Soundlumia's Opinion

This is not a listing about audio tubes but an invitation for you to hear the sweetest voice on Earth. No other tubes can deliver vocals like the Mullard's, whether they're from Mitcham, Blackburn or Heerlen, and that's a fact. Before we get into the details of sound quality, let's be sure we are not talking about the regular Mullard E88CC tubes, but the very rare CV2492 military-grade tubes approved and tested by the British government, a HUGE upgrade from the garden variety.

"Like a warm British jacket of the finest tweed, these glorious tubes have an attractive sweet warmth in their midrange and lower regions." This is how experts on audiotubes.com describe the sound signature of Mitcham Mullard tubes. The top end is silky and pleasant and doesn't get rolled off. They retain a fine sense of "air" at the top, and the upper midrange is smooth and liquid. These tubes reproduce human voice, especially female voices, with haunting realism. Full disclosure from your peer audiophile: Mitcham E88CC's are my go-to tubes for listening to Maria Callas and Frank Sinatra and I refuse to use other tubes. Mitcham Mullard's are also known to have an attractive sparkle at the top with rich bass...now we know where that "warm British jacket" comes from!

"CV2492" is not just a label but a proud statement of British military-grade quality. The richness of the music reproduced by these tubes surpass any other previous attempt of any other Mullard E88CC's ever made. These are extremely low noise tubes, very neutral with pin-point tonal accuracy, providing an outstanding balanced and uncolored sonic tapestry that will put your mind in a whole new dimension.
