Although some delay is inherent with AirPlay, the overall wireless bandwidth is critical for eliminating streaming delays. Have you verified the total bandwidth and data transfer rates for your wireless network to see if it is performing at its most efficient level?
Is your AirPort Express the only router in your network configuration or does your network employ multiple routers? When streaming is the iTunes host and the Express in the same room, different room, or different floor? If you do use multiple routers has are they located in relation to the iTunes host and the AirPort Express?

Thanks for yor response. Yes airport express is the only router. Both laptop and airport express are placed in the same room with best streaming efficeancy. I tried belkin bluetooth audio recevier instead of airport express and that works without any delay for sound but I want to use airport express for sake of simplicity and connecting my iPhone, Mac and speakers always connected. Do I need to possibly reconfigure Airport Express?

At this point I would recommend that you look for signs of Wi-Fi interference that may be preventing your Express from providing the best signal possible ... even in the same room.
An excellent tool to measure signal quality, built into OS X Mountain Lion, is the OS X Wireless Diagnostics:
- Option-click on the AirPort icon on the OS X menu bar.
- Select "Open Wireless Diagnostics..."
- Enter your Mac's Administrator credentials in the next window.
- On the Wireless Diagnostics window DO NOT click on "Continue." Instead, go to the diagnostic's menu bar, and then, select Window > Utilities
- Start the test with the laptop near the wireless router. Note the values for RSSI and Noise. They should both be negative and measured in dBm.
- Now take the laptop to the other locations that you want to access the Internet in your home. Different rooms, different floors, etc. Again, note these same two values at each of these locations.
- When you have finished collecting the data, you will want to enter them into the following formula for Signal-to-Noise Ratio (SNR). SNR = RSSI - Noise. For example, if your get the following readings: RSSI = -61 dBm and Noise = -84 dBm, SNR = (-61) - (-84) = 23 db
To get decent wireless bandwidth performance at a location you will want the SNR value to be 25+ dB.

Thanks I did the test. Values as per near to far in my usage area is ranging from 40+ dB to 25+ dB. I assume that is good?

Yes, these values should provide decent-to-excellent bandwidth performance.
