My original intention was to highlight the interesting quirks of the technology and possibly initiate some edifying discussion. That doesn't seem likely to happen. I'm sorry I got onto the issue of terminology - I just thought it was an amusing semantic quirk.

Yes, in as much as I have implied that a T-amp is not really an amp (i.e. not much), I am wrong with respect to conventional terminology. I'd still argue the T-amp is not -strictly- an amplifier internally, but since the end result is an amplified version of the input signal, it's reasonable to call it an amplifier. Hence: jimmyfergus Wrote: > Yes, for analog input, if you consider the unit as a whole, as with the > T-amps, it is arguably an amplifier in the abstract sense None of which indicates how a digital input with an analog output fits the definition of an amplifier. The Panasonic is not a class D amp. Its output stage resembles the output stage of a class D amp, but a class D amp takes, and processes, analog input and that crucial difference is what makes it reasonable to call them amplifiers. The Panasonic (TI PurePath) does not. There is no point internally where you could place an oscilloscope probe, even within a chip, and see a lower power version of the output signal. The only conceivable point where you can see a higher power signal matching a lower power input is in the digital realm - and that is achieved with switching, not amplification. If that is amplification, then so is every relay. -- jimmyfergus ------------------------------------------------------------------------ jimmyfergus's Profile: http://forums.slimdevices.com/member.php?userid=4323 View this thread: http://forums.slimdevices.com/showthread.php?t=33112 _______________________________________________ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
