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.
