Tempted but it doesn't look like a huge difference from a fully upgraded 2. I have MANY stereos and I've said this before I think it's possible that my SEX amp sounds better than all of them. Love the sound of it. Most smooth, detailed amp I own. I use it at work with a Linux Computer running Clementine and a Fiio E07K USB DAC and the old famous cheap Insignia speakers all the rage about 10 years ago.
It doesn't sound like much but it'll make your jaw drop.
SEX amp always has been and always will be a winner.
