The Portable Micro uses a custom battery with a center tap so we do not need any rail splitter or similarly functioning circuitry.
A very good preamp is able to deliver the signal from multiple sources with authority to whatever load is presented. The load presented from a headphone is much worse than what is potentially presented by any power amp. I'm not sure how a 'preamp' is really any different except that it could be simpler. It could be as simple as a passive switch depending on your system. This thing has the potential to deliver much more with the addition of the DAC. Feel free to elaborate on this as I don't know how I would make the preamp outputs any different. Maybe I'm not understanding the point?
Thanks for your comments and questions. I'm sure most of them will be answered when your package arrives.  Don't hold your breath though... |
I completely agree about the preamp. It's just a nomenclature thing. I was just wanting to clarify that there is nothing different about the signal path to the 'preamp' socket on the back then there is in the signal path to the 'headphone' socket on the front, and that they are in parallel and thus what is connected to one effects the other by altering the load on the circuit - is that right?
I'm still not quite with you on the PSU - by dual cell, do you mean that each cell is running at 7.4V and then run in series with its neighbour to make 14.8V per battery? And for the portable micro, does that mean it is running at +/-7.4V?
If that's right, I'd be very interested to hear how this battery arrangement compares to your DPS/internal PSU's with the same electronics. Experience tells me it might actually be better...
When are you expecting to post info on the rest of the new Micro line?
