Received my Nenuphar Mini’s Friday night. Got them uncrated and hooked up but it was late once I did so I played a couple songs and waited until Saturday morning. Listened to some music Saturday morning at low volumes and left them playing all day at lower volumes to start breaking in. Last night my wife and I turned the up and listened for an couple hours. I’m reserving judgment as they only have about 15 hours on them but so far there’s no weakness. I’ve tried single driver speakers before and I never felt they got enough extension on the vocals and could sound a bit restricted or muffled. Not these. My previous speakers had Accuton ceramic drivers and before that I used Salks with the RAAL ribbon. These are more detailed but still natural and smooth. I thought the Accutons would be more detailed but nope. The sound also has more scale and is more realistic. I’m still playing with location as my room isn’t great but they do seem to like being closer to the back wall. Bass improves and when I had them pulled out a bit the imaging beamed a little. So far also seems better with no toe in. I’ll continue to break them in and follow up. Wish I could post photos here. I got them in walnut and the finish is fantastic.
@abd1 Congrats! Looking forward to reading more as they break in and you settle on positioning.
@abd1 Great to hear you have your Walnut Mini's in system!!!

Keep us updated on the break in and final results.

Regarding photos, you can post / create:

- in the Virtual Systems area
OR

It would be great to see them.
I uploaded photos in the virtual system.

One issue I’m having is that when I turn the volume down I get a pop of distortion. I’m using a sachs preamp. I haven’t had this issue with any other speaker. It doesn’t happen every time but probably heard it 4-5 times. Mostly in the right channel but once in the left. Any thoughts?
