Around a 100 hours or so for burn in. YMMV though.

I received the D4 a few days ago but have only gotten about to listening to it now. Not really experiencing an epiphany with the IE8. Sending the signal from the D4 to the Alo Rx seems to improve the overall clarity and sound stage. Am wishing for a bit more treble extension and presence. However I do have a topkit on the way to play around with. This is just out of the box so am reserving judgment until I've given it a thorough "burn in". What's the generally recommended amoumt of hours recommended for these ibasso amps?
Any ways I love the finish of the amp so much better than my Alo Rx which is just so scratch prone. Its a lot smaller than what the pics have led me to believe as well.
Anything major changed for you Larry, I found 25 hours gave me better soundstage and more detail,more as the sound opened up. I have not done more then 50 hours on them yet so I don't know what 100 hours will do for them.
I'm still new at this, so pardon if this is redundant for some of you.
I'm still waiting up on my D4 to arrive. In the mean time, I'd like to discuss some things with you fellow Head-Fi'ers. I've been living with my old Audigy 2 sound card since 2003, I believe. There's one thing I like about it which is the ability to easily EQ the bass/treble settings that apply universally to every program (music, games, movies, etc). This might not be ideal for some of you (from what I think is known as "colored). From what I understand, the D4 can't do that. I'll be honest and admit that I do up the treble and bass settings under my sound settings so that they can apply to everything.
Pretty much, the only way to change the sound signature is to switch out opamps it seems (which aren't as significantly different in the difference EQing (not from winamp/foobar but from speaker properties in Windows, a feature the Audigy 2 has).
I notice when I EQ with software such as Winamp, I get distortion. But I can safely bump up the bass/trebble settings in speaker properties (audigy2) to my liking (espically for the UE TF.10s).
I also understand that some don't even bother EQing. Honestly, with 0 EQ changes under speaker properties, I feel like it's too flat.
I received my D4 a few days ago and have been very much enjoying it paired with my MS-1's. Do any of you have recommendations for opamps? Though I'm satisfied with the sound I'm getting, I would enjoy any improvement I could get from rolling the opamp.
And I also have a noob question: when burning in, do you need to have headphones plugged in?
There's absolutely nothing wrong with using an EQ to get the desired sound you are looking for. To each his own. It's all good. I use the D4 dac and then eq individual headphones.
I recommend using Electri-Q parametric eq VST plugin for foobar2000. I've tried several so far and prefer Electri-Q.
You will need:
AiXcoustic Creations: Electri-Q - posihfopit
Put the VST Wrapper dll in the foobar components folder and add it to your Active DSPs in foobar. Then add the VST plugins folder to VST through VST setup. It takes some getting used to, but the effort is well worth it. If you really want to get down with it check out this thread:
Well for the price of the charger and the battery + shipping I can buy about 90 regular 9V batteries! Not so sure if the amp can even last that long, considering I use the DAC at home.
Cool... yea I know UM3X isn't the best for your mods, cos ur objective in modding was to accomodate the larger phones anyway!
Will the Li-Ion batt idea really not be feasible at all? Charging is really a pain.. my rechargeable batt lasts about 3-4hrs or less
