Welcome to my Analog Audio Web Site


Aside the wide popularity of CD as a medium in mass consumer audio, there is an obvious increasing demand of LPs and LP players. More and more serious audiophiles are going back to LP for digital reproduction is often perceived artificial, cold or harsh. Other listeners simply notice a loss in the music’s soul and ability to transfer emotions when comparing LPs and CDs.

Given comparable amounts of money, a LP system can easily sound better than a CD system. Furthermore numerous vinyl recordings from the sixties and even the fifties still set standards in artistic performance and audio engineering. Hence despite the introduction of SACD and DVD, the analogue technique is celebrating a comeback.

All projects presented on my site underwent intense modifying, testing and listening by members of the Klangforum Dresden.

Have fun with the schematics and please send me an e-mail for comments or critics. Any feedback is greatly appreciated.
