thx thx very much,I have many questions and dont know how to describe with my poor english. No.1. if we select Digital output（SPDIF or COAXIAL）,Yamaha NP-S303 and V681 does the same thing,is that correct? No.2. if No.1 is correct ，when we plug them to A-S501 with digital signal input ,then S501 do the DAC works,and then output to Speakers,the awsome sound depends on S501,is that correct? No.3. if No2 is correct,can we replace the Network player （S303 or V681）with PC，using Digital signal（SPDIF or COAXIAL）output to S501，and then output to Speakers,does the sound close to No.2? No.4 if we select Analog output to S501 using NP-S303,then S303 itself do the DAC works,and if DAC in S303 is better than DAC in S501,is the sound better than No.2 or No.3?

thx so much！ so many questions come. Speakers,AVR,Player,which is important? I decide to buy a new Yamaha network player NP-S303 ======================================================================= S501: Minimum RMS Output Power (8 ohms, 20 Hz-20 kHz) 85 W + 85 W (0.019% THD) High Dynamic Power/Channel (8/6/4/2 ohms) 130 / 150 / 185 / 220 W Frequency Response 10 Hz -100 kHz +/- 1.0 dB Total Harmonic Distortion (CD to Sp Out, 20 Hz-20 kHz) 0.019% (50 W / 8 ohms) Signal-to-Noise Ratio (CD) 99 dB (input shorted, 200 mV) ======================================================================== so,the player NP-S303+ HiFi Reciever A-S501+the speaker RP-160M,does the music sound awsome? do I need to buy a Network player or just use the V681?because the NP-S303 cost $382 dollars if I buy it from Amazon japan ,and V681 cost $411 dollars in my city. and using V681 I can upgrade my HT. what should I do for the music?

thx for answer my question，and I want to ask another question，does this AV V681 fit the hifi Reviever ，can it make great sound with RP-160m，do i need to switch to Yamaha A-S501

half time for music ，half time for movie，and this speaker is for music

Speaker RP-160M: FREQUENCY RESPONSE 45-25kHz +/- 3dB SENSITIVITY 96dB @ 2.83V / 1m POWER HANDLING (CONT/PEAK) 100W/400W NOMINAL IMPEDANCE 8 Ohms Compatible ===================================================== Yamaha RX-V681: AV Receiver Amplifier Section Channel 7.2 Rated Output Power (1kHz, 1ch driven) 150 W (4 ohms, 0.9% THD) Rated Output Power (20Hz-20kHz, 2ch driven) 90 W (8 ohms, 0.06% THD) Maximum Effective Output Power (1kHz, 1ch driven) (JEITA) 150 W (8 ohms, 10% THD) Dynamic Power per Channel (8/6/4/2 ohms) 125 / 165 / 190 / 235 W who knows ? if not match ,how should I change the AV Receiver ?
