I’m at the 75 hour mark on the break in. The V2s definitely take longer to break on and that was confirmed by Jon Ver Halen. The V2s are opening up more and the need for more gain has dropped some. I never run out of gain on the V2s while using the FW SIT-1 which I was concerned about prior to the upgrade.
I think eliminating the Roon DSP 1.4dB of bass at 100 Hz and down (shelf) which I needed on the V1s is huge advantage for the V2s. V1 and V2 are both good but having more body and meat on the bone on the V2s eliminates the need for adding one or two subwoofers (in my case 2) because I can’t locate a single subwoofer centrally. So in a sense for my system, the $1500 V2 upgrade cost is well worth it considering 2 REL subwoofers, interconnects, and power cables would cost $7600. I also think the V1s with their added presence are a little of too much of a good thing. I mainly listen to jazz and I can say that I never have ear fatigue with the V2s. The V2s seem to match better to my all silver based cables which is a big plus also.
I tried my best to maintain the speaker position and toe in when I swapped in the V2s. On some recordings with the V1s, there was a less center fill and sometimes instruments were localized to the individual speaker. I never experienced with the V2s. The vocals are also more pinpoint on the V2s. One might say the V2s soundstage better. The magic of the V1s is clearly carried over to the V2s but he V2s extract every last bit of musical energy and impact on the recording. This is just my opinion. I also think reviewing a full range speaker such as the Nenuphar with a subwoofer doesn’t give the whole story on the performance of the speaker.
