Well, I also have the V4's too, but you did not tell us is what type of speakers you have and what is the model number. but I choose to listen to my V4's on my Khorns and because of the sensitivity rating @ 105db you can really hear how the amps shines, I have not tube rolled yet, but that is coming down the road, but for you I can't tell you what your ears like to hear. Good luck
