In a similar boat, I've been going the rather expensive route of buying too much new stuff and unsuccessfully finding a sound/fit that I like. I have a bunch of stuff up for trade/sale here: http://www.head-fi.org/forum/thread/503850/ft-a-bunch-of-headphones-canada
 
If anyone's interested, drop me a line.

Well it's official my HF2 #455 (not B-Stock) is now posted for sale/trade on the forum.  See my signature.  Please PM me for the price if you're interested.  Reason why price isn't posted:  Some people don't read the entire post and forget I'm in Canada and want a price I cannot do to satisfy their TTVJ comparison price.

Guys, I need some help with something. I bought that attenuator from Khozmo.com and the information for it is as follows:
Code:
 Number of steps: [b]48[/b] Attenuation range: [b]-60 dB ... 0 dB[/b] Attenuation per step: steps 1 to 11 - 2dB, 12 to 48 - 1dB
Assuming you start at step 1 at -60 dB and follow these directions, step 48 should be 0 dB.
However, no matter which way I write it out, step 48 is -03 dB. What am I doing wrong? I'm trying to figure this out so I can design my attenuator case.
 
Here's my calculations:
Step,Level
1,-60
2,-58
3,-56
4,-54
5,-52
6,-50
7,-48
8,-46
9,-44
10,-42
11,-40
12,-39
13,-38
14,-37
15,-36
16,-35
17,-34
18,-33
19,-32
20,-31
21,-30
22,-29
23,-28
24,-27
25,-26
26,-25
27,-24
28,-23
29,-22
30,-21
31,-20
32,-19
33,-18
34,-17
35,-16
36,-15
37,-14
38,-13
39,-12
40,-11
41,-10
42,-09
43,-08
44,-07
45,-06
46,-05
47,-04
48,-03
 
What gives?
I emailed Arek at Khozmo, so we'll see what he says.

I assume that it's a typo and that steps 1-12 give -2db (thus -24db total), and steps 13-48 give -1db (thus -36db total)
 
Add that up: (-24db) + (-36db) = (-60db)

Well I am definitely interested in a meet in the pegg, arrived here a month ago and would love to meet some more audio nutts.
I am happy to bring my very modest setup that is travelling with me.
Audiotechnica ATH-A900
FIIO E5 headamp
M-audio Transit USB DAC
 
So keep those updates on meet details coming people :)

Glad to have you in the fold. I would like to compare the A900 to my balanced A700 (well, assuming I don't sell it by then)
