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 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.

Using MAGICO Q3s they have the best crossover, cabinet and drivers ill pass.

I have a psaudio p12 regenerator and a preamp with its own regen power supply. My speakers are single driver full range. Curious if these will make an audible difference. Wig says there is in his system. Is there a trial period?

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

Are purifiers beneficial on Magneplanar speakers, and has anyone tried this on MG20's? I have rebuilt/replaced the stock internal crossover components with Janzen silver and Audine copperfoil capacitors with Dueland 14 Ga air core copper foil inductors. There are Mundorf 0.01 MFD Silver foil bypass caps in parallel with the Janzen Caps. After a lengthy break in the speakers sound much improved. Will these purifiers help more?

Thanks!
