Re amps with balanced inputs


Is it true that some are not truly a balanced design? Like Rotel for example.....or Anthem......
does anyone know for a fact Bryston and Mccormack are truly balanced designs like a Krell FBP or a BAT? THX

Hope this helps.
Music Reference RM-200 has balanced inputs only.A hybrid SS/Tube design.The best of both worlds +.A Great Modern sounding Tube amp.Punchy bass and silky detailed mids and highs.
Check out the K ohms of impedance at the inputs.
In a truly balanced design the balanced inputs ohms
is probably about twice the single ended .And yes
the Anthem is not truly balanced but the Sim audio is
on the W-3 and W-5 .
