Here is a set of 96/24 format FLAC files recorded from various DAC and amplifier outputs that you can compare against each other and a reference file (A.flac).   The list of files - warning: more than 500 MB total download size:   sample.flac - the original sample (created from several...

Here is a small set of files that tests the quality of the audio recorded from two DACs. It includes level matched and synchronized samples for ABX testing (I do not think there will be many positive results, though, maybe some for the onboard), but perhaps more interesting are the "difference"...

I plan to create some ABX tests, and am looking for good samples that could be used. If anyone is interested, post your suggestions, or even better links to actual files (of course, without copyright problems, if possible). It would probably be best to use multiple short (<30s) samples from...

The following article shows the results of a farily extensive test of the Xonar D1 PCI sound card. In my opinion, this card is very good value for its low (less than $100) cost, and can - if used in a machine where interference is not an issue - even compete with the ODAC. It is also available...

Here is a set of FLAC files for ABX testing, that compares the line output of onboard audio (Realtek ALC887) and Xonar D1 to a version of the original audio that has been upsampled with high quality software sample rate conversion. There are two tracks that can be used for testing, both were...

Here and here are some audio files recorded from the output of various low end (including some very old) PC sound cards, while driving 250 Ohm headphones near the maximum volume; in all cases, the actual voltage on the headphones would have been in the range 0.93 to 0.99 Vrms with a 1 kHz 0 dBFS...

Hi! Is there anyone who has used both of these headphones ? If yes, how does their sound compare ? I did do some search and found information about both, but it would be better to hear from someone who has actual listening experience. Also, there seems to be a "II" version of the HD 215; how (if...

Hi! Sorry for creating a new thread for this, but in the "Buying headphones" thread I got no response. I am looking for some advice on buying one of these headphones, or a similarly priced one if someone recommends it and I can find one for purchase:   - Sennheiser HD428   - AKG K99   -...
