Hippie Hedgehog posted:Nah, being absurdly over-dimensioned for the application, I suspect it would actually not run very hot. PSUs generally don't get really hot until you approach their specified limit, and 2kW should way be more than even that monster of a PC could draw. Maybe if it was a switching power supply. Linear power supplies run REALLY hot, and a 2kW monster would have to be that large - just to fit the massive toroidal transformer and the heatsinks to cool it. Check out the chart on this page: http://www.raftabtronics.com/TECHNOLOGY/ElectromagneticBasics/ToroidalTransformerBasics/tabid/112/Default.aspx You'd need a transformer 8 inches wide, 3.4 inches high, and weighing 26 lbs to drive a 2kw PSU - and you could probably boil water with it. Also, is that a C13 connector? drat thing is gonna start a fire. Edit: Just to put the nail in the coffin of stupidity - Linear power supplies have HORRIBLE efficiency. quote:For a large voltage difference (i.e., low power supply output voltage) and large current, the overall efficiency can drop down to nearly 10%.

I found this picture of one of those garden hose power cables, which is connected via a standard extension cable, then into a regular-ish power outlet, which has a normal thin cable going to a socket... what exactly do they think this magic cable can do after the current has passed through all the standard wires? Not to mention the tiny wire in their household fuse and standard power cabling in their home. Go big or go home: It's a 100 amp power cable for a Yacht.

Philthy posted:I haven't had good luck with Monoprice. I've had quite a few bad HDMI cables from them in the past. I don't even know that was even possible. See, that's odd. I buy a ton of stuff from Monoprice, and the only thing I've gotten from them that I wasn't happy about the quality was a 50 cent 3.5mm to 1/2" adapter. But it works and it cost 50 cents, so I'm not particularly worried about it. Then again, I don't buy HDMI cables from them any more since my best friend installs cable and has boxes full of them. My point still stands that if you're spending more than 5 bucks on a 1M RCA cable, you're doing it wrong.

Jerry Cotton posted:Audiophiles > Oenophiles > Beer nerds > IPA nerds > Pepper nerds. This is how I see it, so it's the absolute truth. People who pay 40000€ for some cables are down right crazy but people who have ever used the term scoville outside of academic conversation are deplorable scum. (I don't know where camera geeks fit in because I've happily not been subjected to camera geekery.) See, I really like craft beers, and I don't think I'm nearly as bad as an audiophile. I mean, hell, the most expensive beer you can buy is like 600 bucks a bottle, which is probably 1/100th the cost of the most expensive cable you can buy. Also, most of the really expensive beers are expensive because they're limited runs or just really drat cool. Like a beer from SPACE or one that comes in a termidaxied squirrel.

KozmoNaut posted:Tube amps are awesome for making music, not so awesome for playing it back. Right, but I consider that analogous to a filter being applied during mastering. It's part of the original song, and it's meant to be listened that way. Using a tube amp to listen is like putting one of these in your system (except worse, because it only has one setting and you can't even turn it off). http://www.amazon.com/Lexicon-MX200...fects+processor Again, though, I like my music played back as analytically as possible (within a modest budget). I'd rather use software to apply effects or EQ if I think a song sounds better with it. If you think Bach sounds better with tube distortion, go for it. I think a lot of tube fans are old timers that grew up with tube distortion and it sounds wrong to them without it. Also hipsters, I'm sure.

Khablam posted:The physical properties that cause a bike to balance are incredibly complex, very hard to accurately model, and not fully understood. If I wrote 5000 words about how my bike design was better able to get you to school than the others because of my research on mass-center and gyroscopic dynamics, centrifugal balancing and ensuring I consider gravity, I might not be particularly lying. The ironic part of this post is that electric cables are much better understood that bicycle dynamics. Hell, coaxial cable was patented in 1880, and it's still used today for uncompressed 1080p @ 60FPS. http://en.wikipedia.org/wiki/SMPTE_424M The skin effect isn't some magical property that only a select few cable manufacturers understand. It's a well understood phenomenon that is intrinsic to any conductor with a very simple solution - using braided 'Litz wire'. So, no, BJC doesn't have some magical solution to the skin effect or any other scary scientific term that Monoprice doesn't. The only difference is that one was made by a guy in the US in a union, and one was made by a guy in China working 80 hour weeks for almost no pay. Is one going to have superior build quality? Probably. Does any of that have anything to do with R&D or some secret technique? No. You know what the difference is between an HDMI cable that supports 1080p@60 and one that supports 4K@60? Nothing. Any Category-2 rated HDMI cable is capable of 4K resolution @ 60FPS. You're not going to see any problems at 1080p unless your cable is out of spec. TL;DR: There are only 2 things that matter with (passive) in-spec Category 2 HDMI cables - wire gauge and quality control. Everyone uses the exact same wire design. Now can we stop arguing about cables? KillHour fucked around with this message at 03:04 on Sep 11, 2013 |

The point of 24 a bit DAC is that you have 8 bits that you can dedicate to changing volume on the computer without affecting sound quality. Obviously, that still means that music encoded beyond 16 bits is still pointless.
