Telefunken CV2493=E88CC/01 - Ulm 1960s

CV2493, Telefunken, Ulm, diamond bottom—this combination deserves your full attention. The rare military version of the E88CC/01, the CV2493, usually appears under Mullard labels, occasionally under Amperex, and almost never under Telefunken. This Soundlumia exclusive presents one of the rarest tubes in the world. With exceptionally low noise, carefully matched triodes, rigorous batch testing to military specifications, and shock-resistant construction, these tubes demonstrate Telefunken’s authority in ultra-high-end tube sound.

Experienced listeners of Telefunken E88CC tubes will find the following three NEW sound characteristics on CV2493 very appealing: 

1. Enhanced midrange presentation. The recessed quality that some listeners hear in Telefunken tubes, including the CCa, is replaced by a fuller, more forward presentation that feels warm and intimate. If the Mullard 10M Master Series demonstrates that a tube can be both musical and analytical, the CV2493 approaches that balance from the opposite direction: analytical first, yet distinctly musical. 

2. The CV2493’s bass is best understood through microdynamics—the fine-scale precision with which an effect begins, develops, and decays. Rather than hearing each bass impact only as a finished event, you can follow its initiation, descent, impact, harmonic trail, and final disappearance from the soundstage.

3. For listeners who enjoy the holographic soundstage of the Telefunken E88CC, the CV2493 offers an even more immersive and encompassing presentation. Instead of sitting several rows back, you are placed at the center of the stage, surrounded by sound.
