Just received my DX90 and very, very impressed with the fit, finish and sound, even out of the box before burn-in. I do note that the EQ produces substantial volume boost even when set flat on all frequencies... does it introduce any distortion or loss of fidelity to leave it on and flat or is it better to set it to off and raise the volume on the player (or in my case, ifi iDSD dac / amp)? Thoughts, opinions welcomed. Thanks!

Exactly opposite: EQ produces volume loss when it is turned ON. The label "On" in the left bottom corner means "Tap me to turn EQ On", and the EQ is off when it is visible. It is the action, not the state.

CL Duet ^

+1. That's what comes to mind immediately for me, especially if you can go balanced. You can also consider the ALO audio MK3B, which has a bit more power behind them, but to me, the Duet is a bit cleaner.

Both are great choices though!

+2 on the Duet!! It is a wonderful portable amp. I find it to be more powerful to the ALO RX though

Was thinking also for the CL Duet to pair with the DX90.. Do you guys think the duet can power the Alpha Dogs too to its best, or close to best? (Alpha prime soon)

From what I know, turning on EQ means it's no longer Bit Perfect

Ah, don't I feel stupid. Thank you for clarifying....much appreciated.

No need to. I don't get the logic either! APPLY or TURN OFF would be without confusion.

Need actual listening opinion between DX90 & DX50.
Does DX90 sound significant better than DX50 in term of soundstage, separation, clarity and bass?

@boombobby289
 
definitely significantly better in terms of soundstage, separation and clarity. i'm not a bass person so didn't pay attention to that. I upgraded from a dx50 to dx90 because I made the mistake of auditioning the dx90. couldn't stop thinking about the sound impression after that. I feel that the price difference is justified. hope this helps

DX90 also has more extended bass than DX50, my DX50 could never reach down as low into sub bass as my DX90 can.

what firmware are you guys using? mine came with 2.1 and i am not getting as much bass as i had with dx50. i've read that firmware 2.0 is a more preferred version. I am not sure, or maybe i should upgrade my IEMs too after upgrading my source.

 

[T.R.A.N.C.E.]

Most people using lurker modded 2.1 firmware, its linked on page 1 of the thread, it does increase bass a bit over stock 2.1. But what iems you using?

How much time do you have on the 90? It takes at least 150 hours of burn in for the bass to be well defined and more powerful. I would use the supplied burn in cable and just hit repeat.

+1
 
And don't forget the brain burn
 
DX90 has a lot of treble extend, so I was focusing only on treble / high-medium the first two weeks (not intentionally) . It's sound a lot more balanced now. I can't really say if it is hardware or brain burning effect (I have not a new device for testing), but I don't really care ^_^' .

after almost another day of burn in (burn in cable and continuous use), i am finding my dx90 better sounding than before. 
 
and now that you mentioned brain burn, i am not sure if the player sounds better or my taste is just starting to shift as i appreciate its sq more now - after continuous use. what is important is i am enjoying.
