BACKERT LABS RHYTHM 1.4 LINESTAGE TUBE PREAMPLIFIER
The Rhythm 1.4 is our flagship preamplifier. It looks just like the Rhythm 1.3, but it sounds…. better. Silky, powerful, dynamic, and huge. Backert Labs finest linestage tube preamplifier
Features
Fully balanced XLR inputs (2) and output (2): for those of you with long cable runs or who feel that balanced XLR just sounds better.
Incredibly long tube life: Our proprietary five-step design process for the gain stage extends the lives of your tubes, to the point where they might just outlast all of us.
Brass: We have found that incorporating a solid-brass bottom panel to support the unit (and the circuit board) provides more holographic and more natural sound quality.
Dual-mono power supply: left and right channels have their own power supplies and regulators and their own separate windings in the power transformer, for the ultimate in separation, imaging and accuracy.
Highest-quality output capacitors: The highly seductive V-Cap ODAMs handle output duty. These are not PTFE, because we find that this material is best suited for the demands of the power supply. To our ears they are extremely revealing, involving, accurate capacitors.
“Crazy-good” power supply capacitors: the famously dominant V-Cap PTFE capacitors now drive our GreenForce power supply — with copper foil, these exotic capacitors are unheard-of for use in an audio power supply. In any any power supply at all, actually.
Improved circuit board: features design upgrades that improve grounding and separation throughout.
Improved stock tubes: our special NOS tubes provide maximum pace, dimensionality and resolution.
Our latest circuit: last but not least (because it’s probably the most important point), the Rhythm’s gain stage and power supply regulator designs benefit from our latest research.
