A preamp are the “lungs”, the poweramp :”the heart”. Just like that. A good préamp,gives a beautiful signal to the poweramp. It means, it is very important. In a integrated amplifier is off course,the preamp very important.. the big advantage is:much less cabling. You cann't match like you want, because it’s from the same brand.
Is Pre-Amp needed
Is a preamp needed. I run my oppo 205 direct to an MC275-6 for two channel audio and it sounds good, but am wondering how much better a pre-amp would make it sound. A pre-amp seems necessary for multiple sources, but not for just one source. Would it just be an extra link in the chain or would it greatly improve the sound?
