unless the musician has issues. LOL.
Lastly and this comes through all the time, the overall macro level sound is very full but with amazing transparency. I really can't find a sonic fault, and certainly not at Bob's very fair price.
