Geek Pulse: Geek desktop DAC/AMP by Light Harmonics

It depends on each individual amp, honestly. In most cases you'll find that the LPS cannot be used to power products other than those from LH Labs. There are exceptions, of course, but even the ones that take 12V 1.2A power may use a different connector for the power cable. For example my Violectric V181 has a different power requirement and power cable entirely; it cannot receive power from my LPS4.
 
The amps that will receive power from the LPS4 are in the minority.
 
My prediction: you're going to like what you here. But of course,

well, i loved the geek out 1000 i had, very nice

Great news on your Xfi. Hoping mine arrives soon too.

I am from Georgia as well. Both parents from small Alabama towns.
Now live in Shanghai and Berkeley.

well you're a long way from home !
 
i lived most of my life in macon, which music wise, was pretty cool i must say

Macon could have been even better musically if Duane and Berry had not ridden motorcycles.

In short, every +/-3dB is a doubling or halving the intensity. When you halve or double the intensity you're still maintaining the best possible ratio. All measurements are relative to -0dB, so the -3, -6, -9 etc are what you should be using.
 
If you're actually interested in learning specifics there are a lot of good resources online. This is a great place to start. If you want more detailed calculations and breakdowns I'd recommend checking out this page as well. The website layout is pretty crap but the information is good.
 
And an important note, I've heard people claim that bumping up 3dB doubles the loudness. This is not true. I had an audio instructor in college make such a claim. A few of my classmates and I immediately changed instructors because he clearly wasn't providing us with accurate information.

You propbably know this but doubling the perceived volume (psychoacoustics) is a 10db increase. So 3db for power or acoustic energy and 10db for perceived volume.

You're exactly right. It's right around +10dB that the average person perceives a doubling of volume.

I think you just saved my wallet from further destruction my friend. Don't think ill get the HPA so not going to get the LPS4.

Well, it seems that there are a pair of Xfi units sitting on my doorstep. I'll start playing with them tonight and let you guys know when I have some opinions.

ENVY!!

mine is here, inside, with me ! 
 
just have both the lps4 and the x/f/i unboxed, commencing to hook it up, get the drivers, and fire this mutha up
