This is not a mission critical application and will not be used regularly. But, I would like to get the best I can from my (USED) but newly purchased Denon DRM-710 cassette deck. Unfortunately, there is no room available in my HT rack. So it’s going downstairs in my back up system. The length needed is approximately 30’. I’m considering using inexpensive cables like two Monster Standard Audio Interlink 100 (19.7 ft) & (13.1 ft) Interconnects. Of course I’ll have to use female-to-female adapters in the run. How much signal loss should I expect? Would stepping up to the Interlink 300 or 400 correct the problem?
