In the beginning, i had trans.-amps. ( 90s). With the little money i had that time, i bought a Kelvin-labs 25 W. Pure Class A (trans.) with magnasphere speakers (Magnat) In that time, the amp.always had to be under tension.He always made a slight hum,but the sound was greath. After, i bought Copland CT 405 (tube) ,audio analogique maestro,from then on Audio Monitor PL 300 speakers.THe sound was good, but not so “to the point”. THe speakers were very good,but i missed something in detail, and dynamic. After i bought Perreaux (trans), Primaluna, jadis D-03, Unison research 845.: the sound is “warm” very clear,dynamic,but not stll “to the point”. Very Nice to listening,not exhausting . The most of the cd’s i have, sounded good to exellent. Now , back to trans. :the esoteric f-05: the problem is ( if it is a problem).the sound is more detailled,natural,to the point,acoustic, holographic. Now with the ilumnia magister speakers. It sounds greath !! But good recordings are good,bad- sounds bad. Is this what i want? Yes, but it is no longer worthy of cd’s to listen to , because of shortcomings in the recording. It’s a choice:lovers of tubes, love the warmth of the sound. Trans-fans, love the depth and the pure accuracy of th music. This are my feelings. And now,i think this installation will be with me for a long time ( with the Luxman sacd D-06). But yes,what does the future brings... to all off you: enjoy your music!
