i guess the general sound signature remains the same(which i really love by the way! very precise and farward sound and warm when the music needs it)
but i would like to know if there is improvements in sound . and if it could be felt not only to high sensitive audiophiles listeners.
thx, an already satisfied customer!

The biggest differences are at the power supply level and in the quality of the potentiometers. The Desktop Power Supply gives you most of that goodness, but in the Home there are dual supplies, separate for each audio channel for greater purity and channel separation.
In the larger amps the potentiometers are also better (the standard Nobel and Alps are good, and the Stepped Attenuator is excellent). These are slightly cleaner sounding to my ears, especially the SA, and have better matching between the levels of the two channels (again, especially the SA).
There are very minor differences elsewhere but the above components make up most of the difference.
