    Multitone test revisited: Level vs SINAD graphs?

    Howdy! This question isn't a request or directed to anyone; it's just food for thought. Most of the DACs tested in the past couple of years here all show the output of the APx555's 32-tone test signal in the review, which is fantastic because such a test immediately reveals flaws in the digital...

    ELAC Uni-Fi 2.0 (UB52) measurements (Amir was right)

    Hello, Some of you might remember the controversial UB52 review where @amirm found a nasty resonance, and ended the review there, for which he received some flak.. Some argued it is just the bad unit he received, and that we should not base ourselves on it, asking for Amir to test another one...

    Accurate speaker in-room response. Which UMIK1 orientation is better, horizontal 0º or vertical 90º? (Question)

    Although I've been using Umik1 for years, at first I always seem to have it right, but then the results end up driving me crazy with the same doubt: What combination of microphone positioning and calibration file gives us the real response our ears perceive at the listening point above the...

    What is Alan Shaw on about? (is "coloration" unmeasurable?)

    ..in this thread https://www.harbeth.co.uk/usergroup/threads/incoming-call-from-confused-audiophile.80461/ It starts with this: So I suggest in-room measurements: But he demurs: I’ve asked what is “coloration” that isn’t visible as frequency response or distortion (and how he is so sure...

    Hello again! After a move and stepping into a finished basement space, there was a lot of work to be done, and continues to be! Thankfully there has been some good progress made after a fair amount of messing about. I can't stress enough how much research, making extensive use of REW's Room...

    Loxjie D30 vs Fiio E10K - what to expect?

    So I was wondering what I should expect as far as the headphones output differences. Are they big? Where would it be audible? Is the E10K actually more powerful? Would it distort quicker? If anyone could explain that and maybe refer me to some stats so I learn - that would be great. Trying to...

    Standarized Measurement Protocols for E1DA Cosmos ADC owners

    I've just recently acquired mentioned ADC. It's great and precise tool for its price. I come to idea it will be nice to have unified measurement protocol for owners of Cosmos, so everyone can contribute with measurements of devices which Armir due to different reasons can't measure (distance...

    Quant Asylum QA403 with ESS DAC and ADC

    https://forum.quantasylum.com/uploads/short-url/e9EUxkUod8AstX3q4DM5uLsmMNL.pdf That didn't take long for them to replace the QA402. THD measurements in loopback and from external source look okish but those converters are capable of much more as demonstrated by several DACs tested here and of...

    Scandyna Blue room Minipod Speaker (in-room) measurements... I'm confused...

    Are they meant to sound this way? Like the measurements below, they are pretty dull on the high end. Do the measurements look like they're broken in any way? If they're not (both speakers measure similarly), what could the consideration be for such a sonic design? I've no idea what generation...

    Combining measurement methods to get a more accurate EQ - MMM + Gated Nearfield + Klippel Measurements
