Hi Folks,
Following the excellent advice received here in modding my Rotel RCD 955AX CD player, I replaced the two Blackgate 100uf electrolytic capacitors in the analogue output stage after the opamps stage for a couple of metalized polypropylene 4.7uf axial's.
There was certainly no need for electrolytic's in this position, I guess Rotel fitted them as cheaper than using Blackgate polarized capacitors in this position.
Anyway I digress, shopping around I found the usual high quality well known polypropylene brands rather expensive just to try this mod and see what the result would be.
Whilst searching the web, I came across JB Capacitors, a Chinese manufacturer, http://www.jbcapacitors.com/Plastic...ized-Polypropylene-Film-Capacitors-Axial.html I ordered a couple of their Premium capacitors as in the link and they arrive swiftly within a couple of weeks from China.
After installing them I did notice an increase in clarity and treble response over the Blackgates that were previously installed. Overall very pleased with these capacitors and will not be going back to reinstalling the Blackgates.
Has anybody else had any experience of using JB Capacitors and what are your thoughts ? There's not a hugh amount of information about them on the web, but what there is, is all very positive and I can add my experience to that.
cheers.
Lee.
