I am enjoying the 150.8. It has taken some time to grow on me but my speakers needed some break-in as did the preamp. Things are smoothing out quite nicely. At first I wasn't sure I was going to warm up to the amp however, as usual everything needs to settle for awhile. Changing the front 2 tubes on the EVO 400 preamp to Mullard CV4003 really helped the focus and take some edge off. The stock tubes aren't bad but this is where I was experiencing unwanted energy so to speak. The 150.8 has PLENTY of power and the needle doesn't even move so I am staying in Class A. Lots of depth and layering :)
