“Beautiful sounding tube. Great detail overall (Especially the midrange), but not via an over-emphasized treble range, as can be the case with some audio equipment. Good extension at both frequency extremes, but definitely not a "U-Shaped" profile. Midrange is beautifully warm. It's a tube that makes it hard to stop listening to music for hours on end!”
