Any advise to improve my system


My current stereo system consists of the following:

Sony DVP-9000ES
Plinius CD-LAD pre-amp
Plinius SA-250 MkIV power
PSB Stratus Silver-i Speakers
Harmonic Tech Pro-silway II RCA from DVD player to pre-amp
Harmonic Tech Pro-silway II XLR from pre-amp to power
MIT MH-750 shotgun speaker cable
Synergistic Research Reference AC Master coupler for CD player
Synergistic Research AC Master Coupler for Pre and power amp

My music preference are string instrument, vocal, jazz.

I always feel that I don't get enough kick from listening to my system. It is either not enough detail or bass extension is a little muffled.

Any advise on what is wrong with my system?

I would start by switching from Harmonic Tech to Acoustic Zen, they are about the same price. I have had all Harmonic Tech cables and Nordost SPM and Quattro Fil, as well as NBS Monitor 2. My system just got right with the Acoustic Zen cables, Silver Reference interconnect and Satori Speaker Cable.
Speakers I agree, but I would try balanced Ic between CD and Pre-amp if the DVP has the feature.
One word: Q-tips. Try 'em and tell me I'm wrong.

If you're not too attached to your speakers, here are two options you might try. For supreme detail and transparency, consider electrostatic speakers. I've been very impressed with Martin Logan CLS IIz's. But bass isn't their forte. For a great speaker top to bottom with a slightly laid-back presentation, consider Talon Khorus' if they're within budget.

Maybe a dedicated CD player (Sony XA7ES?) could offer some slight improvements. I've also heard of aftermarket modifications that can be performed on the 9000ES that are said to be worthwhile. Good luck with the system.
