    Adam Sub7 - a few measurements

    For a while now I've been thinking about adding a sub to my desktop system based around the Neumann KH120A. My primary motivation was not to get more LF extension (in the nearfield KH120 go relatively deep for the size), but to solve the bass dips in the 70-110Hz range caused by loudspeaker...

    Why does headphones measurement graphs always gets squiggly-er in the treble?

    I'm sorry if this is not the right place to ask this question as I'm quite new to this forum. But i wanted to delve a little bit deeper in the more scientific/physical side of the audio world. As the title said, why does headphones measurements always gets janky in the upper treble? I also...

    Suggestion: more audio interface measurements

    I've been following this website for a long time, and it is my humble and personal opinion that we kind of reached a saturation in terms of DAC and HP amp measurements. I think that for quite some time now, ever since say the Topping D50s, we reached a point where anyone that can spend about...

    B&O Beolab 9 measurements

    Hi all, Long overdue but finally done! I managed to measure my speakers with Rew. I measured using a umik1 microphone, in room, with the umik at my listening position. I don't use subwoofers or any eq. The first picture is the response with 1/24 smoothing applied; the second the raw result...

    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...

    New Room, New Measurements & What helped

    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...
