in the Cambridge audio azur 640a i am hearing the sound quite well , but the middle vocals are not prominent and there isn't a good nature balance sound (when the Direct botton is in on) .
i cant swiching the trible button to low level. and when i swich on the volume bottun just a little a hearing a huge sound ... this amp doesnt suit to rock music...i think so. my qustion is , if i will buy the nad c352 will i be notice to the differences? i need an answer from someone who already heard the two amplifiers!? and by the way, i bought this amp. cause i saw the excelent Specifications : in azur 640a : 0.01% THD @ 20Hz - 20kHz Frequency Response: 5Hz to 50kHz +/- 1dB and in NAD C352 it's less impresive detailes: Rated distortion (THD 20Hz-20kHz) 0.03% Frequency response 20Hz-20kHz ±0.3dB thank you. amir
