Hi Everyone,
I'm sure this question has been asked many times before... However I'm just not having much luck finding the answers I want by searching -- probably because there's just too much good advice on all matters hanging around!
I'm looking for a good DIY amp project for Grado SR-80 phones with a crossfeed circuit. Read on for more background.
I've recently acquired an iPod, which re-invigorated my enthusiasm for music. Somehow in the last 10 years, I stopped listening to music all the time. I used to listen to it pretty much non-stop.
I quickly noticed that the iPod headphones were uncomfortable and fatiguing to listen to. So I began my search for a replacement set. Like everything I do nowadays, I research on the net before I buy. I'm not happy to have low quality products unless I know what I'm getting into because i've had to comprimize due to cost.
After reading mixed reviews, I decided to get a set of Grado SR-80 headphones for home listening. Fortunately, they were one of the few good sounding phones I can find in town readily.
At first, listening to the SR-80s was more fatiguing than the iPod phones, however, after what is now about 40 hours of break in, they're sounding much nicer. I'm not yet "experienced" enough in audiphile terminology to describe the subtle changes that have happened during break in, but they are much more pleasing to listen to now than when first plugged in.
I started to notice that some recordings are disturbing when listened to on headphones due to the strong left/right seperation... So I started reading up on crossfeed filters, which I had previously heard mentioned when researching headphones.
This got me fiddling with WinAmp and Foobar, with no satisfactory (or even any results for that matter). I also fiddled with the headphone setting of the Audigy 2 ZS Creative drivers. I didn't like the flat sound. I've been listening on my PC using 2.1 speaker mode, or using my iPod. In the end, I uninstalled the Creative drivers, intalled the xk project drivers, got the crossfeed rigged up in the DSP and had a listen. Even if the setting wasn't optimal, I could feel a huge difference while listening to tracks that had too much left/right seperation. The recordings no longer sounded unnatural and jarring.
Unfortunately, I can't keep the kx driver installed, as it breaks the 3d sound in games, which I also play a few of. So I have the Creative driver back installed, and need a new way to get crossfeed filtering.
I could just build a crossfeed filter, but frankly, I suspect the Audigy 2 (and to a lesser extent, the iPod) do not have strong enough amps to drive the Grado phones optimally. The biggest hint about the Audigy 2 amp being weak is the fact that listening at the same volume to the same recordings on the PC is more fatiguing than the iPod. If the Audigy amp is weak, I can't imagine that the iPod is that much better.
So -- I'm competent with a soldering iron and schematics, so I'm looking to make myself a (not necessarily portable) headphone amp with a crossfeed filter in it. I'm not looking to go broke, however, building my first amp. I'd like something that has as little noise as possible (as neither the iPod and Audigy 2 has any audible hiss at any volume setting on the Grado phones)...
Cheers and thanks in advance.
