The choices in the poll span markets.
For the commercial hi-fi market, I think the preamp with integrated phono stage has the most potential. What would be great is to offer an option for a small Class D module to be integrated into the build. Something like a B&O ICEPower 125ASX2. Heresy, I know, but that is exactly what I’m planning to do with an old Foreplay kit that I’m building. There are so many user applications where a one-box solution makes sense. My own family room the adjoins our kitchen is a good example. It’s where we mostly hang out, but there is just enough room for a single Bottlehead chassis, and a turntable. And also, apart from the Jaegers, the speaker choices that are efficient enough to work well with single ended amps are few, esoteric and costly. It would be very nice to have a hybrid Bottlehead integrated that had the power to drive the inefficient speakers you see everywhere. I’d be surprised if such a thing didn’t become Bottlehead’s best seller.
For the pro market, no doubt that a tube mic pre would generate a lot of interest, particularly if the kit had some interesting build options, for example:
— For condensers, ~1.5k input impedance and P48
— For passive ribbons, ~65k input impedance with 70dB+ gain.
It would be nice to just have some sort of “ribbon mode†switch that would disable P48 and raise the input impedance. Bonus if it could have a variable input impedance control. Also, I would suggest that it should be in a 3U steel rack-mount chassis.
