Hi guys,I replaced 12 stock electrolytic caps (teapo) in the signal path of my amp with 10 Standard and 2 Non-Polar Black Gates, and after 2 months of burn-in, the sound is better in some ways (lower noise, better detail and resolution) but tonally it has become a little colder and leaner, which is not of my liking.
I was wondering if by using Black Gates Non-Polar or FK instead of the Standard ones would I recover some warmth in the midbass, or if it would be about the same.
Does anybody have experience with the different Black Gates? are they tonally different? Or should I try something different... maybe Nichicon Muse?
Thanks for any input.

To my ears, the FK and N are far superior to the PK. The FK is sharper, the N needs longish run in. The C is cheaper and very good.
My experience is just the opposite - instead of thin and cold, they are warm, rich, and bloomy (not overly so) and get out of the way and let you hear the music.Not sure how many hours "2 months of burn-in" represents, but depending upon the actual number of caps replaced and their position in the circuit, it is my experience is that the BG's (all) take anywhere from 200-1000 hours to completely settle in and sound their best. During the burn-in process they can at any time sound thick, thin, fuzzy, phasey, lacking bass, etc. It is also my experience that the non-polar N's seem to take the longest, especially in the cathode bypass position.
I usually leave the amp/pre/DAC/transport run (with signal, not just "on") 24/7 for several weeks before making final judgement.
hope this helps
Thanks for the input. But is there any difference between the Standards and the FKs or Non-Polars? is the difference worth the cost?Thanks
My experience is the WKZ's are best for PS filtering applications, the "BG standards" are better than any "standard" electrolytic, the FK's, PK's etc. are better than the standard BG's, and the non-polar N, NX, and NH series caps seem to be the best, but these are only available in low voltage sizes. The "ultimate" is BG-N High-Q non-polar in Super E cap configuration. I use the NP N Hi-Q in SE on my digital boards and for cathode bypass applications.I think you just need to let them "bake" for a while longer... Let me know how they sound after another hundred or so hours.
I totally agree with you for the description of those Blackgate capacitors. I think they are still the best electrolytic caps available and the only problem is they take so long to settle down. My experience is that the sound still improves after 1000 hours.
