CD Player break in period

I will be very interested to hear what others report. I just unboxed my X-03SE and, once my speakers arrive, the listening will begin. I have to say that I find your experience perplexing. I do not dispute that equipment will improve in sound as it is "run in". In my experience some equipment, loudspeakers for example, require more break in time than other components. However, the number of hours you report seems VERY extreme, as does the really poor reported performance of the unit during the early break in stage. Although I may end up eating my words once I get mine fired up, it seems to me that 5-10 hours should bring any component (other than speakers) to around 90-95% of its performance capability. The last 5-10% occurs gradually over time and is sonically pretty indistinguishable from what is achieved in the first 5-10 hours. I've found this to be the case with wire as well as electronics (again, not speakers, whose dynamic drivers do require some limbering up). I hate to suggest this but if I were in your shoes I would be investigating whether your machine may have been damaged during shipping, perhaps due to exposure. Your dealers claim doesn't really mean too much since he has little interest in disabusing you of the notion that the player needs more break in time to reach its potential. I may get bashed here but I have to say that if, after 500 hours, the player doesn't sound right there is either something wrong with it or there is a problem elsewhere in the signal chain. I'll report back after I get mine up and running and if I end up experiencing something similar I'll fess up and take my lumps.

I'm trying to keep an open mind here but I'm really having difficulty believing that a $7K cd player can sound "unbearable" regardless of how many hours of break in. These kind of statements simply baffle me. In my experience, break in results in a subtle change in the sound that a lay person would never even notice. When those of us who have been at this for a while and know our systems well put on our "analytical ears" we can discern these subtle changes. Again, I could be wrong since I have not had a chance to hear my player yet but if mine sounds "unbearable" with the first CD it is going back to the dealer. I have another concern--that people unwittingly use break in time to grow accustom to bad sounding equipment. They want to believe the piece they bought sounds good and so over time it begins to but instead their ears just get used to the sound they are hearing (which they accept) rather than the sound of the equipment actually improving. This is why I have a rule when I demo speakers--I listen to about 30 seconds of a very familiar cut. If it sounds "wrong", I'm done. (Sometimes I will then listen for another half hour or so just to try and learn something). If it sounds "right" I settle in for an extended session of analytical listening. If I don't do this what can happen is I start convincing myself that the speaker that sounds "wrong" may actually sound better than I originally thought. In other words, my ears begin to adjust to the sound and it becomes more acceptable.

This discussion prompted me to contact the dealer I bought my X-03SE from and get his take. He said that while there is considerable difference of opinion on break in of components his own views tend to square with what Cerrot and a few others have said here--namely, that the Esoteric's require quite a bit of run in time. Cerrot, I looked at the website after reading your post and did see the reference to 250 hours. I have sent Esoteric an email requesting clarification on whether double or triple that amount of time is necessary or not. According to my dealer, the Esoteric's will reach 90-95% of their potential after around 750 hours. Again, Cerrot, very much in line with your experience. He did not state, however, that the machine sounds as bad as you report during the break in phase. Additionally, I have decided to pass up a learning opportunity and have now begun breaking in my machine while waiting for my speakers to arrive. I had considered leaving the machine unused until I could listen and then reporting back to the thread with any changes in the sound at various break in points (100, 250, 500, etc). But, listening to everyone's experience here and then having it confirmed by my dealer, I decided to forgo the learning opportunity and just get on with burning in the player. I've been without music for five freaking months--the last thing I want to do is have to wait another two weeks while my player reaches it's peak potential. So, I concede the argument that Cerrot never wanted to have by giving up the opportunity to inject evidence from my own experience breaking in this machine. Finally, on the question of how to break the player in, my dealer suggest I put the Esoteric on "repeat" mode and run it into my preamp while it is turned on. Just a slight twist on what was reported here--that the preamp should be on while the player is doing its thing.

Not sure if it matters but I've got the preamp on "mute" with no output. My amp is "off" since the speaker leads are lying on the floor waiting for my new speakers and I wouldn't want power to get to the wires risking a short. Do you think I am getting the break in benefits with the preamp muted?

John:

I'm interested in a response to your question as well since I am using up tube life to burn in my cd player. If I can get away with the preamp off and still get the job done that would be my preference.

I've now heard back from two people who I contacted regarding this question. My dealer instructed me to turn the preamp "on" while breaking in the Esoteric, and so I have for the last 30 hours. Tonight I heard from Esoteric Tech Support. According to these folks no other equipment needs to be connected to the player during break in. Since this is the easier answer for me to accept, I've turned off my pre and will break in the rest of the way solo. I'm not sure what accounts for the discrepancy here--probably nobody really knows for sure whether having the player connected to a live preamp makes a difference. I'm inclined to think that the bulk of the internal components get broken in without a live preamp but perhaps there are some parts related to the output stage that would benefit from a live playmate. Despite this, I'm going to leave the preamp "off" and hope for the best--I'm really not keen on burning up tube life to get the last little bit of break in that might come with a live preamp.

I thought I'd get back to everyone with an update on the break in of my X-03SE. While waiting for my speakers to arrive and break in I managed to put about one hundred hours on the unit in a "passive" break in mode--i.e. with the player spinning a disc solo on repeat mode. Once my speakers arrived I listened mostly to LP's so I could break them in while the cd player spun away. At the 100 hour mark I began using the Esoteric. I listened to several discs and then put the machine on repeat mode so it could break in some more. I would listen again at the next 50 hour interval to the same discs and note any perceived change in the sound. I'm now up to around 300 hours and so have listened at 100, 150, 200, 250 and 300 hours. I have to admit that there has been noticeable improvement in the sound--the player at 100 hours is not the same machine at 300 hours. What I heard at 100 hours was much more forward, etched and fatiguing than what I hear now. At three hundred hours the player has begun to relax, lay back and become more three dimensional. Inner detail has improved and the machine sounds much more musical and engaging. I have to say that at 100 hours I really did not like the Esoteric. In fact, I was thinking I had made an error in selling my Naim CDX2, which sounded much more musically satisfying by comparison. At 300 hours the player is in another league altogether. Gone is the glare and lack of tonal subtlety. The player now surpasses the Naim in musicality and adds more detail and authority in the bass. I am going to continue to burn the player in solo and listen at 50 hour intervals to see whether there are additional improvements beyond the 300 hour mark. I expect there will be, however slight. Cerrot--it seems you may have had it right on this one!

Cerrot--I agree totally. I'm now well over 300 hours and the player is really coming into its own. All of the hardness and lack of dimensionality are gone--GONE. The thing has just laid right back and now sounds liquid, three dimensional, dynamic and REAL. I have to say that if it gets any better than this I'll.....I don't know what I'll do. Right now the Esoteric bests my Scout/JMW/Dyanvector 20XM across the board--the thing is just phenomenal. I will continue to do the solo burn and see where it takes me. I'd have never thought break in could be so dramatic or so long a process. I wonder why Esoteric doesn't provide more information about break in (how long, how to, etc) in their owners manual. Or perhaps they could burn them in at the factory. Either might ease the minds of those who feel robbed when they hear the player right out of the box. John, to answer your question--no, I would not say the player sounded "unbearable" at the start. But I can certainly see how some might characterize it that way. When you lay out $7K on a CD player it really ought to sound dam good from the jump. And I will admit I too was disappointed initially. So, I guess I would say it sounded somewhat "unbearable" compared to where it is now. BTW, I'm using a Empirical Design power cable and interconnects going to an ARC SP16 and then an ARC 150.2. Speakers are the new Daedalus DA-1.1's, which are unbearably AWESOME.
