Replace Bypass Cap?

[Monjul]

I installed the caps tonight.

Are you kidding me? Even with all cold electronics, I immediately noticed a lack of mid-bass bloat that has been getting on my nerves for a few years now. In fact, I thought it was the subwoofers causing the overhang but it wasn't. Now the mid-bass is tight and just as amazing, I can hear how much more open the sound is with increased articulation of instruments and especially vocals. It's downright scary and they aren't even broken in yet. This is the best recent upgrade I've made so far besting renewing tubes, replacing the coupling caps to Mundorf Silver/Golds which are terrific caps and replacing power cables. I don't think I'll miss the extra 200uf as it sounds like the system plays louder without strain.

Thanks! Now it's time to replace the filter caps in my 20 year old Kinergetics sub amp........

That's good news!

I'd agree that upgrading B+ electrolytics to something good (no need to be exotic) gives more mileage than tube replacement.

Could you confirm it was the KEMET-BHC ALS30 series part that you installed?

They are ALS30A102KE450's with date code 1002. They came in the original Kemet packaging listing the UK as the country of origin and sold to Mouser Electronics. They looked impecable and were packed well by Mouser.
