Thread Starter 

I have a Mac. It would be nice but even though I have a huge storage and can use it with other daps or from the Mac to the Hugo, I don't . I find I get all the music I want by using the DX90 storage out to whatever I am using it for the Hugo or line out to something else or just the DX90.

Here's a theoretical question - is there a real advantage in having 2 DAC chips, given that there is no balanced output on the DX90? Obviously there's no DX90 with only 1 DAC chip that we can compare this with, but I was wondering if the dual DAC thing makes any actual difference in an unbalanced setup.

I'm using DX90 with Westone W60 and its phenomenal peoples :D

How many of you guys actually use the DX90 as a DAC for your desktop/laptop? I'm trying to convince myself I don't need it. lol

I never used it as a desktop DAC. Even when I had just the E18, I might have used it as a desktop dac/amp just twice. I do not like being tied to a desk, while listening.

I alwaya connect the dx90 with my lyr2 listening to the he560. So far im still happy with that setup.

Although I would like to use it, it's pretty much unusable with 64 bit Windows at the moment, due to the missing signature.

If I want to listen to something from my PC, I simply connect the DX90 and copy it over in a matter of seconds.

It Improves the signal to noise ratio, distortion and should be better in other dynamic aspects as well. Helps with a few things like the v control and low level retrieval. Many still don't know this but as opposed to analog, distortion in digital goes up as signal level goes down. It's often neglected by those that are standard def proponents. The subtleties like ambience decay, inflection and other subtleties have more distortion than the loud portions where in analog, it gets somewhat masked. The type of distortion also comes into play as does being able to hear into or track into a noise floor. Here's a friendly read from Benchmark. http://forum.benchmarkmedia.com/discuss/feedback/newsletter/2010/08/1/unique-evils-digital-audio-and-how-defeat-them How much is audible will always be debatable and if there, will also obviously be affected by associated kit and files.

 

 A balanced signal gets summed (differentially compared) somewhere even if it's not until the transducer. The digital advantages remain regardless of where done, next stage or at the end of the chain.

As a complete and utter newbie running a DX90 with UE 900's could someone answer me the following question with a simple yes or no please?:

 

Will I benefit from updating the firmware to Lurkers version?

 

Having read all that came before I'm pretty certain the answer is yes but then someone got all technical on my a*s and I lost the ability to think straight.

:L3000:

 

Thanks in advance

Tim

Are you currently using 2.1 or 2.0?
post #7542 of 8552

2.0, haven't changed anything (except adding a nice wallpaper :o)

I see okay, for some including me, the bass of UE900 does not dig deep enough nor is it tight enough. Thats my preference comparing to my ckrs. The main difference between your current one and lurkers fw I'd say is bass, although like i have been saying I have noticed slightly more clearer mids n slightly better details on lurkers fw. So it really depends on you, want slightly clearer sound and better detailed mids and highs at the expense of abit amount of bass then up, but if the songs you listen to normally requires more bass for enjoyment then stick with 2.0 because bass has lower quantity on 2.1 though its abit tighter, still does not satisfy me. You can always try them both and see how they do for you as you can always go back to 2.0 :P

To me, that's only true when there are limitations elsewhere in the chain but when all is right, IMO, 24 bit is rather easily blind tested and preferred. I think 'proper testing' is the issue here. I'm not debating that usb DACs or most DAPs limit this but rather that format evaluations should only be done with a premium chain. If you can pick 24/96 or better over Redbook 10 times out of 10 on a simple, well chosen under $15k 2 ch setup (where speakers are the least expensive component) it's probably not the bitrate that is limiting things in most comparisons. If you want to say that it's not a big deal with DAPs or PC audio, I may still disagree to an extent but can understand the sentiment. I think we need to be more careful with these universal truths. How often have we heard, "I didn't believe in (breakin, cables, bitrate, etc) but then I heard.... I don't see the high def vs redbook issue any different than the 320 cbr vs Redbook issue. Depends a lot on the quality of the files and what you play them through.

 



Just to make the argument simple and relevant to this thread. Let's say it's the same source file mastered and distributed in 24-bit hi res fomat. downsample the same file to 16-bit. Then only DX90 and any phone of choice for comparison. smily_headphones1.gif

I've sent mine away for a bit and will try with files I know well in a few weeks when it returns. I had no problem doing so on my AK120 when I had it so I don't expect to have much trouble here. I could even pic out dithers used tor render a particular HiDef recording. Could be that I use files that I or my associate recorded either live or from other good sources onto a Nagra VI. Any adjustment or resampling is done via Wavelab pro. I think that for simple downsampling, DBpoweramp or XLD work well for consumers. Many of the HiRes downloads available for purchase aren't as good as I'd hope. Others are. Same can be said for a lot of the A2Ds and how they are used. I get that storage and usage may render HiDef unnecessary for many in a DAP but I wanted to state my contrasting view on formats in general. I'd be fine if whether HiDef is better or not just be avoided completely in equipment threads.:smile: Perhaps it's warranted in a HiDef player thread.

I would like to use it as a DAC at work, being I have my hdd with all my music here, then I can just listen to that.  Currently I use a dragonfly > RSA Shadow, but I would really like to use the DX90.  Same as above, however, waiting on a useable 64bit driver for it.
