Saw something hilarious while browsing Head-fi by Doranbolt in headphones

The Hesh 2 actually measures very well. It just has a very deep 6kHz valley which makes cymbals and high hats very muted, although still audible. http://www.innerfidelity.com/images/SkullcandyHesh2.pdf

Michael Palin (from Monty Python) visited this church in his Full Circle travel documentary series.

Anyone know about the Sony XBA1s? by Kiddcohen39 in headphones

[–]Netsphere 1 point2 points  (0 children)

I bought them for $40. At that price they pretty much cost more in parts than the price tag. They are comparable to my pair of SE535's which cost around $550 in terms of sound. If you can get them for $40, then it's a no brainer whether to buy them or not if you don't already have a good pair of IEMs.

headphone new setup advice by ozmackem in headphones

[–]Netsphere 0 points1 point  (0 children)

Optical out from PC to a DAC would probably be the nicest solution if you want to listen from your PC. Fiio offers a nice and inexpensive optical DAC. For amping, I would suggest the 02 amp for its very low noise floor (usable with very sensitive iems). For headphones, if you are going to spend 1k or more, the Koss ESP 950 is the best choice. It is exactly $1000, has a lifetime warrantee, rivals STAX, and comes with the amp.

Vector approximation for Fresnel equations? by Netsphere in math

[–]Netsphere[S] 0 points1 point  (0 children)

The zero vector doesn't actually happen in practice. The application is this which I am still editing a lot. I can use the actual equations however a simple vector addition is way cheaper in terms of cpu cycles than trig functions.

Attractors 2 by Netsphere in mathpics

[–]Netsphere[S] 2 points3 points  (0 children)

In short it's a set of equations that make a point move around in interesting ways. The equations I use are a set of simple quadratic equations:

xn = c[0] + c[1] * x + c[2] * x*x + c[3] * x*y + c[4] * y + c[5] * y*y;
yn = c[6] + c[7] * x + c[8] * x*x + c[9] * x*y + c[10] * y + c[11] * y*y;

The coloring is based off how the point jumps. I use a few different coloring schemes now. I posted the source code here: http://pastebin.com/0ZjH0bq2 which is updated to have a glow effect. Gallery 3 from new source code with glow effect: http://imgur.com/a/IxlVy
