Related topic of someone with an SMSL DA9 (using the same MA12070 chip) running into interference issues with his powerline ethernet adapter https://audiosciencereview.com/forum/index.php?threads/odd-problem-with-the-smsl-da-9-amplifier.24061/

That's a serious electromagnetic interference issue. If I was a potential buyer, I would be very happy with this warning.

I think most people understand you can't take the risk of damaging loaned out equipment, so maybe a more carefull approach could already provide valuable insights. Most audiophiles understand an amp needs to have headroom to reproduce music with high fidelity, so people who are after sound...

I was asking for a friend ;) Meaning, I'm one of those pro's and all the amps we use run at max rated power for at least 24 hours non stop, driving low impedance loads, clipping leds flashing constantly, even when stacking 8 of them on top of each other. So for me it has always been a big...

But how will they know they've found an amp that can fullfill their needs if the power spec are unclear, that's the point of discussion I believe? It's not that Hifi amps than can deliver more than 50W continously don't exist. Looks like your best bet today is the size of the heatsinks and...

An amp from a renowed brand I bought new a few years back, spec'd 2×120 Wrms / 8Ω and equiped with 2 chunky 340 VA transformers. During summer, the thing shut down twice due to overheating while playing background music in my living room. The small (enclosed) heatsinks couldn't keep-up. The...

The ADC convertor used in this test has a SINAD of 118dB while the devices under test have a SINAD of 120dB versus 91dB. So when you replay the test files with a DAC that performs reasonably well (SINAD better than 91dB, which is very common) there is no masking by distortion of 'your combo'...

I had a look at the first example, the B&W805's versus the Devore 0/96's. The in-room response of these speakers is measured in different rooms; Art Dudley's versus John Atkinson's room! And the speakers have a totally different directivity and form factor (important for SBIR's and room modes)...

In the context of the question in the OP, they did for sure. The PMC was a third the size of the ATC and it blew the ATC out of the water in the low end. The result was that they both had to go. The ATC because it became clear their low end wasn't representative, and the PMC's because the low...

PMC is probably the most famous manufacturer of TL speakers, and they also use it successfully in small near field monitors. As mentioned before, they dampen the whole transmission line. https://pmc-speakers.com/technology/atl/ We used to have a pair in the studio, next to ATC's. PMC's for...

It's a new beta feature where you can make suggestions for others. You can thank me later ;)

I also have a large collection of albums on a media player, spanning more then 40 years of being into music. I love building a collection of music that I like, it's probably a hobby by itself. Never had a subscription to a streaming service. I do listen to internet radio when doing jobs in and...

Trying to break the ASR master thread concept ? https://audiosciencereview.com/forum/index.php?threads/master-thread-%E2%80%9Cobjectivism-versus-subjectivism%E2%80%9D-debate-and-is-there-a-middle-ground.29397/

And that's how 2k empty boxes are being sold. And in the end everyone's happy, so continue as you are.

And when you use monobloc's placed near the speakers to keep the speaker cables short, you need 2 or 3 racks in total, and racks next to speakers don't look nice.

Yes, and you should know that the Otari DTR-90, which cost and arm and a leg, had a S/N ratio of only 90dB.

For the first digital recorders we had in the studio (Otari, Tascam, Sony) 0dB analog input level was somewhere between -18dB to -12dB (digital) FS. And in the early days of digital we respected these levels! Now we're mastering to 0dB FS, using software to make that -0,1dB so no one thinks...

In small rooms you often have to deal with room modes and strong comb filtering effects due to direct reflections (SBIR) at the same time. That's where broadband absorption can come in handy.

Like I said, it's an attempt to visualize how energy is removed. Just another view on the same data. Not intended to give an accurate RT number according to the definition of RT.

A presentation for audiophiles, where Earl probably referred to the common 5 inch thick absorber panels sold on various websites. So lets look at the effect of 16inch/40cm thick porous absorption stacked 27inch/70cm high against 3 of the 4 walls in another studio: You can see how absorbtion...
