Futterman versus whatever

It is a bit tiring to read about comparisons between the original Futterman and other OTL amplifiers. The Atmasphere for example is built with modern components that were not available to Julius Futterman. The electrolytics in the Futtermans are at best 30 years old. How can you expect such an old amplifier to show what the circuitry is capable of?

Today a friend and I ran a comparison between my original old Futterman H3AA and my friends H3AA where all the critical component had been replaced (all electrolytics, coupling capacitors and so on had been replaced as well as meny of the resistors) some of the capacitors had been increased. The difference was really remarkable. Although mine sounded very pleasing it could not compete in terms of low end power performance and clarity. The sonic signature was the same. However the resolution an attack in his amplifiers went all the way down into the low register. The dynamics was certainly also superior. The top end was similar although his amplifiers had slightly better control.

So please take these facts into consideration when commenting on the performance fo the original Futterman amplifiers.
