CAMBRIDGE AZUR 651A/B INT.AMP

At Cambridge Audio we don't believe in gimmicks. Instead we like to invest in components that really make a difference to the sound you hear. That's why in the 651A, we use a premium toroidal transformer which is key to its unruffled performance with music of all types.

Adding to the audiophile specifications are separate transformer taps for left & right channels, twin rectifiers and separate PSUs for dual-mono operation of the left and right power amplifiers. Meanwhile a high grade film type volume pot means the 651A also performs as well at low levels as at higher volumes.

Whatever hi-fi speaker you choose, the 651A is designed to drive almost any model with ease. Our retuned output stage featuring Sanken output transistors gives excellent bass response and dynamic control.

We all like to crank up the volume from time to time and our proprietary CAP5 system ensures unrivalled peace of mind against overloads, faults and clipping.

Meanwhile, connection support for analogue sources like CD players, iPod docks and tuners is better than ever so whether you store or stream music from your computer, iPhone or maybe you prefer the luscious sound of good old vinyl, the all new Cambridge Audio 651 will make all your music sound amazing.
