The new Cara preamplifier ($3,500) is a remote-controlled dual-mono and two-chassis (it has an external power supply) box, wrapped up in steel. Neat feature ? Cara will let you ?normalize? your volume by input. That is, if you have a source that tends to be a little quiet, you can give it an invisible and pre-set bump to bring it up to the level of the rest, or/likewise, you can knock down one of your louder sources to come back into line. Plus or minus 12dB is the range there. The pre has a 115dB range (max), and an SNR of 110dB/THD of .002%, and presents a?100k? input impedance/50? output impedance. The display, which has a variable brightness, is big and easy to read.
