ADCOM GFA-2 si GFP-1A amplificator si pre amplificator Americane profesionale.Se vand numai impreuna .Amplificatorul este unul de exceptie,cintareste 13,5kg si asta se datoreaza in parte faptului ca are 2 transformatoare(nu unul ca la mai toate amplificatoarele de putere) cite unul pentru fiecare canal.Pre amplificatorul cintareste 5,5kg si are printre altele si posibilitatea unica de a conecta 2 pick up-uri cu reglaje speciale la spate pentru dozele folosite ,moving magnet si moving coil,vezi foto 3.Eu personal nu stiu sa mai existe un pre amplificator care sa si calibreze dozele de pick up.Am cautat in magazine de Hi-Fi Hi-End un sistem amp-pre amp care sa fie flexibil si sa faca fata si la muzica clasica,opera,opereta,jazz,rock,etc. Si se stie ca pe Hi-End Americanii sunt super tari.Fiind Americane functioneaza la 110v si necesita un transformator de 500w care nu este inclus in set.Nu discutii de pret sau pareri ci doar legate de vanzare.Ofer si cer seriozitate.Nu trimit in tara(sunt foarte grele si greu de impachetat)asa ca doar predare personala.Poza # 4 arata sistemul meu de unde provin cele 2 piese.
