My most important tools are my ears and my 15 years of mastering experience.
In my opinion, analog mastering is still the best and most musical approach to achieve warm, impactful sound with audiophile quality.
 I use high end analog tools by Avalon Design, Sontec, Manley Labs, API, Tube-Tech, Smart Research and NTP. Most of them are modified to my taste and to exceed their original specifications. I rely on unsurpassed Lavry Gold and DCS AD/DA conversion and Lipinski monitoring with Magis amplification. The signal path is kept very short with selected cabling to retain the highest possible transparency.
