Review of TDSS Upgraded

I have had the opportunity to listen to the revised NuForce Ref-9 amps and I like them a lot (see picture). In addition, I have also compared them to other amps I have just for some auditioning fun. It seems to me that their sound character remains the same but they sound is more robust, especially in their ability to control the big woofers on my Wilson Speakers. Also, gone is the annoying clicking/swoosh sound during on/off, which helps create a feeling of better quality.
Thanks for your work,"
