Hi,
Great topic. I love the design of B&O.
I also take decent vintage equiptment, and take it to the next level and beyond by removing bottlenecks and improving things so the performance is up to the standards of today. Vintage gear can sound really good, if you know what you are doing.
I also took a glance at your list of capacitors, and i gave to give a word of warning here.
The silmic's would certainly NOT be my capacitor of choice, and here is why:
They color the sound in a pretty extreme way. They add a lot of highbas, lower mids, and voices start to sound dark, heavy and nasal. Also they remove all harmonic distortion in mids and highs. A distortion guitar sounds really "sweet" when you use these. Piano attacs are dead and lifeless, same for highheads, drums etc. They are terrible, remove all mids and high dynamics. Your system also looses a lot of speed. I have done lots of experiments with them up to six months, even after a extended burnin time things where not looking up. A lot of people seem to like them, and i really cannot understand why. There are different series, series 1 is somewhat less bad compared to series 2.
They do image very well, soundstage is great. But it's the only thing they are any good at.
Only suited for pa systems, which have to play very loud.
If you are looking to add some warmth in a system, try nichicon finegold.
The combination i use for voicing gear is finegold, and ukz. Also good imaging, transparant mids.
I use gold tune in power supply's when there is room for it.
I hope this helps you in any way.
Best regards,
Nico.
