For quite some time I was using minimum phase room EQ filters tha I generated mannually with rePhase, but recently I decided to apply full scale time domain correction and go for linear phase response. As a result I got pretty nice looking phase, GD and step response graphs (measured at LP, 4m...

Ok, I will not say Revel performa3 F208 is a speaker with "perfect" anechoic measuements but most of us would probably agree that it measures really well. Here it is shown how well: I would say that if it wasn't for a little fluctuation in DI's around XO point at 2.2kHz it can really be...

So, would you be interested to know if our host, as a trained listener, can spot a difference between one of the best measured DACs (whichever is available to him) and a DAC on the low end of the green tier DACs in a proeprly conducted blind test? Or maybe even between one of the best measured...

So, I did a simple speaker distortion test with REW with sine sweep at 87dB level at my LP (4m from the speakers) and this is how it looks: Same graph in db scale. Green line is THD of my amp and blue line of my DAC: And here is the "sound of silence" in my room. So, next time when...

I'm considering buying a SW to enhance LF resposne of my Castle Harlech S2 speakers. Unfortunately, in terms of avialable space and WAF compatibility I can afford to put only one of them (I'm thinking of Kef Kube12b), so my question is how to time-align a single subwoofer with pair of speakers...

If you prefer to use REW not only as a measurement tool but also as a tool for automatic/manual creation of EQ filters here is what you should do to use those filters with BruteFIR convolution engine for Volumio: 1. Create your filter in REW 2. Export the filter you created using "Export...

I ran recently on the russian HiFi site Stereo.ru where I found tests of these 2 speakers. As each of them is a kind of king of it's domain (monopole and dipole) it makes sense to imagine "battle of the titans" to see how they would fare versus each other. So, which speaker won this monopole vs...

When trying to do room EQ measurements with REW you will find a lot of information on the Net. You have option to do RTA measurement with pink noise using moving microphone method. Another option is to make several sweeps at and around your LP and use "Average the response" feature under All SPL...

I kindly ask members to share their knowledge and experiences with manual room EQ. I'm in no way expert with this, here's how I do it.. I design my filters with rePhase based on measurements done with REW with calibrated mic. In the 20Hz-600Hz region I make RTA measurements at the area around...

Please post in this thread everything related to Volumio and BruteFIR.

What is your take, when we see a note on CD stating "digitally remastered" do we generally get a better a sound or not? :)

I believe it is safe to say that THD and IMD are no longer an issue with well designed DACs and amps. Thank God these days you no longer need to sell your kidney to buy such products as was the situation before. But how it is with speakers? How does THD and IMD of modern speakers, say Revel...

This poll is about your opinion on room EQ: do we need it or not, does it work or not?

Current Volumio users may find this news exciting as recently BruteFIR convolution engine has been ported to Volumio platform. At the very beginning I must stress a fact that although BruteFIR is available at all Volumio platforms I do NOT recccomend using it with Raspberry PI (including newest...

Does anybody hear know if Linn Kinsky is still supported meaning that bugs can be reported in hope they will be corrected some day? https://www.linn.co.uk/software

Can you hear it? :P http://abx.digitalfeed.net/

AES3 and SPDIF share the same low level serial protocol, but while SPDIF was designed for consumer market AES3 was meant to be used in professional envrionment. SPDIF covers max distance of 10m and is thus much cheaper than AES3, which covers max distance of 100m to 1000m, depending on the...

Seeing how well D10 performed on @amirm measurements, especially considering its very modest pricing, probably the same idea crossed minds of many of us: if only this little hero has volume control so it can be hooked directly to the amplifier! It would be even better if the volume could be...

It would be very nice if someone of you takes a little time and explain this loudness thing to the rest of us that don't really know what it refers to. :)

Today I received my D10. On this lousy pic you can see it attached to the Raspberry Pi 3 B+. As you can see it is still "work in progress" as I'm still waiting for the case to arrive. :) But ok, as everything is fully functional I decided to make a short write up to describe my impressions so...
