It's reasonable to make statements like the one filburt made. I have a problem with his dismissing things he hasn't heard, but in that case, he was suggesting that things should be done for a reason, not just because they could be.

The statement is a truism that I thought relevant to the tone the thread was taking: a tendency to dismiss an idea without giving it a fair chance when it does not fit in with preconceived notions. I expect to see that sort of approach on the other site but not here.

Much of the verbiage on the Burson site, as well as the Audio-gd site, is audiophool bullshit. Burson dismisses opamps for being based on a single silicon strata, which in reality is as much of their advantage as is their disadvantage. Use of a single strata can accomplish much tighter thermal bonding, and achieve much more closely matched device characteristics than is easily accomplished in a discrete design. I'm certainly not adverse to discrete designs; it is what I use in my CD player for I/V rather than opamps. Touting a discrete device, essentially based on opamp topologies and yet not documented (specifications) thoroughly as any opamp would be, as being the ideal component for any opamp application is asinine.

See here is the problem. You can't have good pnp's and npn's on the same piece

of silicon no matter what you do. You optimize one, or the other, not both. One

has to be vertical, the other has to be lateral.

In theory with really well matched discrete parts, you can do much better.

If you spend the time and can actually get the parts, you can do much

better. These days, getting the parts is the hard part. The other thing is

that most opamps are limited to +/-15 volts. If you want something in a

class above that, it has to be discrete.

Here's the head-fi review of the HDAMs vs. opamps, which I was too lazy to link in my last post:

Audio-gd discrete op-amps reviewed: OPA-Earth, OPA-Moon, OPA-Sun v.2 - Head-Fi: Covering Headphones, Earphones and Portable Audio

His summaries of each generally agree with what I've heard. They need 350 hours of use before the sound settles, if anyone ever tries them.

Hey that's great. He definitely spent a lot of effort like Skylab does.

Hrm he seems to say the GS1000 is a "top class dynamic headphone" post long burn in. And his other headphone is the RS2. Yeah unfortunately any headphones I use sound way too dissimilar for me to have any context from this review
