Balanced Audio Technology (BAT) is a decades old company specializing in, you guessed it, balanced audio components. They have produced a long line of vacuum tube and solid-state preamplifiers and amplifiers, phono preamplifiers and, more recently, digital converters.

The original B.M.C. Audio MCCI phono preamplifier earned very positive reviews when it was introduced in 2013. Carlos Candeias used his designs for the $1400 Aqvox Phono 2Ci, reviewed here on 10 Audio, and introduced a much-upgraded model as the MCCI under his own brand, B.M.C. Audio. The MCCI ($3890) was replaced with the MCCI Signature ($4298) in 2016.

The Wyred 4 Sound STP-SE line stage preamplifier was originally introduced in 2009 and has been gradually updated and improved over the years. This latest, top of the line model includes many parts and technology that we find in cost-no-object preamplifiers from some of the most respected and expensive brands.
