To illustrate, a 1x gain at 2vrms of input will sound louder than a 2x gain at 0.75Vrms of input.

Gain alone will not tell you how loud the volume will be or if the amp can properly drive a phone. You need the input level and max power the amp can supply given a specific load in ohms.

An amp may have plenty of power for a given phone. But if gain is not properly match, the headphone will sound underpowered or may clip.

But it's always true that higher gain has higher noise. Digital volume works best at higher volume level and analog pots are prone to channel imbalance at very low volume setting. Which in all cases you want to avoid a higher gain if possible.


Okay, let me see if I understand you correctly (because I'm only on page 533 of this thread in real-time). Let's say I have my DX90 set on low gain, and I'm using the volume of my DX90 to raise the volume.  It's not going to drive the HD800s.  But if I use my external amp (on low gain) with my DX90 on low gain, as described above, and I'm using the volume on both devices to hit a comfortable volume level, then in theory, somewhere in the middle I should hit the sweet spot, without adding any extraneous noise, yes?  That is to say, I've kept the noise level very low on both devices, but achieved sufficient volume to drive the cans, assuming my amp is up to the task.  Is this correct?

 

But hey, so far I've only updated the FW to Lurker's latest version; and my DX90 is sitting - out of my line of sight - with burn in sounds going through it for the next few days before I can even reach the listening point.

 

In the meantime I think I'll ruminate on what to load up in the DX90, first.  I'm thinking Neil Young's "After the Gold Rush," Metallica's "Master of Puppets" (Steve Hoffman's master), Pink Floyd's "The Final Cut," aaaaand...wow, I need some hi rez in there. Duh! Jimi Hendrix "Electric Ladyland" 23/96 vinyl rip, Yes "Tales of Topographic Oceans" DSD, for trying it out as a desktop DAC.  Sorry.  Just riffing off ideas of well recorded albums. :L3000:

If you are using an external amp with DX90, gain should not matter. You must be using the Line Out and should be bypassing the internal amp altogether. Also you stilll need to set the volume to max level.

yes for 100%

Hey guys.

 

I'm strongly considering grabbing the DX90 for $359 off Amazon. I just have a few questions please.

 

I use my DAP's as a shuffle basically. It's in my pocket, I press the next track and/or volume buttons through my jeans and use them exclusively with my SE846 IEM's (9ohm). As such, I really dig the low impedance of this player. The battery life shouldn't be an issue. 

 

1. Are the volume and play/pause/next buttons easy to feel through jeans? Do they stick out enough? Do they give a good tactile feel when pressed or are they mushy?

2. Are said buttons responsive? Say if I'm pressing next-next-next is it responsive? Any lag from the physical buttons?

3. Does the unit heat up during use? 

 

Thank you kindly!


1. They don't stick much but they feel good when pressed.

2. Yes, a little lag but perfectly usable.  

3. Yes, but not a problem in my opinion. 

 

 

Can we expect iBasso to add in line remote control support for the DX90 (350$)? I would love to use my amperior remote with the DX90. Fiio have just implemented it on the X1 (99$):

 

【FiiO X1】FW1.1 introduces new features and improvements for X1     
 

1.Added support for M3U playlists and internal playlists.
2.Added setting to enable / disable use of in-line remotes on earphones.
3.Enabled playback of songs with sample rate under 32kHz.

Using the remote requires a trrs plug as opposed to a trs plug and additional wireing, not just fw changes so I wouldn't expect that to ever be supported on the DX90 but perhaps on a future dap though I highly doubt it

I would personally find it very useful. I don't understand why is not a standard feature in a DAP, specially a high end one.

^ well majority of headphones and iems don't have an inline volume control anyway, so only a minority of people would benefit, also inline volume/mic can sometimes degrade quality of the signal, which is why you don't find them on most audiophile headphones and iems. Also having a TRS jack instead of a TRRS jack has its own minor benefits in durability and compatibility, so there isn't really a huge argument to implement inline volume control. I find it really easy to change the volume through my pants pocket thanks to the nice button placement of the DX90, I bet after a while you will get use to doing this and it will become a non-issue.

Does anyone have an opinion on this? :)

DX50 is fine in this case.

Does somebody know whaqt the best media player for accurately syncing sound? I can sync my DX90 but not accurately

Well, we'll see how the DX90 handles my HD800s. I have a feeling I'll be in the market for a new amp, depending on how my old one sounds...or, just because I want one. Still about 380 hours of burn in to go, so I'll give a rundown around Dec 15th. Wheew!

Wow you have a lot of patience. The first thing I do when I get a new toy is use it. I can't even wait for my tube amps to warm up lol

Not sure.  Have you tried the AK120 or 240?

Ha! No, I don't have a lot of patience. It's just that I have a lot going on right now, so I might as well wait to get the right impression of the DX90. For what it's worth I listened to about 3 minutes of brown noise through my HD800s. Ha!
