Steve,
I currently have a Transporter (source) and Metrum Octave (DAC).
Without going to a new DAC which product would offer the best improvement to the above setup?
Syncro-mesh?
Pace Car (Mode 1) with Ultraclock upgrade?
Something else?
Also on the different pages of your website you mention a Superclock4, Turboclock and Ultraclock...could you clarify which one is actually the "best" and why these clocks aren't an option on every product?
