    Hello Dragan,

    The first ten years I used a pair of old RCAs in my system an was happy with them. Last year I was able to find a pair of KenRads. And they sound very HiFi…by comparison to the KenRads the Sylvanias suit my listenig preferences better because they seem to highlight voices, or lets better say, they bring out the charakters of voices a lot better. I listen to Leonard Cohen, Laurie Anderson, Nick Cave or J. Cash – to name some of the popular voices… even the newsman on the radio is more dominant. I like that.

    The Sylvanias have a different balance compared to KenRads. They do have have this strongly though precise articulated bass which brings my system to its limits. Voices can sound strained and stressed over the KenRads when the volume exceeds a certain level. That is not the case with the Sylvanias.

    To make it short: The Sylvanias bring back the magic into my system – at least an idea of it. Perhaps a dual monoplate Sylvania would do it even better. A Fivre 2A3 would do it maybe even better. Do you have these tubes in your stock? It must not neccassaryly be the Fivre Monoplates, a doubleplate would do.

    My system: Music Connection Musiqua No. 3, Preamp No. 12, Micro Bl 111 with Mission Mechanic-tonearm ad GradoReference MM, Philips CD 103 Stage 4 (redone by Roman Groß), another CD-Player Dynastation No. 3 (on sale) and a Kenwood L01T Tuner, 96 db Dynacox BiConic Speakers, the german Dynavox, now named Dynamikks.

    Kind Regards

    Hello Dragan,
    Could tell me more about the Sylvania CHS 2A3? Especially the type of the top filament construction (“hanging by “fishing rods”, spring or simply hold by holes in the top mica.)
    Also what is the measurements and your price with shipping to France.
    Kind regards,
