New high resolution SACD releases, players and technology.

bi-amping is a more important issue even if you

don't have a subwoofer or two... or more.

Many years ago (long before audiophiles ever thought about multiple channel systems), several audiophile publications were pointing out the real advantages of having a subwoofer in your audio system.

Aside from the fact that a quality subwoofer might provide you a deeper reach into the depths of music, a system composed of subwoofer(s) that are fed through a quality crossover and its/their own amp(s) can actually provide the listener with better sound throughout the sound spectrum. The reason should be obvious: if the amplifier used to drive your main pair of speakers is not called upon to provide the entire sonic spectrum it doesn't have to work as hard. So, if you chop off the bottom octave or two and send them to another amp for the bass, the dynamics of the signal it now sees makes for a less arduous task.

Therein lies another benefit to subwoofers: since most audiophiles would agree that transistor amplifiers recreate bass better than tube amps do, but many believe that tube amps sound more like real music over a broader range of frequencies, you can have the best of both worlds by having a tube amp run your main speakers and a transistor amp running your subwoofer(s).

In my own stereo-only system (I'll consider multi-channel when the creator sprouts 3.1 more ears on my head), I have two subwoofers crossed over at 85 Hz with a 6 dB slope, so my transistor amp (150 watts) is just poking along. My main speakers have 90 watt tube amp poking along too.

All this talk about subwoofer outs on receivers is therefore needless, as my system will play any stereo SACD without the need to make any adjustments.
