Went for my first scooter ride since the accident. I can operate the Left brake and the turn signals just fine, and it sure feels good to ride in the open wind again.6 points

I believe Kevin tested some 300B's at Stax voltages and they were really, really unhappy. Fang naturally claims they are some special snowflake tubes but who in their right mind would believe that? They are most likely the bone stock Psvane garbage rebranded. This is a 400V tube max and since it is a DHT, there are some major issues to contend with. The earliest datasheet I found is this one and it states it is a 450V max tube but the later ones all state 400V. That means the tubes probably weren't happy at 450V. I'd be interested to see the 700V one though I'm sure it is a typo. The modern tubes certainly aren't built to take that level of abuse. If there are no output transformers then this is probably similar to the WES setup, hell it might even use chokes as the output load (as that should in theory boost the voltage swing but brings in a fuck-ton of issues) but simply a quad of single ended amps which all drift like mad. Now you could drive the tubes with resistor loads off a 600V supply but yeah...it will be pretty fucking bad. No heatsinks large enough to take the current of the 300B's to be seen. Ohh and I would never get in a fistfight with anybody for the sheer fear of being able to kill them with a single blow. It's not easy being a giant...5 points

Boxing Day breakfast. Joanne is having a veggie Skillet plus a biscuit just for Brent I'm having a German pancake, with the obvious accompaniments, which with the addition of certain fruits becomes desert4 points

I've been listening with the utopias a couple hours every night since I got them. I love that I can throw all kinds of recordings at them and they are always very listenable. They are my favorite headphone. Biggie.2 points

Before I believe anything written by mtoc and his claims, an actual link or reference should be posted here to steer away bs from real BS. I'm willing to bet if somebody had internal shots and overall outside shots of the Shangri la you can get it built for 1/8th of the price in China.2 points

Now that my PC has been taken off life support by upgrading to 16 gigs of ram and a 1060, I can play so many more games without causing another chernobyl in my bedroom.1 point

It's been fun watching them become the "supervillains" of the league, but all the blowing a 3-1 lead jokes are getting a bit old and now there's more fuel added to the fire from yesterday's game, blowing a 14 pt lead with another Kyrie game winner yesterday. Since the Lakers have been injured for the past month and completely destroyed any playoff chances, I just want to fast forward to the Warriors Cavs finals rematch.1 point

The following post was supposed to be much bigger, and posted yesterday. Inexplicably, imgur refused to accept any more uploads halfway through it. Today, imgur is STILL not working. I think it's the "I'm not a robot CAPTCHA failing." I spent half a fricken hour monkey with my adblock, and two other browsers. Got exactly nowhere. Here's as far as I got.

Boy, what a game on Sunday between the Warriors and the Cavs. That was fun to watch, even if my Warriors failed to seal the deal at the end.1 point

They are indeed designed as transmitter tubes but that is of little use for audio, Class B and all that. As you push the tube further past its max op point it starts to compress more and more and yup...more and more distortion. Let's say the tubes could run at 500V, no way to implement a CCS for them in that chassis and you burn up most of the voltage in the plate loads. Another point, yup this has nothing in common with the GES. Much closer circuit would be the Eddie Current Electra and we all know what a massive clusterfuck that was. Didn't work and drifts like mad. Also, weren't we going to permaban mtoc after he showed up with an another account during his last ban? I mean I can't take this level of retard any longer...1 point

from the 280 watts total power consumption and 24 watts going into the 300b filaments and another 12 watts going into the 6sn7 filaments the maximum going into the plate and plate resistor would be about 55 watts. so 20 watts into the tube and 20 watts into the plate resistor seems possible. that would be 80 watts going into that heatsink, it is going to get extremely hot. likely 10 watts into the tube and 10 watts into the plate resistor. Notice the trimpot thing on the back for dc control, so definitely no self bias. And big capacitors between the front end gain stage and the grids of the output tubes. Still going to drift like crazy, and most of the gain is likely the input transformer. or there is some solid state inside, unlikely. Or interstage transformers. Definitely worse than Mikhail's attempts. And looking at the tube data sheet, extrapolating for -100 grid bias the distortion is going to be over 5% with no extra gain for feedback. Definitely euphonic1 point

- I need to lose weight; - I need to cut down on my carbohydrates; - I need to cut down on my fats and cholesterol; - I need to cut down on my salt; - I'm lactose intolerant. So...yeah, pizza, once in a blue moon for me. And since we're friends on Facebook, you know that I had pizza twice within the last couple months, so...yeah, must forego for now. Just like beer. I miss beer, too.1 point

Funny how he tries to discredit (?) Stax for "sounding like you're in heaven" when they made the DAC Talent that used... guess what? That's right, PCM63s. Has he even heard or does he know anything about pre-bankruptcy Stax? Edit: I would love to see Fang try to get in a fist fight with Birgir.1 point

Well, Chicago Symphony Hall has had its critics about its sound quality since it was renovated in 1997 - see the Wikipedia article, so who knows what he regards as "ideal" live sound. And of course, the sound of a concert hall in recording, which, except for the occasional live recording, is done with nobody in the audience, sounds different from the sound at a live concert packed with people. Live sound is actually notoriously variable. The sound in the front rows can be drastically different from the sound in the upper balcony - I remember sitting in Boston Symphony hall in the upper balcony decades ago at a concert which sounded like a muffling blanket had been placed over the whole orchestra. So, no output transformers. Input transformers maybe to boost the gain? Or current source loads on the 6SN7s to boost their gain to the max? And incidentally, I found a Bell 300B spec sheet that shows current/voltage curves to 700 volts, so it can put out about much voltage as a 6SN7GTA if properly driven - more current, though.1 point

That is just pure win. Can the powerful amps damage the headphones? Yup but we account for that. Cavalli, Woo Audio and others don't give a shit about this so yeah...people should take care with those. This is pretty much the same BS as when I was laughing at the Jade crackling new out of the box. Fang claimed that the film was supposed to do that as it was coated with nanoparticles (read dust) which was somehow supposed to make it better. The Shangri-La has the same BS so again, nobody with any clue has been involved with the design. The King Sound sets also squeal like there is no tomorrow but they don't charge 50K$ for them either... Seriously, I might setup a Patreon account or something like that for people to donate so I can buy this shit and rip it apart for the world to see.1 point

Saw the Dr. today. Got the stitches out, and everything is healing very well. He does want a final visit in two weeks, but expecting that to be it.1 point
