Duelund/Mundorf Ultra Loudspeaker Purifiers


I have been eying the Duelund/Mundorf Ultra Loudspeaker Purifiers that Audioman58 have been advertising and knew based upon the forums I have been following for years that he was quite knowledgeable on capacitor typologies.

So, I took the plunge and ordered these and they arrived in 3 days to my SW state! I knew from experience that they will need over 200+ hours just to hear a glimpse of what these Duelunds are capable of but they didn’t disappoint right out of a cold box. I immediately heard more clarity, a deeper soundstage with better separation and a much lower floor noise…

These purifiers have been burning in 24/7 in my secondary system for nearly 2 weeks now and are really starting to open up. I listened to these purifiers last night in my primary system with just over 200 hours and the change was quite remarkable; musicality, tighter image focus, much better decay and note sustainment, unbelievable airy and spacious 3D sound, more vibrant and engaging sound with clarity being the standout.

These purifiers work as Audioman58 described and I’m still shaking my head on the beauty I’m hearing in my system and would Highly recommend this amazing product….

I have been tempted, but my speakers have built in amplification for the bass and wonder if it would damage the built in amp?

I checked with Golden Ear yesterday and they do not recommend using on my Triton Refs, saying it could possibly damage the internal amp and DSP. With that being said, although I would love to try it, I don’t gamble so I very reluctantly will pass. Unless of course someone with my speakers is using them successfully.
