[QUOTE="Veloce, post: 1117586, member: 16997"] Makes me actually wonder why you would need a pre-amp at all. All DACs can output more than enough Voltage for the specified full rated output of the power amps. So essentially your pre-amp is just an attenuator. Which is an unnecessary link in the chain, and for purists apparently less is more. So why would you want to add another item with its own sonic signature into the chain? If you feel the pre-amp adds something to the sound then surely that's just the added distortion or colouration you're enjoying? A pre amp with a frequency response is now just adding to the frequency response of the Power amplifier. So if they both have 20dB per octave of filtering, now you have 40 dB per octave. [/QUOTE]
