I bought Marantz PM-7000 few months ago, i fed up with the sound quality of this amplifier, it just sounds really thin, some details in the midrange are really missing. No matter how high the volume i turn up, but still i can't hear some of the details from midrange. I feel really frustrated especially when listening to R&B and dance music.

Does anyone using Marantz PM-7000 Integrated Amplifier? Any opinion?

I'm thinking of changing it to Cambridge Audio Azur 640A, any opinion?

My system:

Acoustic Energy AE120 Speaker
