Triode Pete Posted August 6, 2011 Author Share Posted August 6, 2011 Thanks guys for all your comments! I (& many others who heard my system) really like the sound coming from my mighty K-horns... Like I originally stated, I have a bit of audio nervosa & just thought there may be an audible improvement in changing out the GE motor run caps with a higher quality "audio" cap... I haven't heard back from VH Audio yet on some "accomodation" pricing for a 2 uF + 13 uF cap combo. I figured if it was "reasonable" to experiment, I would; if not I'm still a very happy camper... Thanks again, Pete Quote Link to comment Share on other sites More sharing options...
erik2A3 Posted August 6, 2011 Share Posted August 6, 2011 I think we all share that same affliction. Good luck with your cap experiments! Quote Link to comment Share on other sites More sharing options...
claus ernst Posted August 14, 2011 Share Posted August 14, 2011 DJK, I can confirm your measured results from a hearing point of view. Just poly sounds a subtle bit distorted in the harmonics of human voices, a PIO alone slightly dull. Their combination is clearly a progress. Even superior and my best results so far: Adding a small bypass silver mica on top of that. Did you ever try or measure any of these? c Quote Link to comment Share on other sites More sharing options...
djk Posted August 15, 2011 Share Posted August 15, 2011 The photos were from Steve Bench, the bypass was polycarbonate (the ones I have heard sound glassy). I haven't tried a silver mica yet. Polystyrene sounds great though. Quote Link to comment Share on other sites More sharing options...
jannegard1 Posted August 17, 2011 Share Posted August 17, 2011 hello itest new caps in my crossovers just for fun this motorcaps have nice soud http://www.ducatienergia.com/eng/prodotto.php?id=97[] Quote Link to comment Share on other sites More sharing options...
jannegard1 Posted August 28, 2011 Share Posted August 28, 2011 Technical specifications (according to manufacturer): “The dielectric is polypropylene film, the electrodes consist of an extremely thin metal coating obtained by vacuum evaporation. Case and cover are made with self-extinguishing plastic material; the capacitive element is sealed with polyurethane resin. The main characteristics of these capacitors are: Low losses non-inductive winding; Self-healing property avoiding short circuits; Small size and limited weight; No leakage risk; Capacitance tolerance: ± 5%; Working frequency range: 50 ÷ 60 Hz; Individual test voltage: Between terminals: 2.15 Vn for 2 sec.; between terminals and case: 3KV for 2 sec; Dissipation factor tan δ: <20 10–4@ 20°C V=Vn, 50Hz; Protection Case and cover in self – extinguishing plastic material; Terminals: twin cable, unipolar leads; Protection degree: with terminals: IP00; with twin cable IP55; Threaded fixing bolt M8” Sound: This industrial type capacitor (like the ASC and Inco) is quite nice! They sound a bit dull at first because they take a while to burn-in. But after a few days of normal use they deliver a reasonably wide and open sound stage. Nice and neutral, maybe a slightly warm sound. One of those things that don’t impress at first but sort of grow on you after a while, you learn to appreciate their qualities – great! Not the ultimate in sound staging or micro-detail and if you want a lively and bright sounding filter then this is not your cap. But if you are looking for a smooth, warm and relaxed sound then give these a try. that is the test of ducati caps Quote Link to comment Share on other sites More sharing options...
