|Music Preferences and Comments:|
|Music Used (Genre/Selections):||Female vocal, classic rock, jazz, classical. Complete collection of DCC Gold remastered CDs; all of the MFSL UDIs (Japan). My tastes have become far more eclectic since I bought the SACD player. 1000 SACDs but not growing now. I've been buying a lot of second-hand original CDs lately - made in Japan and West Germany in the '80s and early '90s. These sound better than the later reissues and remasters.|
|System Goals/Comments:||The Lamms replaced my Welborne Labs Laurel IIx SETs using WE300Bs. Not sure what to do with the Laurels.|
One day I will get the Vacuum State Electronics upgrade to my 5400.
I have a set of 6H30s for the BAT - but it keeps on going. I'll have to put them in one day, though.
