Let me ask you this Roger; other than one of Ralph’s amps, which modern era top-tier tube amps have you actually sat down and listened to with not just your own planar speakers, but also modern coned speakers across a decent spectrum?
Other than designing amplifiers Roger has a pretty robust repair business and is an authorized repair shop for Allnic. Lots of vintage and modern equipment, solid state and tubed, crosses his path. I know because for the last 3 years I have been the repair intake person. As he has mentioned previously, Roger also measures anything he can get his hands on and has notebooks full of test notes for equipment that spans the ages. Also, Roger does not design planar speakers, he designs electrostatic speakers, there is a difference, perhaps you might read up on that.
Are you living in a cave?
Actually he has quite a nice house with a very nice system.
When we’re bored we go visit local folks to hear their modern systems (this past weekend we heard Avantgarde horns with their associated electronics) and Roger is pretty active with the SFAS, with the responsibility for running the upcoming phonostage shootout in January. My point is that Roger is very up to speed regarding current designs and design "philosophies," but testing and measurements are still critical to producing quality components and the principles behind these measurements go back in time. Ohms Law is still Ohms Law after all. Unless I missed something it hasn’t been updated or modernized.
Same is true for balanced amplifier design. Today we see all sorts of designers referring to their equipment as balanced. In many cases the design is just balanced at the input, not throughout (then there are the pseudo balanced designs). The only person I know that has been doing true balanced tube designs consistently (and in adherence to the balanced standard) has been Ralph Karsten and he’s been at it for over 40 years. However, the concept is not so modern, in fact it wasn’t developed for home audio use, but rather first utilized by the phone company to drive long cable lines (although I am unclear if the phone company developed the standard which I have heard referred to as the 600 ohm standard).
So Fred Sonic Smith (I assume that’s what your handle references) perhaps you should leave us. You bring zero value, you do not possess the knowledge or credibility to refute anything Roger says and although their opinions greatly differ, at least Ralph has the credentials and reputation to partake in those discussions. Let him do so if he wishes, he needs no help from you.
I re-entered because I could not resist. I saw that your irascible behavior has continued and not just towards me, so I felt better about re-entering.
Actually that was your cue to leave and stay away. You re-entered because you enjoy trolling here.
