Mundorf coupling caps

Dgarretson
Are you saying with certainty that the BAT's use Jensen Oil in paper?
They sure look similiar. Do you have experience with the Mundorf M-Cap Supreme Silver/Oil (oil impregnated, silver metallized polypropylene dielectric) cap...? THink this is as good as stock bat cap?
Thanks

Indeed BAT oilers look identical to Jensen. My assertion as to their identity follows several posters and webzine reviewers who have stated that BAT PIOs are specials developed by Jensen.

Of the Mundorfs I have tried only Silver/Gold. They have handily surpassed REL RT and Hovland Musicap in my line & phono stages. But the most immediate & dramatic improvement was replacing BAT PIO with V-Cap TFTF. V-Cap TFTF was also a major improvement over REL teflon in my LS. In my system the phono passes signal through two Mundorf Silver/Gold and one V-Cap TFTF coupling caps. The CDP passes only through two V-Cap TFTF. These sources sound damned close, which I believe testifies to the quality of Mundorf.

Dgarretson, thanks for all your inputs,you have help me saving time on the path of trying different caps, i have installed jensen copper PIO on my cary superamp and so far not passing the break in time but it sounds pretty good comparing to the stock kimber caps, i have ordered some mundorf caps silver/gold for my cary rocket88 as coupling caps also for my audible illusion L1.i will let you guys know how they sound with cary rocket88 and AI L1,my next adventure will be V caps if my budget allows me.Have you changed out those electrolytic caps on your equipment power supply with better one? if so, is there any improvement? and which one is good and affordable eletrolytic caps available today. Many thanks and have a happy holiday

Tim, Jensen 4-pole caps are good, if expensive. Rubycon ZA and ZL work well in small filtering positions. Space-permitting it's effective and cheap to parallel Rubycons up to whatever capacitance is necessary. This can get large in battery supplies.

I put the Jensen/BAT PIOs into Cary 2A3SE monoblocks, where they improve upon the stock Audio1 coupling caps.
