In case you guys didn't notice, I'm posting this as new thread so it can contain more information
What is Burson? They produced world's best discrete opamp and I witnessed cheaper Audio-GD's discrete opamp for its goodness. If you guys remember Stello HP100 quite well, they claimed they use full-discrete class A but that's only for preamp not headphone. They use IC discrete opamp which is not full discrete like Burson or Audio-GD. Too bad, I didn't find this amp much promising for $600 price range and now it's increased to $1k.....
Now the most promosing discrete company making headphone amplifier. This product is just introduced in this month so not many people would know this item or even its company for headphone amplifier field. I'll try to put hilights from his website so you guys don't need to read all stuff and organize its information below:
Hilights
-employs an advance discrete power supply and power filtration network
-the Burson opamp technology has been channelled into a head phone amplifier
-completely free of ICs (integrated Circuitries)
-built with a differential input stage
-no decoupling capacitor on its signal path
-Powered by 2 pairs of top quality Toshiba transistors delivering up to 700mW of driving power into 300ohm!
-The entire head amp is configured in Class-A operation to remove any cross over distortion that may otherwise occur..
You can find more information here HA-100 Head Amp They're selling it for $1,150AUD (About $760USD)
They offered introductionary price in eBay in Burson HA-100 Headphone amp suit Sennheiser AKG SONY - eBay Other Amplifiers, Amplifiers, Audio, Electronics. (end time 26-Jan-09 02:32:28 AEDST)

I hope this time it'll be something better than my last ones for discrete headphone amplifier.
