Accuphase has increased impressive skill in planning and building phono equalizers, either incorporated in preamplifi ers or accessible as choice (Promotion 2810 and Advertisement 20). Because of the desires of audiophiles around the world, we have now built up the C-27 as a top of the line standalone phono equalizer speaker, equipped for investigating the potential outcomes of the simple plate minus all potential limitations.
Thông số kĩ thuật:
