100+ Head-Fier
Now I regret not having believed NwAvGuy’s word that ‘if a brand doesn’t provide a measurement, it gonna measures bad’ or something like this. Should have bought an O2.
Hard to tell from way over here....but not likely. Output Z along isn't usually a distortion cause, more like a symptom.
Well I have some issues with my amp now.
I have got a new desktop DAC/amp from Yulong Audio. The manufacturer provided many measurements regarding THD (without specified loads except for power output) but doesn’t state the Z out nor would they reply my emails, so I bought the DAC/amp blindfolded. After getting it I found out it has serious bass boom and treble roll-off on my 250Ohm DT880 that’s not present in any zero-ohm source. I then tried to contact every email I could find on the internet and finally one from YA replied me and said Z out is 10< ohm.
Should this be the reason for the distortion I’m experiencing?
Again, not likely just output Z that's the problem.I think Yulong is really not fair to provide critical information of their products. And now that even my 250Ohm Beyer suffers a lot from its Z out, I’m very excited to try it with lower impedance headphones (I’m getting k7XX tmr, note that K7xx has overall smoother impedance and phase measurement).
Yes, but I'm out of time right now. If nobody else replies I'll be back later.And also I want to properly measure the Z out, anyone here has done it before? Attached is photo of my amp’s headphone output circuitry
I have two, and a couple of stories. Got to run now, but let me know what the source device is when you get a chance.Now I regret not having believed NwAvGuy’s word that ‘if a brand doesn’t provide a measurement, it gonna measures bad’ or something like this. Should have bought an O2.
Source? I don't think my source plays a role here since It's a DAC/Amp so I just feed digital signal from computer or DAP into it via USB, Opt, etc.I have two, and a couple of stories. Got to run now, but let me know what the source device is when you get a chance.
The reason I asked what the source was is because I tested my O2 for an audible difference as compared (ABX) to my DAP, and there was no difference. That's because my DAP already could easily drive my headphones.Source?

Now I have to go too, it's 4.27AM here. Thanks for your insight anyway.

The effect of a headphone amp, and therefore its necessity, is determined by the application. If your source already drives your headphones well an amp won't change anything.
I've always identified this a being old. that moment when novelty alone doesn't make anything and everything a worthwhile experience anymore, like how babies are amazed by anything new. and we instead would rather spend a good time with something we know and enjoy.I've decided to quit streaming music for a little while. I know this probably goes without saying, and hopelessly redundant, but I really like the music I own. I chose it. It is my music. Spotify thinks it understands my taste, but it really doesn't. I keep hearing the same things suggested to me over and over on these music services. Ironically enough, there's more variation in my own collection. Maybe I'm just soured on streaming for a bit. It'll probably change next month when there's an album I need access to.

I was old at a fairly young age when it comes to music. almost never listened to the radio and totally stopped when it became filled with ads. I loved stuff like Pandora for a few years as a way to find stuff similar to what I already liked(which in itself was already a sign). and now if I was told I'd have to only listen to my ripped library until I die, I'd be very fine with that.
I have a few buddies who try 10, maybe 20 new albums every week. they're fully into the idea that there are so many gems waiting to be experienced that it would be a waste to spend too much time on stuff we already know. the fun thing is, I totally understand. I was young too once.
I'm still young when it comes to books and manga. but even there, I've started to enjoy revisiting something I read a few years back. time is relative to hobbies but it still does pass(yeah that's what Einstein meant all along, the more you know). ^_^
I have the opposite problem. My library is at the point where I already have all the "regular suspects". I want to hear new things that can start me off down a new branch. I had XM radio for a while and even though it had a gazillion channels all curated by knowledgable folks, I found that it was basically a "greatest hits" selection off of my own library. I didn't discover anything new. At my level of collecting, no algorithm is going to know which dusty corner I should be rooting about it. I have to do that myself. It costs a little more because I have to buy physical media put out by small independent labels and rip it myself, but at least I'm not hearing Patsy Cline's "I Fall To Pieces" and Chuck Berry's "Johnny B Good" for the millionth time. It's amazing how much great stuff there is that nobody knows about. But after you've exhausted the greatest hits, you have to dig for it.
