Hi @abd1 ,

The problem in your room is the glass windows and door on the left, which cause very strong first reflections and ruin the soundstage and image.

You should try draping the windows on the left. It doesn’t have to be heavy curtains. Perhaps even a light tulle will suffice.

Regards,

Alex.

 

I'm thinking about getting some GIK floorstanding panels to place at the reflection points along the wall with windows. Also last night I toed in the speakers heavily so they cross before the MLP. Made a big difference. Sound is very centered now and separated from the speakers, still very deep. Soundstage is smaller, but my speakers are about 8' apart so still pretty good. I'm guessing toeing in totally changed first reflection point.

V2 drivers for my Nenuphars Monitors (coupled with a Sub 12) arrived 10 days ago.  Run them 24/7 for a week, then started listening seriously.  V2 is a more refined version of the original F10neo drivers: it does not lose anything (the mid-range magic is fully there), sound is thicker across the entire spectrum (more presence / more meat around all bones) which increases the sense of naturalness & flow. I did not have to tweak my system in any way (MU1-Tambaqui-Icon4se-Amp23r or SIT3, LessLoss cabling), the V2s are here to stay! 

Vinpic  Thanks for your impressions of the V2 drivers. You didn’t mention soundstage or imaging which I assume meant no change but just wanted to check. 

No change, still amazing ☺️
V2 it’s a welcome evolution (no revolution).  As I write this I am listening to Grant Green’s Idle Moments masterpiece.  With the V1 the Gibson and the saxophone edged on the shiny/dominant side creating a sense of imbalance vis a vis the other instruments.  The V2 adds meat to the bones of the bass / drums / cymbals whilst making the Gibson/sax sound more truthful (at least to my ears).   The overall balance and listening pleasure goes up one to two notches depending on the piece of music.  The most impressive difference I’ve listened to date has been on Willem De Vriend’s Beethoven 7th (DSD file played off the MU1 ssd).  The V1 was a bit too bright and did not reproduce accurately the dark/grave strings base (I did know it was there by listening thru my Susvara’s). Spent months trying to tweak my system to no avail. V2 got everything in the right place without losing an inch of the Nenuphars’ mid-range magic.
