Top of the line. Cary 211M mono amplifier, used pair in excellent condition original crates and double boxes. Photos are without tubes but you get those packed separately. It is well known that using monoblock amplifiers, as opposed to both channels together as a stereo chassis, is the best way to get powerful and lifelike music. By using separate power supplies that can be much more massive, each amplifier can have more dynamic power and be quieter. Keeping two separate amplifiers also makes any inter-channel crosstalk in the amplifiers impossible, so separation is better, meaning your soundstage and musical imaging will be larger and more well-defined. The simple act of separating the two channels provides a lot of distinct advantages, but also increases the investment because of needing to double up on power supplies and chassis parts. Learn More

small profile package utilizing huge internal heat sinks to support Class A, balanced, and Krell Current ModeTM topology • Evolution CASTTM, voltage balanced, and singleended inputs. Evolution CAST, which stands for Current Audio Signal Transmission, is a proprietary method of sending the audio signal between components in the current domain, from a high impedance transmitter to a low impedance receiver. Krell components connected in Evolution CAST act together as an electrically unified whole, free from the deleterious effects normally inherent in connecting cables operating in the voltage domain. • Low feedback topology; only 8 dB of nested local feedback utilized. No global feedback is used. • Push-pull output stage with 10 pair of ultra high speed, high current, output transistors• Push-pull driver stage configuration resembling a miniature output stage This unique circuit actually powers the speaker load when the audio signal is at the zero-crossing point. Notch distortion is effectively eliminated, maintaining the benefits of Class A operation with the efficiency of an A/B design. • Massive 3 kW torroidal transformer, four 35 amp bridge rectifiers, and 110,000 microfarads of filter capacitance, ensure ample current under the most demanding circumstances. • A second low current transformer stabilizes voltage for ultra-quiet operation. • Internal high current line conditioning circuitry filters RF noise on the AC Mains and compensates for asymmetric power waveforms and DC on the AC Mains. Protection circuitry continuously monitors all amplifier operations. • 12 V trigger controllable We can Change it to your desire voltage Learn More

The conrad-johnson design team is committed to adapting the advances from our state-of-the-art pursuits to more affordable offerings accessible to a wider range of music lovers. This resolve is clearly evident in our new range of Classic amplifiers. Borrowing heavily on the technology of our flagship ART amplifier, the Classic amplifiers preserve the distinctive tonal character of individual instruments and voices, with each clearly located within the overall acoustical environment of the original recording. Musical transients are reproduced with realistic impact, but without artificial enhancement. Like their more costly siblings, the Classic amplifiers capture the emotional impact of the live event, never getting between the listener and the musical performance. There really is no mystery to our chosen path to outstanding musical performance: best results come from simple circuits executed with quality parts. The circuit design for the Classic amplifiers is about as simple as possible, employing just seven vacuum tubes in the Classic Sixty-Two. Single-ended triode voltage gain and inverter stages are coupled to an output stage comprised of a single pair of ultra-linear operated EL34 tubes for each channel. The Classic One-Twenty adds a second pair of output tubes to each channel to achieve twice the output power. Simple but highly effective discrete voltage regulators supply rock-solid stable DC voltage to the critical voltage gain and inverter stages. And speaking of simple, maintenance of the Classic amplifiers could hardly be easier: the owner need only make a simple bias adjustment using the built in bias indicators when installing fresh output tubes. The use of premium quality component parts is the other half of the conrad-johnson recipe for superior musicality. In this area as well, the Classic amplifiers are leaders in their class. Precision, metal-film resistors yield low noise performance for greatest clarity. Polypropylene and polystyrene capacitors, chosen to achieve a high degree of temporal accuracy, are specified for both the audio cir¬cuits and the regulated plate voltage supplies for the input and inverter stages. The result is an exceptional range of dynamics – reproducing both subtle variations in level as well as dramatic loud crescendos. Our proprietary trans-spectral wide-bandwidth output transformers contribute importantly to the extended, “airy” highs that help distinguish the Classic amplifiers from ordinary tube amplifiers. The base model Classic amplifiers offer an ideal introduction to the joys of modern tube amplifiers, while the ease of use, low maintenance costs, and reliability will be a revelation for those who have only experienced “entry-level” tube gear. Those who wish to take the experience a step further will want to investigate the upgraded Classic Sixty-Two SE and Classic One-Twenty SE amplifiers. These special edition versions upgrade the output tubes to KT120s and incorporate CJD Teflon Capacitors and ultra high-performance metal foil resistors in strategic applications in the circuit. Any of the Classic amplifier models are sure to rekindle your passion for enjoying great music in your home. Learn More

Almost no use, this is the top of the line Stax headphone amplifier in the original double box The SRM-T8000 is STAX new designed top-of-the-line driver unit. For the first time in STAX driver unit history, the large-sized toroidal transformer and non-magnetic aluminum chassis have been adopted for unclouded clear tone quality! A newly developed large-sized aluminum insulator, combined with new material of high isolation efficiency and grip power, make this flagship designed SRM-T8000 a top performer. Features: • The full-balanced transmission of hybrid amplifier configuration with 6922 dual triode tube of established reputation for the first stage and class-A operating semiconductor at output stage realized ultra low-noise, accurate and rich musical expression. • The vacuum tube of the first stage was mounted on the independent board in order to shut out vibration and external noise. Further, noise has been totally eliminated by vibration-proofing damper and vacuum tube shield cover which are used also for a hard disk etc. • The large-sized toroidal transformer - for the first time in STAX driver unit history - as well as non-magnetic aluminum chassis has been adopted for unclouded clear tone quality. • Four pairs of inputs are equipped. (Notes: LINE4 is an optional slot for future purpose. As for now, release is not yet determined.) • The SRM-T8000 features the EXTERNAL (BYPASS) function which passes the volume controller of the unit and enables volume control through external equipments. • The newly developed large-sized aluminum insulator, combined with new material of high isolation efficiency and grip power, has been employed.
