I've owned both the Sonic Euphoria and currently use the Modwright 9.0SE. The Sonic Euphoria is very good but I consider the Modwright a clear step-up. Most amps like a little gain which was the case with my Quicksilver V4s. The midrange is fleshed out better with the Modwright and the bottom a little more authoritive. However, and this is a big however, you must use a very good power cord with the Modwright or it too will sound veiled. When you figure in the cost of a new power cord the price will be significantly more than the Sonic Euphoria. Frankly, I wouldn't use the PS Audio Lab II on the Modwright since I doubt you would be happy. The BlackSand Silver MK V or VH Audio Flavor 4 are excellent choices with the Modwright.
