I love the concept of a "defrost" cycle on your preamp. But I would like it for burning in the preamp or warming it up quickly before a listening session.
In our industry/hobby we can either advertise features or sound quality. Advertising bells and whistles seems more like the approach for the masses. For those of us participating in this forum "microwave marketing" likely doesn't have much appeal. Microwave marketing espouses the objective qualities of an item. Advertising subjective qualities (such as sound quality and its many aspects) is a different marketing approach entirely. Having been in a position over many years to find effective ways to advertise subjective qualities, I must say it's not easy. Most manufacturers in this industry fall on platitudes to present the sonic aspects of their products. Platitudinal descriptions are something that every brand could use in equal measure. How then do you describe a unique subjective sonic quality of one product that doesn't apply to another brand as well? Marketing in the high end of this industry/hobby is a challenge.
