How are you liking the 600?

 

I get the 600's today, probably in about 3 to 4 hours so I'm very much looking forward to hearing them.

Make sure you give them 729 hours of burn in exactly. They'll sound like crap within the first 600 hours.

 

 

 

 

Kidding. Enjoy, and be sure to post initial impressions.

No I was going for a full 1000 hours as that's where I heard the hit their sweet spot.

LOL Enjoy going past the return window. No worries, that all translates to: 

"you have eternity to burn these in now"

A little off topic, but the whole burn in obsession amuses me.  Most things wear out over time.  Our cars get worse, our computers slow down, our microwaves become less hot, etc.  Yet, when it comes to audio, the components supposedly get better the more we run them in.  Very interesting indeed.  I don't buy much of it beyond the first few hours of a headphone and vacuum tubes.  I feel that everything else is just expectation bias.

My HD600 passed through the sort facility and will be here this afternoon so I'm pretty pump already at 7:30 in the morning.  Looking forward to comparing it the the HE-400.

Not that it necessarily applies to headphones, but cars do not "get worse" strictly speaking.

 

A brand new car goes through a break-in process where the engine actually improves over the first few thousand miles. Horsepower and fuel economy increase as the pistons and cylinder walls get to know each other, suspension components (bushings) settle in, brake pads and rotors meld, and tires get grippier as the top surface initially wears away.

 

I dont believe headphones change audibly over time (except maybe when pads compress over time and change the size/shape of the head/driver space.

This was true 50 years ago before manufacturing tolerances improved, but it's largely a myth today with modern motors.  They are now broken in at the engine assembly plants when they run them at 3000 rpm under load for a bit.  Most new cars we buy now come with motors already broken in.  The fact that owners manuals still tell us about break in is to prevent people from over-driving their new, unfamiliar cars and doing something stupid.  Or, the manual writers never talked to the assembly people.

If headphones required burn in, then it would make sense for AKG, Beyer, etc. to do the same that the auto manufacturers do and "run them...under a load for a bit"  If they sounded noticeably worse before break in, then it would be wise for them to do so....but they don't....nor do they advise the consumer to 'burn them in'. If the manufacturers don't believe in it, I'm pretty suspicious of the whole concept.....other than 'brain burn in'. Not saying it's impossible though...

Not all manufacturers do this. Ferrari does.

 

"Break in oil" is still used in many cars when they come off the assembly line. And not all cars are "broken in" at the factory. A quick dyno run or lap around a track may not be sufficient to fully seat the rings. Modern cars are definitely built to higher tolerances now, and full break in is much quicker than years ago, but it still takes place after delivery.

 

Its a contested topic, for sure (and off-topic) wink.gif

But, if someone else is driving the car, you can break in the car and your headphones at the same time!  beerchug.gif

Anyones thoughts on a Lyr 600 pairing?  I was originally thinking Asgard 2, but my budget was upped.  I know it's overkill.  I don't care.  I have a V8 in my truck.  biggrin.gif  The Canadian distributor is supposed to have these back in stock mid month.

A couple guys on the HD650 thread swear by the Lyr and HD650 pairing. Sounds like it would be worth the try... I like buying Schiit products from Audio Advisor since they have free shipping and a 30 day return policy.

My other cans are AKG Sextetts 600ohms. I'm definitely drawn to Schiit products.  They seem like such good value.  For me the best option to purchase in Canada is Headphonebar.  I skip all import duties by purchasing through them and they are the authorized dealer up here.  8.95 shipping is reasonable too.  I'm thinking the whole tube rolling idea should keep me from getting bored.  beyersmile.png

I've only had them for like 20 minutes and even without a burn-in or brain burn-in I really like the sound signature on them and the also have much more detail than I was expecting.  I'll have more impressions later so for now I'm just going to listen.
