HiMy Accuphase T-101 tuner has a lot of tantalum caps in the signal path. I thought replacing them with Black gates caps. Will I get better results by using non polarized BG instead of using polarized BGs. The tantalums inside this tuner are polarized caps.
Thanks
Follow Ups:
I have upgraded electolytics a few times with blackgates but it has always been in the power supply path. The non polar blackgates can be used where a "normal" polar cap is on the DC line. This can provide excellent results, especially in a digital circuit. I would look at paper in oil caps for the audio signal path instead of electrolytics.When you say the caps are in the signal path, did you mean the RF signal path? This is interesting . . . .
Electrolytics are very common in the signal path of op-amp based stages. The values required make PIO's and film caps prohibitive for both cost and size, let alone the fact the PIO's and films are not even available in values commonly needed. Direct coupled is better in these beasts of course, but if you like the gear you have on a basic level, then this tweak is a good one unless you're into the idea of a complete redesign. At that point you may as well replace the whole damn component.

I must admit that I don't know anything about the Accuphase T-101. That's why we need to know more about where these caps are and what they do before we say "Yeah, go for it man!". It could be a bad idea to upgrade caps in the RF stage of a tuner just because we have blackgates available.
I think a common mistake made in this forum is to just start swapping out parts because we have better parts. I know I went too far with blackgates in my DAC and took some out. I hate to see anyone get bad advise and would like to learn more about this myself. Some people spend a lifetime voicing equipment and we cannot just assume that better parts will always make things better.Still learning and having fun,

The BG non-polarised caps are great sounding. As I understand it, the "goodness of sound" goes:
N --> NP --> NX (although possibly NP = NX?).A further trick - particularly for coupling caps - is to use 2 'N's (of half the required value) in what BG call a "Super E" configuration. Here, the long lead of one cap is paired with the short lead of the other (even though they're non-polarised, they still have a long lead and a short lead!).

THey say the non-polar are best for couplers. I've used polarized (to save money) and they were an improvement over generic electrolytics. It can be done, but if you can afford the NP's, I'd go for those.
