We are a Marantz dealer and require XLR Cables for the Marantz AV7005 Preamp/Processor, MM7055 5 Channel Amplifier, MM7025 2 Channel Amplifier. they stand a chance because of the much lower price than other XLR cables. When they arrived I opened the package and checked the build quality. They seemed to us to be well made. I installed my home theater and music using these cables and am enjoying them. I'm sure you can make an argument for buying $200-$300 balanced cables, but I've found it difficult to spend more on cables than the entire amp and processor. I will buy them again for the next client install. [.]
