Any one can explain How will be the noice/jitter level while playing laptop as the transport? Is there any other way to play the music to avoid such problems.
Very difficult to predict. Connecting your laptop to a Benchmark DAC1 would be a solution if you suspect you have jitter.
Jitter is common but not always audible. Random jitter is the least audible. Correlated jitter (related to a signal of some sort) is much more audible. More than 250 psecs is roughly the threshold where it can become audible on most music when it is random (but many people might not hear it until it got to 1 nanosec). For correlated jitter it is probably much worse and some have suggested as low as 20 psecs (but of course it all depends very critically on the frequencies involved and many types of correlated jitter may not be audible so easily). Correlated jitter seems likely when you have electronics, data and a spinning transport involved.
Benchmark DAC1 is around 7 psecs - it seems very much designed around eliminating the jitter problem but that is no help unless it works well (synergy) with your speakers.
