For SS, give a listen to the Vitus Audio, either their Signature series or their Reference series, and some Tidal and Soulution stuff if you have access to them. They are phenomenal.
The Parasound Halo JC1 or the new JC5 are bargain considering their performances and are highly recommended. The recently discontinued Classe Delta CAM-600 class AB monoblock amps are also spectacular and can be had at discounts nowadays. Some higher end Naim amps are very musical and has very good rhythmic drive and are special.
