Warps And Listening
Warps are bad news no matter how you look at it. If the arm/cartridge remains parallel to the LP’s surface as with a flat record, VTA (Vertical Tracking Angle) remains unchanged throughout every rotation. Additionally, as the arm/cartridge tracks a warp on its upside, it places greater pressure on the stylus which changes VTF (Vertical Tracking Force) until the peak of the warp, whereupon the cartridge becomes “unloaded” with too little VTF on the way down.
Of course, all this muddles the sound, changing the tonal quality, imaging and soundstage characteristics of the cartridge. A flat record also tracks better with less distortion.
The DFV-1 doesn’t take up much room with its space-saving, vertical design. Improved film heating technology optimizes the entire heating and cooling cycle for a perfectly flat LP that your cartridge – and you – will love! Just unlock and open the DFV-1, place the LP on the spindle, close and tap a single button! An LCD keeps you informed of progress with a tone sounding when done.
“… After a session with the DFV-1, it was flat”
“… I found the DFV-1 Disc Flattener effective for banishing warps from LPs”
-- Michael Fremer, Stereophile October 2007
“…The Furutech DFV-1 performed exactly as advertised and I can say that I wouldn‘t change a thing about it”
-- John Potis, 6moons October 2007
“…The DFV-1 flattened any warped LP I threw at, no matter the weight or warping, and did so without damaging the LP in any way I could see or hear”
-- John Crossett, Soundstage September 2007
