Anthony Gallo Reference and many other speakers were developed (voiced ) using Spectron amplifiers. For many years, Mr. Gallo displays his speakers at CES, RMAF and similar hi-fi shows only with Spectron amplifiers. So it is not a "brainer".
Moreover, Spectron amplifier has very high input impedance - this allows you to match it with any preamp including best tube preamplifier. BAT is truly excellent, Joule-Electra, my favorite, preamps were voiced along with Spectron and thus there is synergy between Joule-Electra,. Spectron and Gallo
If you choose other transistor amplifier like Nuforce you mentioned - check its input impedance for matching with tube preamps in future
All The Best
