catman Posted July 30, 2016 Share Posted July 30, 2016 G'day all, keeping phono preamp noise low has been a long time interest of mine and I am now lucky to have two MM phono stages that are very quiet, the Rothwell Audio 'Simplex' phono stage, and the excellent Akitika PhonoZ DIY phono stage which uses a very clever 'miller loop' circuit approach to reducing the phono stage input noise. Daniel Joffe of Akitika has just written an interesting article on this 'miller loop' noise reduction approach. It's very interesting and works very well. http://akitika.com/documents/ElectronicCooling.pdf. Regards, Felix. Link to comment Share on other sites More sharing options...
