Quote:   The short answer- upsampling adds no new information to a digital signal, but I can come up with a couple of situations where an upsampled data stream could aid in the transition back to analog The longer answer - Upsampling in its simplest form does not add any information...

A small follow-up: I've build an AMB gamma2 DAC for my work desktop setup.   Since I am in a shared office, I tend to listen at pretty low levels ... somewhere around 10% on the Windows 7 mixer (this is on a Macbook Pro). My primary complaint with the Macbook's headphone jack was the...

Thanks for an interesting read!   Regarding the article ... there actually is one small issue with digital sampling at twice the frequency of interest (i.e. the Nyquist frequency).  While the Sharon-Nyquist Theorem correctly states that the frequency information is maintained, the phase...

First & foremost - Thank you milosz for a great contribution to this forum   Next - Since there seems to be some disagreement about the likelihood of an improved source impacting these comparisons, I wanted to throw my 2 cents in from a technical perspective ...   If one starts with the...

andre,   I'm new to this as well and am probably all of 1 day ahead of you in research  ... but I'll try to save you some of that day :)   I am currently debating between a DIY option and the FiiO E7. One of my main reservations about the E7 is that there seem to have been some build...

For those who have used the D5000 with the E7, what is the max volume that you use? See below for why I am asking.   My best guess on the gamma2 output is 0.049W per channel.  This is from the VRMS at the gamma2 spec site and the maximum continuous current from the AD8565 output buffer...

Any final thoughts on the gamma2 DIY DAC versus the FiiO E7?   I feel like I am trading  off between a higher quality source but likely lower power (I have not verified the power output) for the gamma2 and a lower quality source but with better power & portability with the E7.   I...

Darkninja67 - Thanks for the info since your setup is nearly identical to one that I'm considering! With the low price on the E7 over at dealextreme (~$82) this is probably my top commercial contender given your feedback.   powerlifter450 - I agree that the asgard looks like quite a good...

The DIY options competing with the commercial options listed above are based off of my reading so far are:   1) a GrubDAC (~$45) paired with a Pimeta (minimal $75 / better components $150) 2) a GrubDAC (~$45) paired with a Carrie (~$85) 3) One other suggestion that I have seen is to use...

Thanks for providing such a great community! I'm just starting to dive into head-fi (this is my first post), and I am overwhelmed with all of the knowledge and help provided in these forums ... now onto my question :)   I have a pair of previously loved D5000 on their way. Now the question...
