@cycles2 There definitely will be many new things to obsess over in 3-4 years, probably 1-2 and again 2 years after that, again after that and so on and so forth!
The Rossini clock made an improvement in my Atlanta-based friend's system however his system overall is very high end and resolving in terms of speakers, amps and pre-amp spend. That stated it was not an earth-shattering improvement. If you want a Word clock that is compatible with your Rossini DAC, I'd suggest the Esoteric G-02X; it has reasonable price, better build quality and a full OCXO implementation. This is all opinion mind you. It also allows for a 10 Mhz input 50-ohm for future upgrading. I think it will deliver a more pronounced improvement. It's Word clock outputs at 75-ohm and have a wide varieties of WCLK frequencies to utilize to find the best match;
