The Virtuoso line of amplifiers are our medium line of amplifiers, they won't be the last word in sound quality or design, but they will have a few smart compromises to still make them reasonably priced. Generally speaking they will be in line with many other professionally priced amplifiers. These will not be entry-level amplifiers but they will be designed for very good quality for the money, both sonically and physically. In this line to a very limited degree, we offer to customize an amplifier for the customer, but not so much that the design is entirely unique but slightly altered for a reason. Adding some changes will require a charge per item changed.
