[sdiy] Sprague 150D "Tantalex" caps as audio coupling caps?

[aankrom]

I seem to recall reading somewhere that someone (maybe on the 
DIYstompboxes or DIYaudio forum or maybe just a web page about different 
caps...) that they had used Sprague 150D "Tantalex" caps as audio 
coupling caps with good results. Anyone else have experience with these 
in this regard? I ask because I have a decent collection of various 
sizes. They look like they'd stand up to time quite well, being 
hermetically sealed much like PIO caps. I have no doubt that they'd work 
great as bypass caps or for power supply decoupling. I'm curious about 
their audio performance compare to run-of-the-mill tantalum caps (which 
I am usually loathe to use) or aluminum electrolytics. Can't remember if 
I've asked about these before...
