post #1276 of 3032

Maybe I'll have better luck with DSD tracks.  I'll try it out.  I'm not completely convinced of burn-in, but I will put it in the oven for awhile and see what happens.  

post #1277 of 3032

I have commented on my take of the X5 in it's thread as well. I just didn't try to lobby the DX90 to happy X5 owners or convince them that my opinion was more correct. I comment and move on. I trust certain reviewers more than others but my opinions are my own. The exchanges of gear and opinion I've had with them have always been pleasurable. 

 

When questions are asked, or suggestions made, it's to try and find common ground or reasons for the differing opinion. It's not uncommon even among professional reviewers. It's not a challenge nor needs to be entertained. It also doesn't need to be scoffed at or have ones integrity questioned.

The NT-6 has an upward slope starting at the mid bass all the way past 20Hz based on the 2 graphs posted and you complain you hear more bass on DX90 than X5 and concluded DX90 is U shape and take X5 neutral?

 

For DAPs to be neutral it has to be horizontally flat end to end so it let you hear the exact sound of the music and how it gets interpreted by the phone you use.

 

It seems like X5 rolls off starting at the mid bass and same goes high end if you hear NT-6 sound neutral. So to me your impression doesn't matches the FR curve of the NT-6 you and @goodvibes posted.

Show me a more neutral iem graph and show me where X5 rolls off, and DX90 is U shaped from what I'm hearing.  And you have the Roxannes... 90 probably complements it.

You started calling a U shape signature on DX90 without showing a graph for it.

 

Just for reference look up for the FR curves of Beyerdynamic T1 and DT250 since they are available in golden ears and I have both. The T1 even with slight mid bass hump, shallow and gradual roll doesn't sound like having bloated bass. It rather sound well extended and I can feel the slam of the sub-bass on DX90. Switching to DT250 I can immediately notice the decrease in bass extension and bass quantity overall which perfectly mirrors the FR curve of both phones. 

 

That tells me DX90 is flat or at least very close to flat and doesn't roll off the edges of 20Hz to 20K

 

DT250 is as neutral as headphones can get. Tried it in both HO and LO.

Actually, it isn't bad with my CK-10.  It complements it.  CK-10 has mids are a bit forward, and it's bass light. The highs on the CK-10 can get overly bright though, but detail retrieval is great.  But, I do think that X5 has more details.

Personally, I find different IEMS will pair better with different daps...  Just because you find that your NT-6 do not pair well with the DX90 does not mean it is a bad DAP with bloated sub bass .  In fact my favourite combination for portable use is my DX90>Pico Power>Dita Answers.  Followed very closely by my X5>Pico Slim>SE-846 with Headphone Lounge Silver Cable, as the silver cable seems to firm up the bass on the 846 as well as add some airiness and openness to the soundstage. Most people who have tried the HL silver cable say it improves drastically improves the sound of the 846. However, I find the 846 with the silver cable, when paired with the DX90 sounds hollow to me, something is missing, either sub or midd bass, to me the stock cable sounds better but I still much prefer the X5 combo.  Who knows though, some people might prefer the DX90>846 with silver cable...That's their choice and preference. 

 

I do not find the DX90 pairs well with everything, nor do I find the X5 pairs well with all my headphone or iem's either.  

 

Just to be clear, I still prefer my home setup with the HE-500's over my portables....My preference.

 

 After listening again to both the X5 and DX90 I do find the DX90 to have more sub bass, I also do not find it to be out of place or unnatural sounding.   I find the X5 to have a warmer presentation with more mid bass presence and more treble rolloff.  This is how I hear it, but that doesn't mean if I listen again I might not hear it a little differently.  

 

So your decision to return it is probably the best decision for you:)  I'm keeping both the X5 and DX90 as I like each of them for their differences. 

post #1283 of 3032

Yup, in the end it's preferences.  To my ears, X5 excels, in addition to the specs(more power, voltage), and just found out the LO is very clean also. I'm doing comparison with multiple sources, and will decide if I want to keep one or not.  For portable wise, it's the X5.  I want the most neutral sounding with great details and clarity.  I don't want to keep 5 DAP with different FR. lol.  I will getting the DX100 soon, and will see how that one fares.

I think the lower treble and midbass emphasis of the X5 is simply masking it's extremes a bit where the DX90 has a more even perspective. I could see the lower treble giving the impression of more detail but to me, it actually takes away from the finer aspects of some music, especially some of the acoustic master recordings I have. Again, I'm sure interfacing and source material will vary those results for others.

Lol. I don't want 5 different daps either. The reason I have 2 is that I work out of town for 2 weeks on and 1 week off and have to stay in camp when out of town. I have to change camp rooms every set of days off so I was looking for a lighter combination. I was using the Concero HP with Pico Power to my Alpha dogs. It was alright, but my Alpha dogs pair a lot better with my BHA-1, plus it was a heavy combination to bring back and forth with everything else. I use the X5 with Pico Slim and W40 or SE-846 on the bus to and from work everyday and on the flights to and from home. I find they pair very well together as the X5 line out is very good.
The DX90 with Ditas/Heaven VI/FX850(if they still end up getting to me) and Pico power will replace the Conerco and Alpha dogs, plus I find while this setup is not only more portable and lighter, it also sounds better to me and I can get more variety.

I just got the Concero HP, it sounds smooth to me.  If it had a LO, I would try it, but since the HP out is so smooth, I don't see a point.  I'm pretty disappointed with it given it's cost.

Each has bumps none of them are perfect, so no clear winner.

I feel the same about the DX90 having a more even perspective, I feel the highs are slightly rolled off with the X5's HO and midbass emphasis as well as .  This is probably why I find the SE846 with the silver cable really shines. Since the 846 has a lot of subbass to begin with, the silver cable helps firm up the bass and add a little sparkle up top while the X5's mid bass warmth make it a great combo imo.   Also I find the X5LO>Pico Slim adds to either my W40 or SE-846.  

 

To me the DX90 has an airier, more open presentation which I find really enjoyable for detailed listening.

I'm probably going to sell my Concero HP.  I do find it is an improvement over the HP on my Macbook, but I find the DX90 performs better IMO.  I know it was double amping but I just used the HP headphone out to Pico Power for the Alpha Dogs as I found they needed more power being Planners.

I recieved this question from a fellow HiFi'er and thought I would share my response with the rest of you to see if there was anything anyone wanted to add.

 

"Hi, im an owner of a Ibasso DX90 and im looking to upgrade my heaphones. Im deciding between the Heir 5.0 and W4 and i saw you hve both paired with the DX90...

 

Could you tell me about which one pairs better with the Ibasso? Im lookin for a smooth signature with great bass and good separation and sounstage in order to hear indie rock, electropop, R&B and dubstep

 

Many Thanks in advance"

Sorry for the delay in getting back to you. I have spent the last few days switching back and forth between the two.

 

In short I think they both pair very well with the DX90.

Both have great separation and soundstage (perhaps the 4r is marginally ahead in this area). But the 5.0 blows the 4r out of the water when it comes to bass and is fantastic with rock and I imagine dubstep.

 

Put it this way, when I go away for the weekend I take the 5.0, the 4r's stay at home, however they do complement each other nicely.

 

One cautionary note, Heir seems to have dropped the ball a in terms of quality control. I had to send my headphones back due to a faulty cable, and when I got them back they sent the wrong cable. I had paid extra for the 5.0+ and it took numerous emails for them to resolve the situation.

 

My understanding is the Noble Audio 5 is essentially the same IEM, but with perhaps better customer service,

 

Then again if you are worried about after sales support Westone is always going to be the winner.

 

Good luck and let me know how you get on
