Based on the newest Russian tetrode KT-150 S.A.Lab Blue Sapphire Integrated is the state-of-the-art integrated amplifier of really fantastic — boundless musical capabilities.
According to S.A.Lab’s motto music is the way it is for Blue Sapphire Integrated. Nothing but music…
Highest degree of musical expression and realism, raw energy and sharp graphics of dynamic macro- and micro-relief, perfect whole frequency spectrum control beginning from deepest lows to ultra-highs, subduing naturalness of timbre, spacious acoustical drawings and rarest combination of sound athleticism and musical aristocratism are the main and incontestable Blue Sapphire Integrated’s advantages.
Blue Sapphire’s heart or most important part is unique output transformer produced by Alexey Syomin’s hands especially for this project by using high quality iron from South Korea. Each channel transformer’s weight is 12 kg (24 kg in total). Designer has decided to utilize the newest Russian tetrode KT-150 (Saratov) as output tubes solely after finishing the work on output transformers.
There are four KT-150 in push-pull design (two per channel, one at a shoulder). To make the most out of KT-150 engineer have had to provide high voltage at the tube’s anode: 650 V. According to S.A.Lab’s philosophy as applied to company’s highest quality tube masterpieces the separate anode heating transformers are used for KT-150. Two 6072 (Saratov) work as input tubes, four 6F6 (NOS) are implemented at the driver stage.
High quality audiophile electrolytic capacitors Epcos are used; other capacitors and all resistors are made by Mr. Syomin’s hands from selected wire and graphite.
Armour-like sculptural plywood chassis (much the same as White Knight and 300B SE have) is painstakingly decorated by high gloss black lacquer and 10-mm deep blue sapphire glass sheets.
Anybody who shut a cursory glance on Blue Sapphire Integrated and listened to the amplifier’s bewitching voice will never forget his strong impressions. Humans call such the sensual experience as «memorable». While listening to music with S.A.Lab Blue Sapphire Integrated it is hard not to exclaim «amazing!», «inimitable!!», «marvelous!!!»
