Sensitivity is not the same as impedance, I mean the dB/mW or dB/MV, thus the sound pressure generated per an amount of energy.

The RE600 delivers 102 dB/mW, while my cIEMs deliver about ~120 dB/mW. 

I actually sold the ibasso DX50 because I had quite a bit of noise when using it with the cosmic ears BA4f.
Something I now regret, because the RE600 should have little to no audible hiss with the DX50.

Output volume depends both in sensitivity and impedance when it's measured in dB SPL/power. When measured in dB SPL/voltage, it is only dependent on sensitivity.

since i have both in front of me.

 

 

the DX50 with the RE-600, his is technically detectable.  as in i could hear it but is sooooooooooooooo slight for all intents its non existent.

Alright thanks. 

 

I bought the RE-600 yesterday, it was the last pair I could find in Europe!

I will be using it mostly with the Rocoo p since I sold the DX50. Judging from your comments, the re-600 will have some hiss with the rocoo p, but it should be managable. 

When the next paycheck comes, I might purchase the DX90. I have not seen any good comparisons between the DX50 and the DX90.

Anyone here that has some more knowledge about this? 

One important question, does the DX90 have a different amp than the DX90?

I found the DAC to be quite amazing on the DX50, but the amp could be improved on slightly.

Do you think the dual sabre dacs will actually make a huge contribution to the sound? It comes across as a new novelty feature, something used to get more sales.

you know if hiss is something that really bothers you, adding additional impedance will remove it.  you have to have a reasonable amp in whatever your using to power what your using but all the things youve mentioned should be more than capable.

 

if you search round ebay for 75 ohm adapters, originality they were for etymotic ER4's.  the difference between the p and s was 75 ohms so you added it and voila, youve "upgraded" your ER4p to and ER4s.  generally speaking its an idea that holds true for all IEM's without a crossover in them. however as a side bonus is that the additional impedance will remove any hiss that your encountering.

Oh right, I forgot that that's actually a possibility with the RE-600. It barely has an impedance swing.

But, I hope I wont be using the RE-600 for long with the rocoo p. Although it has an impressive soundstage, it does this somewhat artificially.

And the sound is slightly harsh and lacks some timbre and detail. I guess I'll first want to hear how it performs with the RE-600.

well as with all things, your ear is the final and absolute arbiter of all things. :regular_smile :
