All can say is wow! As you know I am a conductor of classical music and can honestly say that it is like hearing cd's for the first time - Jeffrey Milarsky, Conductor of the Columbia University Orchestra.
With a creamy, natural sound and tight bass response, along with pro-grade build quality to match, we're sure any serious music lover would enjoy this fabulous piece of audio bliss.
WooAudio has one of the prettiest and slickest build quality that you can find in the industry. Everything from the hairline finishing, the lines, the knobs, the transformer housing, all the way to the back panel, you find nothing but top quality workmanship.
Awesome! Amazing sound! I know I use these heavy words now and I promised myself I wouldn't as I do not get excited very easily and I did not want to cause a stir with this review and then make people have high expectations. But I do think the sound is indeed awesome.
I never really knew how good the HD-600's could sound until hearing them through the WA6. Anyone that says the HD-600's are dark or veiled hasn't tried the correct headphone.
The soundstage or spatial placement of sound is excellent, but in my opinion this is also dependant on the music, recording quality and headphones used. Overall clarity is excellent, it sounds natural and the sound is clean/undistorted without a morsel of off sound or graininess.
I just wanted to let you know that I received my WA6 yesterday in good order. Though I know it is not broken in yet and it will only get better; after a couple hours of warm-up time it sounds totally awesome. So good in fact that I listened to many favorite recordings long into the night. And the fit and finish is first rate at any price, for the money I am VERY impressed to say the least. - Email noted by RD.
