Kenwood L-07MII

1 9 7 8 1978
1 9 8 0 1980

TRIO in Japan, Kenwood elsewhere - the big-little monoblock.

Price-wise at the lower limit of high-end separates in Japan : a Yamaha B-2 cost 200,000¥, a Sony TAN-8550 285,000¥, a Luxman M-4000 350,000¥ ; a pair of L-07M cost 200,000¥...
Sound-wise, however, the L-07M was near the upper limit of most power amps !

Updated in 1978 as L-07MII, with a skyrocketing 600Khz frequency response and a smaller sibling (L-05M) and an x-rare bigger, much bigger brother (L-09M).
All high-speed, all very very tight, controlled and linear.

The L-06M variant is a late 1980 unit, fairly different in looks and design as it sported the Sigma-Drive circuit - even tighter :)

Replaced by the futuristic-looking L-08M in 1980/1981.
