    Heathkit A-8A Vintage Tube Amplifier Measurements

    Hello everyone, I am a vintage audio enthusiast who enjoys designing, modifying, and repairing tube amplifiers. I'm also an objectivist and a long-time reader of ASR, but I've always wished there was more tube-related objectivist content on this forum. As we all know, tube amplifiers are far...

    Crinacle bought the B&K 5128/4620

    He is going to update his database using the new B&K equipment. Edit: It surprises me a little bit this thread doesn't get any traction. I thought more people would find this interesting to discuss :)

    Apple TV 3'rd Generation - AirPlay measurements over TOSLINK

    Hello all, I was about to get rid of my old Apple TV 3'rd generation, A1469 model, due to the fact that it has no HBO Max, just Prime Video and Netflix and not sure for how long, given that streaming platforms will probably get updated in few years again, while this Apple TV model is already...

    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

    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...
