Cost model for building these has become prohibitive . The components are getting more expensive , capacitor banks , MoFets, etc . I suppose the China trade wars may be part of the problem. The upkeep and repairs on this unit will be fully supported , heard it right from Vinnie himself. I would think the unit may become more desirable for a certain niche . Some folks LOVE these units for ease of use and space consideration . I'm not an audiophile so to speak, more of a semiconductor geek . I am simply reviewing some "assets" I have.
