Yesterday I built two more Pootie Pies, one with a display and one without. So I now have four total. Using one of the display units in the bedroom with the SMSL stack and the other with the DAC Magic Plus on my desk. That gives me two headless units to use for testing purposes. If anyone wants to try one out, I can send it your way. All the units use RopieeeXL, so you do not even need Roon to use them as you can turn on DLNA, Airplay or Spotify to stream.

I second the NCore and Purifi-based amps recommendation. My all-in-one uses modified Purifi amp modules and is pretty awesome. The Hypex UcD & nCore, and the Purifi modules, are all from the same core designer, Bruno Putzeys; and that was the first Class D I REALLY liked..... The new NAD M33 DAC/Streamer/Amp uses the Purifi modules, too. The others use (slightly modded I believe) nCore modules.

The Chinese gizmo finally arrived after I extracted it from UK customs. Interesting so far. Measuring in my office, which has the computer, UPS and monitor I get 350mV In the kitchen with none of the LED lights on, 100mV and with all the LED ceiling lights on, 145mV. So the switched mode supplies inject a decent amount of extra garbage into the mains. Plugged in to a Russ Andrews Signature Powerblock, 40mV. So the good news is that the power block - which among other things contains a bank of mains X rated capacitors between live and neutral - seems to be doing what it says on the tin. More playing around is going to happen....

As a couple of you know, while the pandemic continues I'm switching remote video events/meetings from my house. My desk has four MacBooks running endpoints, videos and slides, an ATEM switcher, a multi-view monitor and a do-everything-else fifth control MacBook. I'm out of space (so adding normal sized extra monitors is out) and need more from that control MacBook (usually running 4-5 apps during events that I need to instantly view, often without hands to jump between). Which lead me to this. By chance anyone have experience with it or suggestions for similar? I wonder how the recent MacBook's top/screen would handle the weight?

I'm not sure if there are less added taxes/duties but Amazon es does distribute OWC memory. You could go to the OWC web site, get the part number, then find it on Amazon es and try ordering it there (search Other World Computing). If you have any question about the exact part you need, the OWC sales folks will be happy to tell you. If you have enough space, dual boot. https://www.macworld.co.uk/how-to/mac-software/dual-boot-mac-3659676/

When your life is under threat, you'd better be careful what you grab

Another FB find.

Since I know of nowhere else to post this, I am going to put it here, after singing a song into it and auto tuning the fuck out of it. #MusicMaking.

I ended up getting the Mackie ProFX10 v3. It does everything I need, plus a bit more, and they had it in stock in the brick and mortar independent store where I got my first drumkit at 14 years old.

Well cheap compared to all the monster amps out there So correctly done, one would do the Uberamp2-Raal edition, which results in something really big,heavy and lot of heat. And a custom and large chassis, and a pile of $$$ This is a bit cheaper and easy enough for just about anyone to do. From the Ti Opa541 datasheet, showing paralled opamps good for at least 7 amps rms of output into anything including a dead short... Designed to be mounted directly to the heatsink, amp board right angle to the heatsink. All wires to the board directly soldered, 4 oz copper highly recommended. Power supplies are a minimum of 24V at 10 amps, like this, but more current not a bad thing. You need a pair of these! https://www.mouser.com/ProductDetail/MEAN-WELL/UHP-350-24?qs=YCa%2FAAYMW011AuZKubw9Sw%3D%3D So by the time you get done, about $400 in parts. Better than spending $4500 on an unknown made in croatia thing with inside pictures deliberately hidden. .02uf is a film cap, 10uf are mlcc caps, .1 ohm resistors are caddock https://www.mouser.com/ProductDetail/Caddock/MP930-010-1?qs=%2Fha2pyFaduhEz86YdyVUnzk8BCJOExJuzQrioCIidHi6TdsKxEEAVg%3D%3D raalopamp - CADCAM.ZIP

They're a pretty reputable company, Shelly. A couple solid steps above DIY, but they've been doing it for several years (if not longer). They've had some decent designs on the Hypex modules, and now Purifi. The NC ranges are all Hypex nCore, with different modules or levels of extras/quality. The Purifi uses the Purifi modules. They also have one amp that uses the Stereo ICEEdge module, used to be B&O but is new (and better then the older ICEPower modules). I actually have a tweaked out EVS dual-mono ICEEdge amp I'm selling too (a measly 600wpc 8ohms/1200 into 4). But of all, my personal preference would probably be the Purifi amp modules. I don't think Nord did as much to tweak the input stage as my all-in-one builder has; and if Ric Shultz @ EVS decides to build an amp using the Purifi module, he'll tweak it for best sound too.

