I have both the TAD-150 preamp and the TAD-1000 mono block amps. I am running a pair of Martin Logan Aerius i with them. It drives my speakers VERY well. The TAD-1000's are a far step up in quality from the Cayin TA-30. I know I will not be upgrading my two channel for quite some time. I am really enjoying the TAD stuff. I have had the monos since Christmas, they are definitely broken in now.
