    S.M.S.L PO100, PO100 PRO & PO100 AK - Measurements (Digital Interfaces & DAC)

    S.M.S.L PO100, PO100 PRO & PO100 AK Measurements Hey folks, It is time for my very last review of the year. A very special one, as there are three products to be measured today ! S.M.S.L released earlier this year the PO100, a tiny and fairly cheap USB to S/PDIF interface. Later in 2022...

    Are headphones frequency response measurements irrelevant?

    I've been obsessed with headphones measurements for years, specifically with frequency response measurements. But, I am yet to find measurements that match with what I actually hear. More specifically, none of the measurements match with what I hear when I run the SineGen. They are accurate up...

    Can I find Golden Ears (goldenears.net) measurements anywhere?

    As the title says. Are there Golden Ears measurements archived somewhere, the way Tyll's Innerfidelity ones are? Golden Ears measurements were THE best, and the most accurate I've ever seen. Unfortunately, the site is long gone, and using the Wayback machine is not smooth at all, plus a lot of...

    Why buy DAC with higher measurements?

    ASR reviews for DACs often capture "beyond hearing threshold'. We each are susceptible to psychoacoustics. For amps, we select from measurements, power and use features. For DACs in the 'Blue' zone of highly rated, why would we select one that has the higher cost, assuming features not...

    Discrepancy speaker Specs vs Measurements

    Hi wonderful audiophile people, so nice to have such valuable info and feedback on this forum. Been researching speakers that go deep in low frequencies and found discrepancies across both tests and specs. Notably about mean on-axis levels as well as frequency response range. 1. How can a...

    Measuring 2-channel Buckeye Purifi Amplifier Performance

    With Amir busy with house repairs, @Buckeye Amps and I discussed whether I might share some of my efforts to measure his Purifi amplifier as a stop gap until Amir can do so. A couple of disclaimers here as I am NOT an experienced electrical engineer and my QuantAsylum test rig is NOT as capable...

    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...
