By from Greymouth. , New Zealand on
I am no expert but have owned several amplifiers over the years of varying quality . I recently acquired a CA-400 2nd hand but hardly used very cheap.
I connected it to my beloved Rotel RA-870 BX pre-amp
and wired my pair of 250 watt RMS speakers to the
CA-400 power amplifier which promptly delivered
Tons of power to the speakers with crisp , clear sound .
I would be interested to have it tested to see if it actually
meets it's claimed 700w RMS in bridged mode but I have
no question about its claimed THD of 0.05 .
I think my CA-400 is an excellent addition to my sound system . Quite a refined Beast !
