measurements

Hi there, first post here, I hope this is the right place to post this I've been reading a fair amount of headphone amp and dac/amp reviews on this site, and I've noticed that the output impedance measurements on products I've looked at are usually well above what they're advertised as (Fiio K5...

I have compiled a massive 'subwoofer comparison' spreadsheet. So far, I've found +1600 subwoofer models in total and +300 models with CEA-2010-A data. But there's a lot of interesting subwoofers that weren't tested. I'd like to see a discussion thread dedicated to which subwoofer models, we...

Double blind wine tasting (and the impact of the bottle)? Coke vs Pepsi and functional MRIs? Very interesting topics to read about that highlight the complexities of human perceptions and all the factors that influence it. I have read a lot of behavioral economics and psychology books...

I've created a *slightly large* subwoofer comparison spreadsheet. :D Info: -==Link to my Subwoofer Comparison spreadsheet ==- https://bit.ly/SubwooferComparison

Hi! I have recently finished setting up my HT/stereo system consisting of Kef IQ90, IQ60C, IQ30 and dual SVS PC-13 ultra with upgraded amps. I'm using a Denon AVR-X4400h to drive my setup (7.2). Attached is a REW measurement of my untreated room. The room is L shaped 3,3 x 5,8m (10,8 x 19ft)...

[This thread is now closed as the Tableau dashboards are no longer in service. Please refer to the Master Review Index to see the latest information regarding ASR data + dashboards.] Hi everyone. I wanted to let folks know about the new ASR Review Stats dashboards. With these dashboards you...

As the title states this is my first foray into taking actual room measurements. I'm a firm believer in room acoustics, speaker and listener positioning, distances from walls and speaker boundary interfaces. I'm using a UMIK-1 ver2 on a boom stand. USB into my HP Envy Tower --> USB RME ADI-2...

Introduction @Dennis Murphy is generously sending a pair of his Philharmonic BMR Monitor speakers on a road show to various listeners east of that big river over yonder. Somehow, they found their way across it to rural-ish Texas and landed in my home first, before heading back east to continue...

As we all know, headphones, similarly as speakers, have non-linear and frequency dependent impedance. This non-linear impedance creates a divider with headphone amplifier output impedance, so the distortion measured at headphone amplifier output (behind its intrinsic output impedance) would...

I'm just curious if anyone has measurements/a performance analysis of the following: https://www.aiyima.com/products/amplifier-aiyima-a07-tpa3255-2-0-channel-300wx2-hifi I'm quite tempted to purchase one as I've heard good things about the TPA325x series of amplifier chips, and I like...

Here are some interesting new measurements of the Kii Three. https://www.soundandrecording.de/equipment/kii-three-midfield-monitor-im-test/

I am totally new to doing loopback measurements in REW, this is my first try, so please correct me if there is a better way to do this. I have a Focusrite Scarlett 6i6 2nd generation audio interface and connected the Output 1 line out into the Input 3 line in using a 1/4" TS cable with about 2...

I’ve been thoroughly enjoying my Sony NWZX300 – a beautiful (yet flawed) little beast. Great interface, stunning build quality, snappy performance... but significantly underpowered. Also, there's no "Enqueue" or "Add to playback queue" function, which is a real shame! And beware that buying one...

I posted this on another thread but it is too interesting and deserves its own discussion. Dan is a legendary amp designer formerly from Krell and nowadays with his own company. Went from designing deeply based on measurements on the later Krell days to less reducing distortion and more...

Mola Mola Tambaqui DAC (€10,000 or $13,400). XLR output level 6.15 Vrms according to the manual. AudioPrecision APx555 measurements courtesy of the Audiophile Magazine review linked below. Full scale 1kHz Full scale 19+20kHz...

Up until recently I was using the Digilent Analog Discovery 2 to perform audio measurements on my DIY audio projects - with 14-bits of resolution, it's a surprisingly powerful and cost effective little device. And while still an exceptional and blisteringly fast scope - I honestly can't see...

Given that the MiniDSP SHD and the RME ADI-2 Pro fs both use the same AKM chips, have similar specs, and in Amir's DAC testing showed very similar performance, is it safe to assume that the ADC performance of the MiniDSP SHD is likely to have a SINAD within a few dB of the RME ADI-2 Pro fs? I...

Marantz SA7001 CD/SACD player Marantz SA7001 is a nicely built unit of the year 2006 that was capable to play CD and SACD discs. As now, it only plays CD discs for me, so it is only tested as a CD player. Photos of the front and rear view SA7001 has detachable 2-pin IEC mains cord Photos...
