Pass x250.8 vs Boulder 850 vs Spectral DMA250


Hi all, I sold my old integrated amplifier (Vitus RI-100) and now I have a C2550 mcIntosh Preamplifier.
Next month I will have the possibility to make an audition on these amps, some of them are second hand so the resulting price will be more or less comparable:
- the new Pass X250.8 (I am afraid about what I read on burn-in hours required)
- Spectral DMA 250
- Boulder 850 monos
my intention is to drive my Sonus Faber Elipsa Red with a very good slam/control (where Vitus RI-100 lacked) but without loosing the excellent Vitus mids/highs.
Anyone experienced ? Any other suggestion will be appreciated.
Thanks
Massimo

I suspect the Boulder amp to be better sounding!, this is based on preference like anything else, The Boulder has very good Transparency!, A member named Melbguy1 can chime in on this subject, He knows alot more than I do about Boulder equipment.
