Taken in trade from my customer who is Original owner who purchased New from authorized dealer about 6 months ago.
Absolute MINT condition. He traded only because he is combining 2 systems into one.
Original double box and packing
S6 employs three EL34 tubes per side, in parallel, driven in single-ended, Class-A triode mode. 35 WPC.
Gorgeous looks and sound to match (see excepts from a couple of reviews below)
If you’re new to valves and wonder what all the fuss is about, Unison’s Research’s S6 would be the perfect introduction. It sounds absolutely gorgeous, delivering that sweet glowing richness that tubes are famous for, without loss of bite or immediacy. Indeed, it’s the combination of silky smoothness and crisp immediacy that is so alluring.
Power output is limited, but the S6 is one of those tube amps that’s very good at covering its tracks. Listening to it, you’re rarely aware of its ‘limitations’. It recreates the music with little sense of strain and sounds as though it has power to spare.
LIKE: Rich, yet crisp, incisive sound – subjectively very powerful
DISLIKE: Runs hot – limited output power
WE SAY: Creates a big spacious soundstage with ample depth and width. Clarity is excellent; sharp, open and detailed
What Hi Fi - 5 Star Rating:
So good is the S6 in its areas of strength that we find it easy to forgive the lack of outright attack.
Rivals that can better it in this aspect don’t even come close in other areas. It offers a viable alternative to the established class leaders – one where the sonic character is so different from the norm that we can’t imagine a person being undecided in a head-to-head comparison.
So, then, if you fancy something out of the ordinary, and can take the care necessary to build a compatible system of suitable quality, this Unison Research amplifier is a simply terrific buy
