+1 to @jollytinker 's advice.

@jollytinker Ha. You just gave me flashbacks to having my soldering iron pulled out of my hand by the magnets on my accuton drivers.  Fortunately just to the magnet and not towards the driver.  Super fun times!

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. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~


WEll now jusr wait 1 minute there


Are you going to tell us,,,

folks who ~~just purchased~~ past year lets say,,, the V1,,,with consideration of your ***accurate and unbiase test listenings*** That these V1 owners are now left with a speaker that is **a bit, if not to say a significant nuances*** less than what the V2 delivers????

If your listening tests are indeed accurate and spot on,, then seems to me to be ~~~FAIR in ALL THIS~~~, that Cube would offer free ship both ways, and free new cones at a nice easy going price cost to their loyal and haappy,,well once were happy,, now left in a lurch... Cube owes its owners some recompense for what they thought was the best Cube had to offer,, the V1. Now we hear the V2 is really *The Real Deal**. Something just aint right here. Something is smelling fishy if you ask me. Cube ought to take the hit,,and secondly,, why is Cube CONTINUINGG to list the V1 w pics.

Almost no info on the new V2 on the web site???? WE all need answers, Cube has alottttt of explaining to do on this ,,,to put it nicely,,,Conundrum,,otherwise know by another more common street slang term. You guys can do what you want,,, go at your own risk.,

,and expense.


Well if the V2 out performs the V1,, well then we will see some half off offers from  Cube on the V1's.

Or are they going to only sell the V2.

Delete V1 from their inventory,,and we are stillllllllllllll waiting to 

1) see new pics of the V2

2) read what is the **all new*** V2 cone material made of....what IF the pics of the V2 look almost if not identical to the **old version** V1???

Then what are we to assume???

Lotssss of Q's for Cube to answe,, as folks paid big bucks for these speakers.

Some ~~Fiasco~~ like this old V1, vs NEW V2,,might in the long run do more harm to the company than good.

Faith and confidence starts to take a  hit. 

And furthermore,,,what IF,,we get another review, which has some ((issues** with the above review,,, then what..??.

Who are we to believe.

Review with the 2 thumbs up,, or the audiophile who gives 1 thumb up, one down, and  goes on to say,,,**all in all, I prefer the old model version V1 better***

Then what???

This thing could start to get real ugly, real fast. 


abd1,  Just for fun, see if there is a polarity switch on your Streamer, DAC or Preamp.  Change the phase setting and listen.  You might not have the phase set properly.
