Cary Audio SLP-05 and Parasound a21+
The SLP-05 is one of the best sounding preamps on the market and features a stand alone power supply box with low noise R-core transformer. the main unit uses glorious sounding 6SN7 and tube rectification. Spend the extra money for the heirloom preamp and buy a top value power amp in the Parasound a21+.
Call me crazy (but I am not) because I like the sound of the a21+ more than the JC5 and Pass Labs XA30.8, both of which I owned.
The a21+ is transparent, powerful, clean and dynamic and one of the best values in audio.
