Soundstage was definitely something I felt was weird with mine out of the box, it had an off-shape to it and had a lot less frontal depth than width... But keep in mind, these amps are somewhat unique in that they had less than 10 hours (maybe less than 5?) of burn in after manufacturing. There is a DEFINITE burn-in period and noticeable change in the sound as you put the hours into it. Educational! Now the soundstage space is much more even and extended with a smoother sense of roll off to where the soundstage "ends."
Nice pic, I actually quite dig the purple color cast! I wish I had spent time with the earlier version prototype of the Spark at RMAF, but I confess I was more interested at the time in hearing the LC which I'd ordered and been waiting on (can you blame me?). It was also Cavalli's booth where I really stopped to get a handle on what each of the high-Fi or Summit-Fi headphones sounded like, with quick swaps of Sennheiser, Audeze, MrSpeakers, and HiFiman headphones on the same Cavalli LC + DAC (aurelic Taurus? Or something?) audio chain. Alex was SOOO kind to share the time. Please say HI to Warren (and Alex, is he there?) for me!!!
My opinion, if the Spark continues having the same DNA as the LC and LGold, the Spark may well be the obvious upgrade after the popular Objective2 amp, taking the O2's quest for transparency and value further with less distortion/noise and less coloration on reactive headphones (like Sennheiser) because of it's current-mode amplification (in addition to near-zero output impedance). Ask Warren if the Spark also has more power in reserve than the O2 design?
Hope you're having an awesome time at CanJam! Wish I could be there too!!
