I would have asked you what you like better, but see in your post to drlowmu that you use Black Gate in the power supply. Since they're unobtainium, as Eli Duttman likes to say, I guess I'll still be looking for Plan B.
Thanks again for your reply. I thought about you yesterday, while warming up my Last PAS.
The Blackgate WKZ caps still reign supreme as far as I am concerned. I am hoping that Audio Note will soon release its replacement for the WKZ caps and that it will sound as good as if not better than the originals. The Audio Note Kaisei caps are ok but not a real alternative to the WKZ in my opinion.
In the meantime I have used Jensen radial 100uf+100uf caps in a couple projects with decent results. It is a distant second to the WKZ caps but if I can't use a WKZ the Jensens are my first choice. There are many folks who like ASC oil caps for power supplies. They just haven't worked out for me at all but for those who do like the ASC sound, I recommend GE 97F oil caps instead since they are less colored than the ASC.
The only Blackgates I ever purchased are FK 1000 µF 50V, for the power supply of a McCormack SS phono stage I was modifying. They were too large to fit, so I had to go with something else which would.
I take that back, since I also bought a couple of the 4.7 µF bi-polars everyone was raving about. They never got used either. After seeing what these things now sell for, maybe I should consider it!
I've tried clip-leading the ASCs into a tube amp's existing power supply circuit, and liked what they did, but always wondered how much of that had to do with the extra 60 µF per cap storage capacity.
At the risk of totally hijacking Jeff's speaker crossover thread, maybe we should move this over to DIY tube or Tweakers.
Thanks for the head's up on the Jensens.
It is not my position to discuss this, but I know of a VERY good example, of just the opposite of the results ( and build technique ) in single ended amps, that Mr. Vorhis, who is a friend of mine, is posting.
This may be my thread, but I can not take the liberty to discuss proprietary subjects up here, any more than I have.
Let me just say this. The technology and design of capacitors have not stood still. There are capacitor designs / implementations made today, that are considerably better than WKZ's, etc what we had 20 to 60 years ago !!
Also, only a few people in Audio know (a) what they are and (b) know how to employ the newer products.
Most DIY audiophiles I survey, on different audio Forums, are up to 60 years behind the times, in their thinking, and in their doing. This thread's responses, IMHO, is but one good example.
The answer to these questions is wisely, "Try it for yourself, and see". Fortunately, a couple of Wima DC links in the power supply will be much more affordable to try than a couple of V-Caps would be in coupling duty.
I'll give them a try in my next project, thanks!
Some of those doddering 60 year out of date thinkers also have years of experience and have seen the "new flavor of the week" come and go.
If you want more scientific testing info on a product then do more posting over at the DIY type forums. If you want to know more of how a particular thing rings out in actual use and how it ends up sounding then post here.
It's not that these guys are 60s out, but more that these guys have tried things that have come down the audio path road FOR the last 60 years.
And I apologize for not being supportive originally and I do look forward to hearing YOUR opinion on these caps.
Listening experience? Me ?? 72 years ago, I was listening to an ALTEC 604, my Dad's, in our home, as an new-born infant. I was there at home, as a six or seven year old when Dad brought in a second 604B ( new model) driver. So, I have LOTS of experience.
These new 4 pin WIMA DC LINKs will work out fine, not by themselves alone, but WHEN PROPERLY BYPASSED, ( as most, if not all film caps require ), for full musical expression. Implemented properly, they out-perform musically the old Blackgate WKZs, and at a fraction of the cost.
Sorry, I am not free to discuss bypassing properly.
Could be cuz most Audio Weenies are aged hobbyists,
arguably even into their Dotage :-) .. simply aren't interested in the latest claimed wrinkle.
I know I'm not.
Few Millennials (as a wide spectrum grouping) could care less about Audio 'stuff'.. in general.
Best sell yer wares..quickly :-)
I have had good luck with the FK series, and to a lesser extent the VK series, but not so much with other BlackGates.
That's good to know, since I've got several places I could use them.
I appreciate your feedback.
Here's a link to a description of the Audio Note Kaisei caps. At the bottom of the page there is a hint of a true BlackGate replacement but it won't be available any time soon.
