I use its little brother the 5300 LPS in animation since 1987 almost 600 animations without ever having been any failure
these are really rolls of sound
the lps 5300 developed the bench in 1986 when I bought 2x 275 occas Watts RMS into 8 ohms

I use it since 1988 with 1200 hp mac kenzie
including 800 rms

it does not calle
I'm always careful not to saturate the red LED

it's really one of the best amp
