It’s been quiet for the moment in Absolutor stable but it doesn’t mean that nothing was going on there. Pretty much opposite. Last time we reported that their stereo amplifier to match excellent pre had been finished . It was based on designer’s favorite EL 84 pentode , of course checked in desirable SET ,eventually in PSE to get a bit more power on the output. It is still in accord to main concept. The circuit is SRPP type with the cathode follower based on the big power triode with separate advanced power supply ,with huge filtering reservoir and high anode voltage. After El 84 ,the chance had been passed to tetrode 807. Many beta testers liked it a lot for its analytical character and high precision performance, but not the designer. In his own words:
” .. I liked this valve a lot on almost every music material we tried. Rock ,Blues, Jazz, Vocals , you name it. It was always beautifully textured ,with perfect dynamics and vivid tonal balance ,but I had a feeling we are loosing something.On some classical material ,especially on Sopranos or on string and winds I was not happy with the sound. On this very demanding material it was possible to hear that as 807 is almost perfect with all the details ,articulation and speed ,but it lacks on the tonal accuracy. It sounded a bit to dry to me and for this reason lack sense of authenticity. Of course I could leave it like that as a finished project as many people suggested as it really sounded wonderful and already bettered many competitors we targeted with both the sound quality and retail value. But I wanted Absolutor Amps to be truly the best I can build, the proper statement….” We wouldn’t either as it is always all about the music , so about musicality as well. He stepped out then and moved toward Pentode 4654K. This one met finally high expectations. But time is passing quick as we all know when you are busy, hence almost 2 years passed since I have been listening to an Absolutor EL 84 stereo amplifier on time consuming tests and the final circuit shaping. In the case of appearance they are tribute to simplicity and elegance. It always was with Absolutor. Just to keep it as pure as possible to prevent its sonic ,hard worked out achievement.
Amplifiers can be connected via SE or Balanced signal path. Signal symmetrization is realized on transformers. Both ways the amps sound ABSOLUTELY charming with the matching ABSOLUTOR preamp, and any other you own or wish to connect.
