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...
