708P應該就是來取代6328P的型號，但708P貴大概四百美元，所以比較像進階版。
供參
1.進階係性能進階？功能進階？價格進階...等，皆有所別。
2.708P是否成為6328P進階款，尚需經由更多地客觀的性能測量、主觀的聽評進行綜合性評價，倘僅以價格為憑說，在嚴謹性易不足。
ex.(以下採官方公佈之data，簡示一二例)
(1)FR
6328P: 50Hz-20kHz (+1, -1.5 dB)
708P: 41Hz-25kHz (+/-3 dB)
6328P: Low Frequency Extension: User controls set to default
-3 dB: 46 Hz
-10 dB: 36 Hz
708P: LF FREQUENCY EXTENSION (-10dB): 35Hz
(2)HF/LF AMP
6328P：
HF : 120W Class A-B, monolithic ;
Sine Wave Power Rating: 120 watts (<0.1% THD into rated impedance)
THD + N, ½ Power: <0.05%
LF : 250W Class A-B, all discrete;250 watts (<0.1% THD into rated impedance)
Sine Wave Power Rating: 250 watts (<0.1% THD into rated impedance)
THD + N, ½ Power: <0.05%
708P:
HF : 250W Class D
LF : 250W Class D
(3)Distortion
6328P：
Distortion, 96 dB SPL, 1 m:
Mid-High Frequency (120 Hz - 20 kHz):
2nd Harmonic: <0.6%
3rd Harmonic: <0.5%
Low Frequency (<120 Hz):
2nd Harmonic: <2%
3rd Harmonic: <1%
708P:
0.1%THD @ 1kHz/2.83VRMS output;
<0.5% THD @ 1kHz, Full rated output
PS.
在官方6328P已停產停售之際，當然希望有個比它更佳的新系列進階款可選擇。
