what else do i need to improve sonic performance?

I firmly believe that all the basics should be done right, which means power cords should be upgraded, than you can make an informed decision - imo

I would not change any equipment until you do this, I think you may well forget a need to upgrade/change

Mrtennis I dont know if you are talking about the Perfect wave DAC or the transport?
I have to be honest i feel more satisfy with teh sound coming out of the hegel HD11, back and for i tried so many times, maybe is just synergy with rest of the gear.
my room is around 5 meters long by 5 meters wide, but is sort of triangle shape, at the begining i hated but the sonics improved i guess was more psichological about the structural shape.
Maybe I am biased coming from full range speakers with amazing Dymanics as the AZ crescendos and Ayon triton amp, I was told by Paul from Tube USA that when you tried a 120 watts class A tube amp its hard to get satisfaction with less, but so far Luxman/harbeth is a very pleasant surprise
so the reviews and forums were right cause i bought them without havent listened, due to geographical circumstances and no dealers around with teh products.
I am missing dynamics and the cymbals of Pat Metheny group coming trough in the way we like, but certainly an amazing midrange to die for.

i will keep reading advice about power cables and power cleaner plants, maybe i can look into a cartridge upgrade on my rega P5.
Vinyl sound is keeping me closer to analog this days,
even with an excellent computer/DACs combo, i can be listening to lps whole day, Cds, get fatigue quiet fast what is a shame cause i have a lot of great music.

I cant thank you enough for your responses,
thank you all.

I would advise against spending money on ultra expensive wire, but you wouldn't listen, so what's the point. The fact that you asked the question says you want to buy something.
Cheers.

There's many different ways you can upgrade your system. A couple of people mentioned going with new power cords. I agree that they do make a difference. The one thing I would recommend, though, is to try the cables in your system before you buy them. In many cases, power cords don't make a positive difference. If you don't have a good local dealer that you can use, I would definitely call The Cable Company. They can send you a bunch of different cables that you can demo first. I have been using them for years and have been very happy with the results.

One other thing you may want to consider is upgrading your phono cartridge. I had the 10x5 and thought it was a great sounding product for the money. If you step up to the Dynavector 20x2. I did and think it was well worth the money. If your phono pre can handle it, I would get the low output version.

I have de ps audio phono that I forgot to mention.
Plus the luxman built in one.
I will call the cable company!
I will also look into cartridge upgrade, I think its the weakest link on my system today.
