This is in response to the original post of Niodari. I have the same setup but for power amplification I use M700 monoblocs. For my digital front I have the DirectStream with Bridge II, and for my analogue front I use two turntables with PS Audio's Stellar Phono Preamp. I enjoy listening to Jazz and Classical.
Before considering a new amp, may I suggest looking at interconnects, and speaker cables as well as the incoming power line for interference from any transformers / adapters that are connected in parallel. I would start with the power conditioner and the devices that share it with the pre - power combo.
One of the options you may want to test-drive is Van Den Hul The Second in XLR format. Linear Carbon has unique audio characteristics. Once you have exhausted the possibility of improvement with interconnects, you may wish to test-drive your speaker cables. There reasonably priced very good cables from AudioQuest, Tellurium Q, QED, Black Rhodium, and Chord Co.
