Phaelon,
Great idea, I think you're definitely on to something.
I can't think of a better company to expand/perfect your concept and make it a reality than Atmasphere. I bet they could start brainstorming design possibilities Monday morning. It'll probably take until the end of the year to build, test and evaluate a few different design prototypes, however.
Once the best prototype is determined, it'll probably take approx. 6 months to work out parts' sourcing, costs, pricing and marketing strategy.
Then another few months to determine and document a Bill of Materials, manufacturing instructions and QA procedures.
So, all told and if there are no stumbling blocks, it may be possible for the first lot of Atmasphere's game changing Hybrid Tube-Class D amps to roll off the production line sometime by the end of 2014 or beginning of 2015.
Ralph,
As I'm sure you know,I'm just having a little fun. I'm watching the final rounds of the NFL draft and there's a lot of time between picks. However and FWIW, I think lot of people would love this to become be a reality.
I even have a marketing slogan idea:
"Same great quality and performance of Atmasphere,
Just with a less heated atmosphere."
If you ever do decide to build this world-beater amp, please pm me when you're ready to send me the production prototype for in-home testing.
I won't charge you for the testing but I won't pull any punches when I post my review here on Audiogon, either.
Thank you
Tim