Benchmark is a Class-G amp with an SMPSU, so it's more akin to a Class-AB. The Mytek is Class-D and uses Pascal modules which aren't bad, but I don't consider them to be of the same level as nCore and Puri-fi. And has DIRAC which will make the biggest audible difference. If @shellylh can swing that, then it should be pretty much perfect.

So I bought l biscuits, but I didn't eat them. Idk how that works, but if so, my bad.

While i had 727II with SR-009, SS Dynalo with HD800 was getting most of the playing time. After getting the the RME and its parametric EQ, the SR-009 almost got sold as i did not really see the point of owning it. If i did not find the SRX+ and decided to build one for myself, they would probably be gone already. Bought 95x locally and for cheap, decided to use it for backup and testing. HD800 took a step back to the SR-009. After that i got an itch and decided to build the Carbon. Now i generally use the 95x. Carbon removed a good part of that gap and they are a lesser pain in the ass somehow. I think i need the 007s..

These bookshelves aren't that power hungry. The question is how wild is the impedance/phase curve. For what the ATC amp has under the hood the price is a daylight robbery. I don't know what's your disposition against Class-D, but recently I heard an active system based on Hypex nCore amps and... it was pretty fricken great. Maybe see if one of NAD's newer M-series power amps are available for a good price. Nord Audio nCore and Puri-fi amps are also a superb value.

New to me!

For your viewing pleasure. Elear Clear Utopia Sennheiser HD650 All measurements were performed by Sonarworks. They do DSP-based headphone and speaker calibration. During the 5 years I was with the company I can say that even now they're hard to beat in terms of headphone measurements. Mostly due to the fact that all measurement curves are checked by audio engineer ears so that they make the headphones sound as close as possible to a known tonal reference. All of these curves are averaged from at least three different samples from the headphone in question. I can't tell much more about the actual method. Just make sure you only compare them to other Sonarworks curves.

Here's some measurements of my Linear Tube Audio - MicroZOTL mk2, with Linear Power Supply. I'm powering a pair of Lowther TP1 speakers. 100mW output is the loudest I listen at, usually much lower. 200mW would be @pabbi1 levels. Tube Complement 1: - Brown base Sylvania 5692 - Valvo (Philips) 6201 gold pin Tube Complement 2: - Red base RCA 5692 - Sylvania 12AT7 It looks like my tubes may be better matched than the rest of the circuit 1mW output at 8 ohms 10mW output at 8 ohms 100mW output at 8 ohms

Smoke em if you got em

Headphones ordered roughly by decreasing frequency of use: Audio Zenith PMx2 (really convenient!) Stax SR-007A (mid-2015 revision) (paired with a KGSSHV Carbon or KGST) Campfire Audio Andromeda JH13fp (of course) Oppo PM-3 (for closed use, often when playing (digital) piano) Sennheiser HD600 (mid-1999!) Still consider the HD800 an excellent headphone albeit one that benefits more from EQ than any of the above. Heard many current-TOTLs, consider most of them underwhelming or flawed compared to the above. Curious about ZMF products, never had a chance to try one unfortunately. Speakers, including inexpensive ones, surpass all of the above by a large margin, but I don't live alone so can't rock them too often.

I’ve moved to stronger psilocybins and now enchanting sirens follow me wherever I go.

This a dozen times.

I can confirm that this works very well. 😁

Nothing like a tropical storm and 28 hour power outage to re-arrange one's week. 😳 🔫

113 confirmed dead, looks to increase. 4000 injured, looks to increase. Estimated to be around 1/3 the explosive power of Hiroshima. Ammonium nitrate storage facility, three thousand tons of the stuff. I'm almost shaking having watched that on the BBC news. RIP everyone in Beirut It has destroyed whole swathes of the city.
