The Duo kit consists of 2 Mullard M8100 and 2 Siemens 5654W EF95 types for tube rolling in your Little Bear amplifier.
My recommendation is to use the Mullard M8100 for music where you want more midrange warmth or a more laid back sound such as Classical music, Jazz, Reggae or female vocals. For Rock Blues and Funk then I would use the Siemens 5654W as both these valve valves have a slightly different tonal signature.
The Mullard M8100 is very fast and dynamic with a deep warm bass response. The Mullard also has the smoothest and has the most detailed mid range response out of any EF95 valve that we have tested. The result is the most dynamic and enjoyable listening experience as they bring the music to life.
The Siemens 5654W is very neutral sounding and has a less pronounced midrange than the Mullard. So you get all the natural sound of the recording which many people prefer. Sonically these are a rock gem as they are a lot more punchy and upfront when compared to the Mullard M8100.
These are superb on Rock Music, put on Led Zeppelins Black Dog or Heartbreaker and these will lead you to the Stairway to Heaven. So In my view for Rock, Funk or Blues after hearing the Siemens this is the one.
The set consists of 4 valves
2 x M8100/CV4010/EF95 Mullard
2 x 5654W/EF95 Siemens
Please note that the kit is for the valves only.
