Cheers,

I wasn't sure if it moved the png to some internal filing and replaced the default.

Thanks again.

If you are talking rev 1 or 1.1 dfly I thought it was known to run a 9023.

How do I get tags if mp3tag cant find them? The tags are on the computer and play fine from there just not on the dx90.

It sounds like you are experiencing the media scan bug.  Check the DX90 bug thread for details or to include your experiences.

Yeah, mine is v1 and it is very likely that it has an ESS 9023.  However, as far as I know, that no one came out and prove it 100%.

Hm...I got mine from them...No charger. Anyway, I just got this interesting e-mail from Ibasso:

I decided to ask for a full refund since I intended to sell this when I got my unit back from ProStudio Sound and Music. I will report back here as to whether they honor the warranty and refund my full purchase price. They said something about a restocking fee, but they will need to replace my unit with a new one anyways, so it does not seem right to charge me a restocking fee.

Driver ready = driver ready + 10 days

That's the formula. biggrin.gif

I have tested the HE-500 driven just by the DX90. I don’t remember if was Jamato who said an statement similar to that what I’m gonna say.

 

The HE-500 sounds good just driven by the DX90, mind you, sounds better when they’re amplified with the emotiva mini. By the way my HE-500 didn’t come with a plug 3.5 and an adaptor 6.35, it came with a plug 6.35 so I had to buy an adaptor.

 

I also have been listening the DX90 with the Etymotic 4PT and with the Westone 4r. I like more the combination of the Etys with the DX90. The Weston sounds really good but I prefer the sound of the Etys.

I think it were my findings with the HE-500 you mention. Also the Tzar350 is a good mate to the DX90

I think they forgot to pack yours, as the charger is just in the USPS bag and not part of the official packaging.  Here is everything that I got from ProStudio:

 

 

 

This is exactly what I received from them (received this past Tuesday)

Ok this is becoming a sound science topic but is a very basic one. V, I, R are all involve but you only need to get 2 values of any combination of the 3 to compute for power. These are not absolute values because there are other factors involve (e.g. cuurent limiter circuit etc) but the headphone sensitivity/efficient spec are nominal values and they are good enough as a general guide.

To make things simple:

96dbSPL/mW headphone definitely will play louder than a 97 dbSPL/V all things equal. If you don't agree the best thing to prove it is get the 2 exact headphones in question K545 and DT880 and see which one sounds louder.

 

Just quickly did some calculations using an excel sheet from http://www.apexhifi.com/specs.html

 

Please correct me if my maths/use of specifications are wrong (DT880 600ohm + DX90 on High gain)

 

 

Seems like at maximum power from DX90, we can acheive 107dBSPL on the DT880 600ohm?

Hi guys! Just wanted to ask, how long does your dx90 battery last per full charge? Thanks!

Speaking of the user replaceable battery, how the hell can you guys take the back plate off?  I tried for over 10 mins but I gave up.
