There's nothing wrong with wanting better quality parts, but there's also nothing really wrong with the components on the Masi. A mix of Tiagra and 105 is a very functional setup that could easily get you through numerous SR series without changing anything. Well, except maybe the saddle.
But if you really want a similar rando style bike with better parts, you generally have to build it yourself. Find a frame you like and start collecting parts.
The other option is to get something like the Masi, Volpe, Cross Check, Raliegh Clubman, etc. and start replacing parts with better quality little by little. Of course, by the time you get all the parts you want, you'll probably wish you had a better frame.
