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.

do the power cables, you will not believe the difference!

This is almost universally agreed on.

When I changed out the stock PCs in my system the sound opened up to an unbelievable degree.

DIY VenHaus is a good cheap start

also Pangea Audio gets a few positive nods around here.

good luck and have fun

I agree with Philjolet. Just one word of advice...components with a low current draw such as a preamp do not need the heaviest gauge PCs.
For example, Pangea sells the AC-9 for amps and the AC-14 for preamps, CDPs, etc.
I also suggest you research the different types of power conditioners. With cleaner power, you will hear an improvement.

i own the pwd. while it "reads" 24 bit discs, it is an unremarkable component for 16 bit cds. Consider a replacement, unless you listen exclusively to hi resolution files or reference recordings dvds.
