Hi everyone, its been some time but I'm back in the market for IEMs.    I have been digging around and am currently considering: UE900 Heir 4.ai W4r (I like the idea of a removable cable for longterm durability) 1964 v3s    My source will be a 15" macbook pro retina   In the...

Quote: Not saying you did, but you did ask "What is this "high frequency shift" to which you refer?" so i was just trying to answer that part    Im not convinced at all. It wasnt intended to demonstrate audible differences, only to begin to establish whether or not there are...

  Quote:       Take a look at the green line and the yellow line and note the deviation. The delta is a shift of the signal at a very high frequency (Mhz range). Ive said it many time that this experiment was to quantify electrical differences and nothing else.    To...

Quote:   Im sorry but im unsure of what the purpose of this comment is?    Regarding this lab it was to test the electrical differences that manifested when the signal from the generator was sent through two different cables and compared graphically on an oscilloscope. Theres a lot...

Quote: The purpose of this was to view quantitative measurable differences using an oscilloscope. The next part of this was to qualify these differences to see if they are audible. Quote:   Originally my plan was to use a head with a binaural microphone in an isolating...

Denons just look warm...   I don't know how much of a correlation there is but its neat that you pointed it out    Nice observation.   Dave

@brconner Aren't digital commands voltage signals?    @ramicio   I am actually asking more because I was confused by a post about dacs of higher bitrate adding only headroom, while it seems that if they operate as summing opamps that would not be the case...     Dave  

Quote: I see, so are the resistors increasing in each step?   I guess my question is why are all of the inputs not unity?   Thanks for the input, Dave

@olor1n and sugarkang, Guys, I am not a mod but you are de-railing this thread. If you must continue to bicker like an old married couple please do some via PM.   On topic,  OP I think that you should wait till you get your STX and take a listen then. If you find the sound still lacking in...

Quote: This,   Or combine 3 and 4 and get a dac/amp combo for 500 ish.   Dave

How does a dac work?   No really, I mean does it function essentially like a summing operational amplifier?   If yes, would it be the number of voltage inputs into the operational amplifier that affect its bit depth?   If yes to the above question then doesn't the additional 8...

Quote:   As I have heard an airplane over my house I would disagree with you. However, if I lived in an area without any planes how could I say? While this seems odd, it is because I am arguing a fallacy.    You are straw manning a little as there may be differences in cables and...

Are you just trolling or have you tried it?   I would say if you have not tried it; telling someone they are not experiencing what they say is a bit of an unsubstantiated ridiculous statement or a personal attack...   I am not saying it would or would not make a difference as I have nor...

Quote: Answered in bold above.   Dave

@akart   You mention overwhelming evidence towards the contrary, could you provide some for me?  I have not been able to find any that lends significant conviction in either direction.    @sokolov91   I see you like DBT from some of your previous posts. Would you mind listing some of...

Quote:   As before, I answered in bold.   Dave  

Glad to see this being put together, I voted for the 19th as I will be on spring break, but I can probably make it any of the other times. I would just have to plan around academics schedules that I don't know about right now.   Thanks for taking charge again    Dave

If you want to go just a bit higher I would recommend the Burson 160.   Great with HD600s.   If not I would say my vote having not heard either but reading a lot about them would be: schiit asgard nuforce hdp (also above 500 but has a dac in it) used gilmore lite with dsp    ...

Quote: I replied in bold for ease of reading.   Dave

Quote:   For fun I would like to play devils advocate from an interview I had with George Cardas to answer your questions in a manner that I find appropriate as I would like to see what comes next as these are rational questions.   So allow me to answer for Mr. Cardas: His degree...

Quote: What science?   I can show you with an oscilloscope that cables have electrical differences.   To my knowledge no one has taken the time to analyze binaural recording of different wires in a system in soundforge or the like...   The problem with this argument is both...

Quote: If you find an audiophile girl, just tell her you have a big dac.   -Dac

  Could add the Burson Audio HA160 to your list.   I have the version with the built in DAC and it sounds excellent with my hd600s.   Dac

I read through this thread and I would like to start by saying that I have not formally studied in audio circuits.   That said, I feel that maybe the difference in external amplifiers can be explained in terms of the differences in the operational amplifiers that are actually doing the...
