measurements

..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...

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...

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...

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...

Thanks to @hardisj for reviewing Polk Audio XT speakers. XT35 center: US$300/ea Preference Score (according to Erin) is 3.9 Preference Score (according to Pierre) is 3.8 XT30 center: US$200/ea Preference Score (according to Erin) is 3.6 Preference Score (according to Pierre) is 3.4 XT20...

Hypex UcD180HG HxR module analysis and review After buying and testing AIYIMA A07 amplifier (based on TPA3255 class D chip) in January 2021 I was quite disappointed with the frequency response modulated by speaker complex impedance and its audible consequences. This is, unfortunately...

Another very interesting review by GoldenSound. I was expecting better measurements from dCS, even if it is their entry level product. https://goldensound.audio/2021/10/12/dcs-bartok-with-headphone-amp-measurements/

Hello all, This will be a summary of (many :)) measurements I did with the Neumann KH 120A that I recently purchased. The pair were manufactured in 2013 and sport the older, IMO slightly industrial looking finish: A few notes on measurement methodology: The loudspeaker has been measured at...

Audioholics has posted a video of their livestream discussion on "Improving Loudspeaker Specifications Standards for Consumers" I am curious what people think of the discussion. I have not listened to the whole discussion yet, but skimming though some sections I had some thoughts. 1) Curious...

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...

All, One of my customers send me this amplifier interested in how it will compare against the Starkrimson Stereo Ultra. Anyway I figured I would also post the measurements here for everybody's benefit. This amplifier is current selling for $595.00 on amazon All measurements are with 8ohm...

I posted this on the HTM-12v2 thread, but thought it was an interesting enough concept that people might want to do it with other speakers and thus I am posting the info here as well. I had a fun little project today and wanted to add a layer of active EQ to my HTM-12v2 and wanted to compare...

Anyone else interested in seeing ASR add raw driver reviews with measurements? ASR already has the required equipment perhaps with the exception of a IEC baffle but that's an easy afternoon build. I think such objective reviews would be of great benefit to the DIY sector of the audio community.

I recently purchased a pair of Elipson Planet Ls and again some Planet Ms. I got some for great prices and wanted to add surrounds that would be permitted by the wife. The Ls do look very nice in Mercury Ice on the dedicated floor stands! Given they are both concentric driver speakers I...

Little Dot D300 preamplifier measurements I purchased the Little Dot D300 pre through an Australian reseller. It is a hybrid tube/opamp preamp. My use case was to add as a switch/level control for my analog sources (turntable and tuner) that go into the ADC of my RME ADI-2 pro. If it added...
