Does Equipment Break In, or Does Our Hearing Adjust?


I’ve read many comments about how the sound quality of equipment improves after so many hours of use.  I don’t doubt what people are saying.

About a year ago, my wife and I were tired of not being able to hear dialog while watching TV.  Especially when there was background music or noise, we had a hard time hearing dialog.  Turning up the sound helped, but not very much.  The sound of the TV sounded normal to other people visiting us.

We bought a Zvox sound bar.  Setting it up, we could hear the dialog, but it sounded very tinny, almost irritating.  But that disadvantage was outweighed by being able to watch TV and hear what was being said.

Now, a year later, we can still hear the dialog, BUT, it doesn’t sound tinny anymore.  The voices sound normal, like people we talk to in real life.  It’s not irritating in the slightest.  This happened gradually over a year, so we didn’t notice it until we thought back to what it first sounded like.

My impression is that our hearing adjusted or became used to the new tinny sound.    Or, maybe the sound bar broke in to sound normal. But if it broke in to sound more like normal, I would have thought that it would lose the special effects that enabled us to hear it better.

Or even, maybe it was a bit of both?  Any thoughts?

As to three REF 160s’s. My dealer got one and thought I would like it… so he brought it over. I instantly loved it and asked him to order me one. He left the first until I received my copy. So, a couple months later, my unit shows up. We swap it. My new one was great… but one of the meters was weak… not a big deal, no hurry… several months go by. My dealer drops by and asked what I want to do… have him replace the meter or get a new one. I say, I don’t care, what would you do? He says, “get a replacement”. He calls ARC, and a couple minutes later a new one is on its way. So, in a couple weeks, I get a new one.

I can’t remember why, but at the beginning of this year my dealer (who has become a friend over the last twenty years) brought over the reference 160m monoblocks… for me to compare. I love them, so he has been nice enough to leave them. So, I currently have both.

These mono-blocks were early copies… not long after they came out. I went down to his store to hear Bruce from Audio Research introduce them. I immediately realized it was finally time to get a tube amp. I decided then to get the stereo version when it came out. It took a couple years or so, but they did, and I did. But having these monoblocks in my system is really gratifying, not only because of how amazing they sound, but because these were the very ones that I heard that caused the pivot in amplification for me… so, important for how my system sounds today. This very amp probably caused one of the most important pivots in my system of all time. My system is now all ARC and exceeds all expectations I have ever had in owning an audio system.

Hello tcotruvo.  Equipment, cables, speakers, etc do "break in."  While Nordost uses 8 or 9 conductors for each leg of a cable to a speaker, you can buy 50 conductor ribbon cable ($0.65/foot) and have 25 silver plated conductors in each leg of "speaker cable" and enjoy excellent performance (use every other wire for + and the others for -). I mention this because the cable is used to carry very high frequency data betwen mainframe computer cabinets and uses an insulating plastic we would consider "ordinary." This material is the cause of the "break in" effect. It takes between 30 and 120 MINUTES to break in and you can hear the effect quite easily.  A friend with Martin Logan electrostats says they are the best cables he has ever used. At $65 for 100 feet, you can't go wrong. Surplus outits sell the stuff. I think Amazon lists it too. "Look for 50 conductor flat cable."

Thank you for that explanation of your history with the AR160 amplifiers, that is very interesting. You have a great dealer.

Truth be told it would be great to hear your system.  Of course the fact I live in Vermont puts the dampers on that idea.

Have a great day/night.

😊👍 Thanks. I have an in incredible dealer. 
 

If you ever get out this way, give me a holler. Would be great to have you over.

Would be really interesting to make a recording of a new piece of gear on day 1 and then after 400 hours.
