I took delivery of my VR4 Gen III's just 3 weeks ago & have been trying to burn them in. Sad to say I only have about 20 hours of hard break in time on them but the manual recommends 100 hours of LOUD VOLUME run in. My dealer said his display pair took about that long, so that's what I'm shooting for. I've been stuck at home for the past few months-so without going into detail I'll just say I'm working on it.
I auditioned these & was very pleased with the increased bass & high freq. response along with a big soundstage.
This past week I managed to get 3 hours of loud electronic music on them Thursday & then listened to some Diana Krall. Very nice as they are listenable after a hard run. I know things will improve & I'll be able to sit without fatigue for hours on end like I used to. I am trying to get the final position worked out during the next few weeks & will adjust a little here & there before I put the spikes on. With my wall 2 wall carpet that will tighten the bass up another notch but it already is sounding good.
I also have to mention that the first few hours that I cranked them up my Ayre V-3, although it has the latest upgrades & is 7 1/2 years old, had that electronic smell like it was burning in. I mentioned this to my dealer & he said the Ayre probably had never been driven that hard before & indeed was burning in. Reinforces that word, burning in, for the non-believers. The smell went away after two sessions. Due to space constraints I can't face them & put the cables out of phase for break in.
The music that I've played & have been able to sit down & listen to had bigger bass-meaning lower freq. response & presence. Big bass was an absolute requirement for me & I now have it. Even at this early stage it is not boomy & will tighten up even more. The high freq. response is very pleasing although I have the fill tweeter turned down almost all the way. I just can't stand brightness at all & will have to work on it. I also was just tonight able to move the speakers away from the wall to stay & they are only 17" away from the back wall. When listening before I had to pull them out then push them back because a vent was too close to one of the speakers. I rectified the situation although I only have about 6 more inches more to move out.
I had to wait 4 months for these speakers because of the demand right before the price increase. Also, this is the first retail purchase I've made other than a $150.00 IC in 11 years. Everything else has been used, demo or auction. That in itself says something. I can't give you the full review but going on what I heard at the dealers showroom, which was more like a living room than any other showroom I've ever been in & he used the same IC's & one set of the true bi-wire cables I have. That gave me a pretty accurate representation of the things to come.
Also, my living room is 22' x 11.5' x 8' & I moved my listening chair back & now sit 14' from the speakers. Great imaging. I wasn't so sure I should have bought them before taking delivery because buying retail is something I haven't done in a very long time & I also found it hard to come up with 4k but I'm glad I did it. Definitely takes my system to the next level.
