Best Integrated Amplifiers — McIntosh, Octave

Integrated Amplifiers

McIntosh, Octave, MBL and Burmester — one chassis, without the compromise the format usually implies.

An integrated amplifier used to mean accepting less. At this level it does not.

Putting preamplifier and power amplifier in one chassis removes a pair of interconnects and a set of connectors from the signal path, and lets the designer match the two stages to each other rather than to an unknown partner. The argument against was always power supply compromise and noise — which is an engineering problem, and these are the companies that solved it.

There is also the practical argument. One box, one power cord, one remote, and a rack that does not dominate the room. For a great many systems that is not a concession — it is the better answer.

Fewer boxes, fewer connections, less between you and the recording.

How to choose an integrated amplifier

At this level an integrated is a genuine choice rather than a compromise — one power supply, a shorter signal path, two fewer cables. You trade upgrading in halves for a better result per dollar. Check what is built in first: a good onboard DAC or phono stage changes the comparison entirely.

Choosing an integrated amplifier, in detail

An integrated is a preamplifier and a power amplifier sharing a chassis and a power supply. The old assumption that this means compromise stopped being reliable some time ago — at the top of the market an integrated from a serious manufacturer will beat separates from a lesser one, and it removes a pair of interconnects and a second power cord from the signal path.

What you give up is the ability to upgrade one half at a time, and headroom at the extremes. What you gain is a shorter path, one box, and usually a better result per dollar. If the system is likely to stay as it is for a decade, an integrated makes sense. If you expect to change loudspeakers upward, separates leave more room to follow.

Check what is built in before comparing prices. Many current integrateds include a DAC, a phono stage, or both — and if those are good enough for your use, the real comparison is against separates plus the boxes you no longer need to buy. If they are not good enough, make sure there is a clean analog input to bypass them.

The comparison worth making is an integrated against separates at the same total price, on the same loudspeakers. We can set that up directly, and the result surprises people often enough that it is worth the hour. McIntosh, Octave, MBL and Burmester integrateds are all on demonstration.
