For sale is a STAX SRM-007 tA Vacuum Tube Energizer. Normal 0 21 false false false BG X-NONE X-NONE The SRM-007tA (also known as SRM-007tII on the EU market) is one of STAX flagship driver units, intended exclusively for earspeakers. Its a fully balanced Vacuum Tube amplifier, that features four 6FQ7/6CG7 dual-triode valves and three inputs (one XLR and two RCAs). The ultra-light polymer film (only a few microns thick) realizes unprecedented response and a high degree of resolution. Since it is driven on all sides, there is almost no partitioned vibration and there is no phase distortion, nor any imbalance in the sound quality. If you are trying to get the best out of STAX top of the line models (SR-007 or SR-009), look no further. The unit Im selling is in excellent working condition. It has been professionally converted from 100V to 240V (essentially making it identical to an SRM-007tII), so no additional transformer will be needed. Visually, there are some marks and scratches (as visible from the photos), but nothing major that affects its perfect performance. Comes with its original Electro-Harmonix tubes, but no original box (Ill make sure to pack it extremely well). From a pet free, non smoking home.Will dispatch it tracked and fully insured either the same, or the next working day. Economy (via GLS) and standard (via DHL ground) shipping usually takes about a week, while Express delivery via DHL (air shipping) arrives in 1-2 business days (please dont pay attention to eBay estimates - they are assigned automatically and theres no way to edit them). In some cases, standard service might actually be cheaper than the economy one, so do pay attention at checkout.Condition and serial number are documented and recorded, so scammers - dont waste your time here. Please purchase only if you have 10+ feedback, or contact me prior placing your order. All of my perfect eBay feedback comes from selling expensive headphone gear, so buy with absolute confidence!Feel free to check my other listings as well. And last but not least, thanks for looking!

Stax SR-007MK2 Headphones & SRM-007T2 Energiser (Kimik) 3 month warranty Stax SR-007MK2 Headphones & SRM-007T2 Energiser (Kimik) 3 month warranty Superb STAX Electrostatic headphones complete with valve energiser. Both are in excellent condition and full working order. They come with original headphone case and our usual 3 month warranty. STAX Say…. STAX SR-007MK2 Headphones The rationale is the development of the new SR-007MK2 Earspeaker was to provide deep powerful sound previously unobtainable in Earspeakers. STAX engineers developed a unique new electrode structure. Visible through the outer case, gold plated on the outer edge this new electrode has no holes unlike conventional STAX Earspeakers and thus provides an increases diaphragm vibration area allowing for rich and powerful sound yet retaining all the delicacy STAX is famous for. Specifications: Type: Push-Pull electrostatic circular sound element, Open-Air type enclosure Frequency Response: 6 – 41,000Hz Capacitance: 94pF (including cable) Impedance: 170k ? (10kHz) Sensitivity: 100dB / 100V RMS 1 kHz Bias Voltage: 580V DC Left & Right Channel Identification: ‘L’ and ‘R’ indicated on the cable entrance point, solid line (left) and dotted line (right) on the cable Ear Pads: Genuine Lamb Leather (direct skin contact), high-quality synthetic leather (surrounding portion) Cable: Low capacity wide format, PC-OCC (Pure Crystal Ohno Continuous Casting) 2.5m/8.2ft Ambient Temperature & Humidity: 0 to 35ºC / 90% max. without condensation Weight: 12.9oz without cable / 1.1lb with cable STAX SRM-007T2 Headphone Amplifier (Kimik) The operational principle of the electrostatic condenser type is based on a system whereby plus and minus output signals are input by push-pull into two electrodes sandwiching a diaphragm with a high level of accuracy and equidistantly, resulting in the vibration of an ultra-thin membrane through the repulsive force and suction force of static electricity, which is then converted into sound. The balance method, which is considered to be the ideal for amplification, is thus extended to speakers. The electrostatic system entails input by balance, output by balance, and sound conversion by balance, and, in realizing all these features, constitutes the perfect balance system. It is the only system that makes it possible to listen to sound in the ideal manner permitted by the balance system. The new SRM-007tII is our flagship model of a driver unit intended exclusively for Earspeakers characterized by their wide range, high dynamic range and outstanding operating features with full allowance made for SACD and other new-generation high-density formats. The ultra-light polymer film, only a few microns thick, realizes unprecedented response and a high degree of resolution. Since it is driven on all sides, there is almost no partitioned vibration and there is no phase distortion. Nor is there any imbalance in the sound quality of the unit or distortion caused by the network. Electromagnetic distortion also does not occur. It opens up on the world of high sound quality that is the mark of headphone listening, a world characterized by the absence of need for large output, the high degree of freedom permitted by the use of high sound quality elements for use with small signals, and the even balance between left and right unaffected by acoustic conditions in the listening room. Features: ? We’ve taken another look at circuit constants and achieved a higher grade of reproducibility for SACD and other new-generation audio formats. ? Consists of a pure balanced amplifier in which the XLR balance input does not have to pass through a transformer, an inversion amplifier, etc. ? Makes use of a simple two-stage amplification structure based on rigorously selected low-noise FET. The load resistance makes use of non-inductive coil resistance manufactured by Dale, thus realizing straightforward properties that take advantage of the features of vacuum tubes and outstanding sound quality with a high level of clarity. ? The output stage is designed to lower impedance by using a rigorously selected high voltage dual triode (6FQ7 type) in parallel connection, which has resulted in an improvement in dynamic range especially in the high frequency. ? The heater power source for the vacuum tube makes use of a power circuit of the DC ignition type using an electrolytic condenser and a high-speed Schottky barrier diode, bringing about further improvements in the SN ratio. ? Makes use of a large-capacity power transformer and capacitor. ? Equipped with one XLR (balance) input system and two RCA (imbalance) input systems, meaning that there is a total of three input systems. ? In the case of the RCA input, switching with the earth side ensures that there is almost no interference between devices. ? Use is made of a high sound quality quadruple volume unit which makes possible XLR input as well as all kinds of line level analogue voice inputs. ? The RCA terminal “Input 1” is equipped with parallel output terminals and enables input throughout. Connection with other pre-amplifiers and recording decks, etc., is also possible.
