The problem I have here is not that they recommend it because it makes an improvement, but what are they benchmarking against to begin with? What is the environment like in the house or testing environment? Where is the router/switch going to be located they are patching into? What's equipment/devices are around the switch or cable? Where does the cable need to travel between and what is the distance? What is the end device they are testing this with? What is the testing applications suite? Browsing through a bunch of reviews, I cannot find an example of where this is all provided.There have been a number of positive reviews of cables and switches from the HI-Fi press, including “What Hi-Fi”, owner of this forum over the years.
However, where they state a positive recommendation for an expensive cable or switch, how did they come to this conclusion.
I think in this case it's not necessarilly the cable, but i'm wondering if the performance is because this isn't a pre-manufactured XLR-XLR cable, but made up cable order from ebay. The cabling these cables was made from, the Mogami Neglex 2534 which looks to be a popular cable. Is it worth getting these sent off to be reterminated?No doubt the original XLRs were made with identical cable on both the left and right channels Jimmy.
So how could (working) cables have been the cause of any imbalance?
That seems more likely, though as you're suggesting, it wouldn't explain why the new XLR leads cured it.I wondered if it was the Volume POT on the Topping A90
