Tubes are back, and in a big way.
Most audiophiles have, at one time or another, considered purchasing a Class A amplifier, but the cost was prohibitive. A preamplifier, you have the makings of platinum sound, through and through. For those of you too young to know what a tube looks like, or have succumbed over the years to discarding the old tube amp for solid state, your ears are in for a pleasant surprise. The single ended variety of amplifier is actually the oldest design there is. Now, of course, power amplifiers of the push-pull type, both tube and solid state, are available with hundreds of watts of output per channel.
