Anyone using Joule Electr VZN100 MKIII amplifiers?

I´m considering the purchase of a LA150/VZN100 combo to drive Merlin VSM-M speakers in a small listening room. Any detailed comments about sonic quality of this system will be very appreciated (please, only people who has really heard it or own it...I´ve read all the show reviews but I really need first hand comments). What´s about the noise level with this preamp-amp combo? Is the combo really silent dead? If not, how much noise can I expect?
TIA.
