Then it's time to turn on the bluetooth
Hi
@Ryokan,
Just my two cents...
Personally & subjectively, CB 13 is still perhaps the
'best' synergy for IT 04 I have found though if you're curious, the following cables in no particularly order also pair well with IT 04 :
Penon GS 849
Penon OS 849
Penon GD 849
ISN Audio H 16 (Current Pairing)
ISN Audio C 16 (Good for Neutral Sources or if you want more Bass)
Sony IER M7 Cable
Bluetooth as a audio connection is highly subjective & personal, not to mention there is no real defined standard between BT 4 + or BT 5 + on which codecs should be used with either BT standard, for those which still only have BT 3, it is even more a crap shoot.
So aside from well recorded source quality, personally & subjectivey, LDAC and AptX or AptX HD tend to be the most consistent codecs for giving close to wired experience, especially close to a natural bass response though this will depend on BT source as well as BT cable involved.
Personally, LDAC is the only one so far which gives that good natural bass response & most consistent overall good sound, I have no access to HWA so cannot comment on that codec.
It is important to note, some smartphones & smart devices, with developer settings enabled allow for user selection of BT codec so if you use BT audio on a device with this option, ensure the highest codec available is always selected to get the best possible experience & make sure it doesn't reset itself as it may want to do.
As a final note, burn in is highly controversial for various reasons which don't really need to be gone into as no one will talk about anything else. So whether one believes in the process, what is important to note, aside from whatever perceived sonic changes there may be, components still need to be
'run in' to make sure everything works as advertised though this tends to be truer for machinery & other related gear but not exclusive to.
Just as a general statement, given the product volumes some manufacturers make, they more than likely don't have time to do that burn in.
A good analogy for burn in would just running a vehicle from day to day to ensure everything works consistently.
Or even better, say you buy a vehicle from a dealer, used or new, doesn't matter, the important thing is it works & you're covered if something goes wrong & usually there is a time frame, from a few weeks to a few months where there is either a complimentary service or a service for a nominal fee from standard to check everything works well.
Hope this makes sense.
Feel free to ask more if you need
Hope you have a great day !
