Oh gee, I think this is the zillionth time I've written this. The D in class D does not stand for digital. It's D only because it came after 3 previous classes, A, B and C. And it's unfortunate it's an encoding format and class D because every one therefore assumes Dis is for digital. But it's not. There is an encoding and then decoding but the coding is ANALOG. Class D is analog. Sorry.
VTV D300 Digital amp
Very similar to the Peachtree GaN 1 but with more power and bigger power supply....Nice WBT jack option. Nothing to say about the sound, as yet....as this is just now being released and none have been shipped. But.....this thread is ready when someone gets one and can chime in with their findings. Just like the Peachtree, this one only has coax input.

And I will write this over and over: a "digital amp" is not a normal class D amp. It is an amp that takes a digital only signal (PCM) and converts it to a PWM (class D type of switching) signal and then the class D output stage sends the signal to the speakers. So, you have regular class D.....usually with op amps on the input and lots of feedback......that is as stated above by dynamiclinearity...not digital at all....it is analog switching.....and THEN you have a digital amp which is what I just described. Regular class d amps need a DAC in front of them to decode the digits......a digital amp IS THE DAC and the amp all in one.....big difference. There are no analog stages or feedback in an digital amp.....The limiting factor on sound is the software written on the DSP chip that does the conversion, jitter, clocking, switching frequency and purity of parts and power supply. These EAS boards are great.....but, I am sure we will see all out implementations of this technology within 3-5 years (will cost way more than these boards!!!). This is the blow away the $20K systems teaser board......the blow away the million bucks systems boards are coming later. What a fun ride! |
