How would you rate the Rossini player with clock versus the Vivaldi without the upsampler?
The Vivaldi + Upsampler will beat it-but I would miss the clock. More weight on each note, ability to unravel the music a bit better, more air/resolution vs Rossini+clock. However the Rossini+clock is no slouch. In fact if you heard the Rossini + Clock I'd wonder why you needed more (until you hear the Vivaldi side by side). The clock will add sense of flow/pace, space, resolution, bass control and even better unraveling...so for a price, the Vivaldi keeps upping its performance level vs Rossini.
