Cable burn in


Hi all. I’m guessing that what I’m experiencing is pretty normal. But it can’t hurt to get some feedback. I purchased a DMS-650 from Cary Audio which is a DAC/Streamer. Since hifi folks have highly opinionated views on cables, nothing is included with the unit. So when I set it up, I had to scramble and I found the three conductor cable that came with a cheap Sony DVD player. Then I replaced that RCA interconnect with a much better quality Blue Jeans cable. Initially the increase in quality was apparent and obviously worth it. However the sound could be hasrsh on certain recordings. Various tracks had a harshness that wasn’t there before. I’ve been playing internet radio during the day for burn in. Now that harshness has vanished. Sitting down to listen last night, things were actually too warm. Some tracks sounded almost muddy. The sparkle was diminished in an obvious way. I am guessing that once burn is complete the sound will settle happily in the middle somewhere. Is that a reasonable assumption?  I’m also likely going to order power cables and an interconnect from Audio Envy or maybe some other companies to compare. The guy who sold me the Cary Audio gear is not a salesy guy, but he did pretty emphatically recommend some higher quality cables.

I responded about break in. See above. 
Everything matters…type of materials used, level of quality. 
I like OCC copper for interconnects and speaker cables. 
Remember though in the end you get what you pay for. 

I wouldn’t be wasting time on $40 speaker cables. Get your components straightened out first, then invest in good quality cables. 

@audphile1 +1, I agree, get the components and the room sorted out first and yes, in the end you get what you pay for.

Only mechanical things need a bit of run-in - speakers and phono cartridges.

Electronic gear also needs to burn in before it stabilizes. Amps, Preamps, tubes, CD players, anything that builds heat.

That has not been my experience with cable burn-in.  Once they go in a certain direction they do not tend to go back from where they came.  Just my experience FWIW, but you seem to have good ears so just trust them because, in the end, that’s all that matters.  DH Labs would be a good cable to try if the Blue Jeans don’t settle in to your tastes as they tend to sound neutral with good detail and without breaking the bank.  Best of luck.
