DR-3 POM/ER AMPLIFHER

Distinct from countless amplifiers which appear and often disappear on
the audio scene, our third generation Pure Class A power amplifier continues to prove
itselfa refreshing musical experience. The supert1 sonics ol the DR-F are not simph
the result olstrictiv applied Class A techniques. The} ' stem also from a! thorough under-
standing ol'audio power with respect to real-lite, loudspeaker loads. This " Ithj ll 'tr
time listeners ol'tlie DR 3 are alien shocked at its cupatity to outpiav implitiers liming
four or more times the power. it is also curious to note that the Dix 7 is rarely coni-
pared to other low or medium powered units. Rather. it is put up against the best sourt
ding super power amps on the market!

Audio power is comprised ol'two parameters: voltage and current. While voltage
is relative-iv simple to develop. current is not as easill' afforded. and much less so In
(lass A amplifiers But the DR 1 is uniquelv capable otdeiiveritig as much HMS output
current as voltage. while prol mg more ot'that current in Pure Cl is A.

The finest components available are meticulously assembled into 3 DR 5. wherein
lunctional [zoom and elegance are exemplary. Dual-mono throughout. each channel
begins with a powerhouse 350 m transtornicr and 55 Amp bridge rectifier. toilowed
