With all of the talk in the Marantz 30 product about Denon Alpha processing, Denon just announced their new 110th Anniversary products which really do seem like new versions. The integrated AMP is very different from the PMA-2500NE
"The PMA-2500NE used a one-stage amplification with a high-gain amplifier, while the PMA-A110 adopted a new two-stage configuration with a variable gain preamp and a power amplifier. By incrementing or decreasing the gain of the preamp according to the volume, the noise level can be dramatically improved by amplifying only the power amplifier without amplifying the preamp within the range of commonly used volume."
Interestingly, when the PMA-2500NE came out, they said that the one-stage was better
"Murayama: First of all, we stopped the two-stage configuration of the conventional flat amplifier and the power amplifier, and adopted a high-gain amplifier that amplifies 45.5dB at a time. As a result, the number of elements and circuits passed through was reduced, and the route was able to be greatly shortened, so the configuration became simpler."
The second interesting part is that it's introducing new ULTRA AL32.
Ultra AL32 Processing utilizes data interpolation algorithms and supports Hi-Res 192-kHz/24-bit PCM signal input. These algorithms interpolate points that should exist before and after the points in large quantities of data to achieve a smooth waveform that is close to that of the original signal. These algorithms up-sample the bandwidth from the original content, smoothing out the waveform and improving the sound reproduction. Ultra AL32 Processing doubles the processing bandwidth from the previous generation up-sampling 384-kHz/32-bit content to 1.512-MHZ.
