Reviews & Awards

"The NSEQ and TCL2 are the most pure, clean, clear, transparent, and natural music sounding EQ and Compressor ever!"
Kip McGinnis, Bardstown Audio

“We’ve been using our [eight channels of] TCL-2 Twincoms for a number of stereo and six channel surround mastering projects with great results.
The ability of each unit to sound either as transparent as the Class A solid state electronics or as warm as the vacuum tube electronics is a big advantage. The Twincom has become our reference analog dynamics mastering processor.”
Bob Ludwig, Gateway Mastering & DVD

“The Millennia Media TCL-2 sounded nothing short of fabulous on voices (especially male voices), guitars (electric and acoustic), and most
keyboards. It does a great job of controlling the dynamics of sustained, high energy programme material, and it bestows interesting dynamic
effects on more transient audio. I was often surprised that sources I expected to benefit from the valve amplifier chain actually worked better with the solid-state path, and vise versa.”
Hugh Robjohns, Sound On Sound, UK

“The Millennia Media TCL-2 is an amazing dynamics processor. The subtle differences between the two circuit topologies allow me to be much more precise when choosing the appropriate character for a signal, and the purity of the signal path preserves more of the original signal than any other compressor I’ve used. This is the way that high end audio equipment is supposed to be -- well designed, well built and with a wonderful sound.”
Dave Martin, Audio Media US Magazine

“This is a clean, great sounding compressor. The two topologies both sound pure, transparent, and, in most circumstances, remarkably similar, with the J-FET circuit sometimes marginally more detailed.... For the purist, this is a good value, high-performance compressor.”
George Shilling, Studio Sound Magazine, UK

“The TCL-2 is beautifully constructed and is as sonically neutral as anything I have heard.”
Joe Palmaccio, Senior Recording Engineer, Sony Music, NYC
