great kit. I just popped these in and they sound amazing. Huge improvement. Its like I have a whole new amp. Incredible upgrade. Warmer, fuller, deeper, a 100% improvement!
Rolling tube give cleaner response.

I also bought the tube set for my new hybrid amp from Monoprice. First let me say the standard tubes were very good. I rolled the new tube keeping the old tubes in the tubestore boxes. At first I could not sense any real difference, but after a week of burning in the new tubes (I always wait until the tubes have 20 hours of use) I could definitely sense a cleaner response. I highly recommend the tube set.
Even better than the original tubes.

The original tubes work well, but the new tube package gives more detail. The soundstage is very wide, and I noticed something I wasn't expecting, and that's the artificial electronic additives so many recordings have (Adel, Sia, etc.). The separation is absolute, and individual instruments amazes me. Yes, I recommend rolling the tubes to the upgrade.
