what else do i need to improve sonic performance?


Luxman 550 A II
Harbeth Compact 7 ES3
AZ Hologram II
Rega P5 DV 10x5
Hegel DAC HD11
PS audio PWD
Nordost LS RD

Wondering if I change stock power cables and get power plant cleaner, how much could improve the sonics, certainly I am a novice in the hobby, and always reluctant to spend money in power cables and so on, in fact always used stock pieces,
really appreciate your help.

What dont you like about what you're hearing? You have some amazing gear. Your amp and speakers are a well known match. What stands are your speakers on? How far away from the walls? Hard woods or carpeting?
