Howdy Audiolabyrinth, thank you kindly for your comments. Per your comparison. Amps & preamps are quite diff from cars. Cars rarely are tested after they've been produced: big production numbers with limited testing results in some lemons. Amps and preamps typically are thoroughly tested after they've been produced: small production numbers with testing should weed out the few lemons. Furthermore, to protect consumers, most states have automobile lemon laws. For audio components, consumers rely on the whims of manufacturers.
My Atmasphere amps and preamp were purchased new direct from the factory. The preamp with its reversed diodes, overheating resistors, and other issues was a lemon. Calling my Atmasphere monoblocks lemons is being kind. The matched amps were so different internally they appeared made by diff people in different years. In a scary fashion, each amp emitted profuse amounts of smoke. The smoking cure (not the cause as someone implied) was to replace, under the factory's direction, resistors in the amps with those of a different value. On-going problems were numerous. It's possible one amp was a prototype which would explain the vast differences in the matched amps.
As mentioned previously, during my ownership of these products, including the warranty period, the factory did little to rectify problems. Even the unmatched matched amps were deemed suitable, as I recall as appearance had no bearing on functionality.
