It's claimed that an Ayre KX-5 Twenty requires a 500 hour break-in to sound its best. Can it be that each input requires that break-in?
As other have said, it may get better with age and only the phono stage would be an input that would need additional break in as far as inputs. But if neither isn't amazing out of the box, why bother?
I'd love to try one out and wish I could afford it.
What do you think? Have you had it in your system?
I don't expect delivery for at least several weeks. I'm using a K-5xeMP I bought used that I think sounds pretty damn good. Users and reviewers claim the KX-5 Twenty sounds substantially better. I don't think Ayre implies the sound of the new preamp will be bad, just that it will take a few hundred hours to reach its sonic potential given the nature of the materials used in its construction. In addition to the C-5xeMP, sources will an Oppo 205 that passes DirecTV, Fire TV, and Apple TV, and a Sony HAP-Z1ES. Watching TV can put on a lot of hours and the Sony can play in repeat mode.
The preamp has no phono stage. In another setup I use a Parasound JC 3 phono stage with a JC 2 BP preamp and JC 1 monoblocks for vinyl.
IF it does Not have a phono !
Then a 40$ Passdiy.com B1 buffer kit ..WILL.. outperform it.
Without any doubt whatsoever.
Audio game requires 'some' situational awareness my friend.
bare, your posts have been nonsensical and unhelpful. What's the problem?
I concur w/ airtime. Yes, several hundred hours are required for break-in/burn-in. I fully support this theory. Bring a fan of Conrad Johnson and that company's teflon caps/parts, I can testify that 500 hours, is the bare minimum.
For every device someone has some other giant killer THEY think is way better.
Freedom of choice.
I have grown so tired of this tired topic. Capacitors in particular need burn in- the sound through capacitors goes from muddy to good to muddy to excellent over many hours. There is NO ONE who knows more about audio technology than Charles Hansen so chuckle and tease all you want- it only reflects badly on you.
But if it sounds bad out of the box, send it back. Your brain will adjust to the sound over time.
If it sounds good out of the box and gets even better, that's OK with me, but there's at least a chance that the brain will be slow to react to the improvement...500 hrs?
But that is enough reason for me to despise the endless claims about break in.
It may be true...
But it may also just be a steaming pile!
So I would advise anyone who gets the run around about break in (if they do not like a component's sound) to be VERY suspicious.
And never let some seller/ salesperson talk you into hanging on to some POS while they are spouting about break in.
Really the ideal item would 'sound pretty good' out of the box. Then, as break in proceeded the sound would improve to 'stunning'.
Stuff which still sound like crap after 48 hours IS CRAP. PERIOD.
I'm usually looking to hear "potential" early in the break-in process. If 48 hrs. pass and I don't hear a hint of magic, probably made a bad choice. Morrow cables ( IC's in this case) were a good example of this. Despite the insane claim of 500 hours break-in needed, I heard a bit of magic after only about 12 hours. Stuck with it and they only got better. And yes, I believe some of the "required" break-in claims of hundreds of hours can be somewhat of a scam to get the inexperienced to accept what they're hearing being better. Now to be fair, I have a friend who is constantly trying different designer caps in both his pre-amp and power amp looking for that "magic" cap or caps. Seems like he's spend months doing nothing but breaking in caps. Some have notoriously long and painful break-in periods. I use him as a classic example of the road I DON'T care to go down in this hobby.
Important thing to consider is take careful notes during those 500 hours of break in so that you can hear the micro differences in caps breaking in. Best to listen to pink noise for at least 100 of those hours.
Ayre claims a 100 to 500 hour break-in, but doesn't specify whether that's total or for each input. Presumably those numbers come from Charles Hansen, the designer. I'm buying the KX-5 Twenty preamp to replace a K-5xeMP. The KX-5 Twenty is designed to match my KV-5 Twenty amp, and should pair well with my beloved C-5xeMP disc player.
" Ayre claims a 100 to 500 hour break-in, but doesn't specify whether that's total or for each input."
That's obviously what I should do if I need an answer. In retrospect, though, it is what it is. And when the KX-5 Twenty arrives I'll install it and begin to listen. I can turn the level way down, set the Sony HAP-Z1ES to repeat all tracks, and let it run while we sleep -- might even be able to set the KX-5 Twenty to standby. During the day, it can provide audio for TV, with only occasional bouts of music.
Sorry I wasted everyones' time with a poorly thought-out query.
Guess it depends on whether you listen to Coltrane or Desmond, Steely Dan or Queen, Haydn or Ligeti, Jay Z or Luther Vandross, Nancy Wilson or Aretha.
It doesn't matter which input you use. The main break in they are talking about is the signal caps/path and power supply parts. The input is simply a selector switch feeding the signal TOO those parts.
The only exception is phono input. All the others are electrically the same.
I am going to contradict myself and say this. I did find that teflon caps are an exception and do take a LONG time to break in. Mine took about a years in my CJ preamp and the sound did change a little.
I rarely agree with bare but 500 hours - come on!
Saying 500 hours is just asking you to keep the stereo until you just accept it's sound.
My personal opinion, and we all know how much that's worth!, is electronics break in in a hour or so. Charge up the caps, settle in some solder joints and you're good to go.
Open to buying a bridge too?
There is no breakin on solid state,
other than in the minds of Marketers and the Gullible.
But then we all hear what we to want to hear.. in ALL things.
Ain't humans wunnerful?
Good question, as long as all the "line in" sources are the same (CD/Tuner/AUX) it should be ok. But if you have a Phono section, that's a separate circuit. all the others use the same circuit but have a switch to select between them.
