Das sagt Audio Research: The SD135 is an entirely new amplifier for Audio Research involving a new mix of discrete devices within the framework of a pure analog, solid-state design. Like the larger HD220, the new SD135 (SD for Silicon Drive) uses Thermal Trak® self-biasing output devices in a Class A-B design. And like the HD220, it accommodates either single-ended or balanced inputs. But unlike the larger hybrid, the SD135 features an all-solid-state input stage using multiple JFET devices in each channel, directly driving the output stage – no interstage coupling capacitors needed. Because expensive coupling capacitors and high voltage regulated supplies required in tube circuits can be omitted, the SD135 is within reach of many more music-lovers. The SD135 is an amplifier with amazingly fast response time, explosive dynamics and plenty of current delivery for a wide range of speaker types including difficult, low impedance models. Frequency response is an amazing 0.4Hz to 300kHz! Bass is deep, controlled and quick to the punch. The noise floor of the SD135 is extremely low, rendering micro-dynamics and subtle sonic nuances with vivid clarity against a black background. Its presentation is transparent, detailed, and grainless – no listener fatigue here. Pair it with an Audio Research preamp and you will hear an immense soundstage in a highly refined and purely musical presentation. Reassuringly, the SD135 features protection circuitry that is sonically invisible. If there is DC at its inputs, or if its outputs are shorted, the SD135 will go into protect mode, muting the output and protecting your valuable loudspeakers. A low-speed (and quiet) 12V D.C. fan cools each channels internal heat sinks, helping to insure long, trouble-free life. The detachable power cord is a high quality IEC-type rated for 20 amps. The anodized front-panel is available with a natural or a black finish. Front panel handles are included but may be easily removed if the installation demands it. The SD135 provides the Audio Research hallmarks of high definition® and musicality in a compact, affordable package that will simply eclipse the competition. You must audition the SD135 for yourself to hear the latest evolutionary step in solid-state technology.

Audio Research SD135 solid state Amplifier. one of the best sounding solid state amps ARC ever made! This amplifier has had an important reliability modification done to it that keeps the sonic character but improves stability and long term reliability. for you tech types, PM me and I will be happy to discuss at length the mod. In Short, Onsemi the manufacturer of the output transistors came out for a short time with a version of a transistor that had an internal temperature sensing device that controls the amps Bias. that temperature sensing device fails and when it does the amp looses control of the bias and the amp fails. I have designed and installed a circuit modification based on what most class A/AB amplifiers use that adds an external temp sensing/bias circuit, but keeps the functional part of the output transistors working, but adds a new temp sensor for bias control. this keeps the sonic character of the amp as it is literally the same parts just with a more conventional bias control method. makes the amplifier far more reliable over the stock design.

Barely used and very good condition “The possible dream We know the dilemma. Sometimes the ear wants more than the bank account can deliver. And you're not a person who's willing to compromise. So it's exciting to find out the wait for your dream system might be a lot shorter than you might think. Cambridge Audio's Azur 351A integrated amplifier features all the legendary build quality you'd expect from their distinguished nameplate, and plenty of clean, reliable power for the most demanding music — thanks to the heavyweight toroidal transformer found inside its chassis.”“ (Crutchfield review) The Venom HC v2 is the descendant of the Venom-3 which The Absolute Sound voted as “One of the 30 Best Values in all of Audio”. The Venom HC v2 comes equipped with 10 gauge OFE power conductors for excellent current delivery. The fluorocarbon dielectrics are usually only found on much more expensive power cables providing clarity and excellent low level resolution. And the Venom HC’s pure copper contacts are unheard of at this price point. If you enjoy using iTunes® playlists or Spotify® streaming for your life's soundscape, the 351A has got you covered. And should you wish to add a turntable to your source mix, simply add a phono preamp in line ahead of one of the RCA inputs.
