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….

Reach out to the builder to see if they would be compatible with your built-in amp.

Awesome! They should be able to hear the change immediately but will get much better after crossing that 150 hour mark and continue to improve past 300 hours.

I was considering a Loki Mini+ EQ but the positive change in clarity, smoothness and musicality these purifiers brought to my system and I have no desire for an EQ now.

I have been burning in my purifiers on my crossover less full range speakers and the difference is very noticeable.

These will ultimately go into my main system that utilizes a crossover.

Get with @ audioman58 for compatibility concerns with crossover less full range speakers.

Yes, you will start to hear improvements at the 200 hour mark and by 350+, you will be right in their sweet spot...😁

Ozzy,

I'm all tubes as well but I ran mines on my secondary system 24/7 for a month.😁
