    Includes Phono Stage


    A beautifully-crafted, hand-made tube piece manufactured to deliver the sound of the classic Marantz 8B. The A-50T MK 2 now features the ability handle either EL34 or KT88 output tubes.


    The Cayin Audio A-50T MK 2 uses four EL34s for Class A/B1 P.P amplification but can use KT88s (not included) if so desired. The craftsmanship is absolutely first-rate, featuring point-to-point wiring, and each unit is hand-initialed by a quality-control inspector. The toroid power transformer and EI audio transformer are specially manufactured for the A-50T MK 2 with low magnetic leakage, wide frequency response and low impedance. Two 12AX7EHs and two 12AU7s are used in the preamplifier. One very cool feature is the ability to switch between ultralinear and triode by remote control.


    This piece was hand-built with extreme attention to detail, including point-to-point wiring. Point-to-point was the way that amps used to be wired back in the 1950s and '60s when cost was not the primary objective. Nowadays, most everything contains circuit boards instead of this point-to-point wiring, which is much more dependable and better performing. The bottom line is that point-to-point wiring sounds better. It's one of the main reasons why these Cayin pieces sound like the classic tube gear from Marantz and McIntosh. Anymore, products that feature point-to-point wiring cost a fortune, or they feature sub-par workmanship. You simply are not going to find craftsmanship like with this Cayin gear for anywhere close to this price.


    There are output taps for 4 or 8 ohms. This allows you to fine-tune the sound that you desire. Switching is simple, and listening to the differences is a lot of fun. There is a removable cage, included at no extra charge. The cage snaps into place simply, so that you can take it on and off with no problem. Keep it on if you're worried about protecting your tubes, or take it off to show what real, heavy-duty, classic tube gear looks like. Turn off the lights and watch 'em glow.

    It was quiet, and golden-sweet and liquid in the midrange, as you'd expect from a 12AX7-based phono preamp.

    - Michael Fremer, Stereophile


    The vp130 is a tube phono preamp with a built in headphone amplifier for use with moving magnet and high output moving coil cartridges. The vp130 is designed to amplify an RIAA equalized phono signal to a hi level signal. Since the unit utilizes tube circuitry the resulting output signal is more warm and musical than solid state preamplifiers. The real kicker aside from the price and stellar sound is that it's manufactured in the US.

    The story behind the Valve Isis


    Rega's now legendary head electronics engineer Terry Bateman spent 10 years researching the concept of a CD player using valves in the output amplifier.


    When it came to the inspiration for this project Terry drew on the enormous experience he gained while working with musical instrument valve amplification, which dates back to the middle part of the 1970's. Terry's concept was based on the need to have a playback chain, which is in harmony with the instruments and equipment being used.


    Valves have been widely used in musical instrument and recording amplification from the 1950's to the present day, therefore it made great sense to develop a valve based CD player to match that of the signal chain found in such applications.This approach kept the circuit straightforward, this is mainly because musical instrument amplification is not excessively hindered by some of the folklore surrounding certain aspects of valve audio design. He took the approach of combining the technical and sonic attributes of valves in a differential instrumentation amplifier circuit driven from differential output DAC with a passive LC filter.


    Careful choice of valves and the use of moderate levels of feedback keep the distortion at reasonable levels thus keeping the colouration to a minimum. The valve Isis became fully realised when he combined the valve project with the Wolfson high performance differential output WM8741 DAC along with the digital playback circuitry of its solid state stable mate.


    Design


    The valve Isis shares the same digital and USB sections as found in the solid state version however the analogue stage is valve based with passive filtering. This stage uses two military specification triple mica 5814A (ECC82/12AU7) triodes being driven by the revolutionary Wolfson WM8741 ultra high performance digital to analogue converter.


    The output buffer and transformer driver stage uses two ECC88 (6DJ8/6922) triodes. This, like its solid-state stable mate, is of an un-orthodox design. The design goal with this player was to keep away from the normal design approach of lets run it through a valve to make it sound warm, but take advantage of industrial valve circuits to make an articulate and competent valve based CD player. Careful choice has been made for every component in the digital and the analogue signal path to ensure the integrity of the signal.


    Careful design of the PCB's ensures isolation of not just the digital and analogue sections, but also the motor, display and user interface processor. All sonically critical electrolytic capacitors have been by-passed with polypropylene or polyester film capacitors. In addition to this, large value electrolytic capacitors have also been by-passed with audio grade electrolytic capacitors. Power supply impedances in the digital to analogue converter are kept very low by the use of solid polymer capacitors. All power supplies utilise custom Rega K-Power smoothing capacitors, and fast diodes have been used throughout in power supply rectification.


    The Isis uses enhanced and optimised control code for the control of the CD processor and user display; this will speed up the initialisation process by means of a tighter control interface between the user micro and CD processor.


    Technology


    The differential output of the digital to analogue converter drives a valve differential (operational) amplifier, with a very modest amount of feedback to stabilise the operating conditions. The 5814A based differential amplifier, with a solid-state current generator in its tail, takes full advantage of the differential output from the digital to analogue converter. This is followed by a passive Butterworth second order LC filter. Finally, this signal is buffered using a low anode resistance ECC88 to drive the output and balancing transformer.


    In design it was felt that unnecessarily high levels of THD would unduly overwhelm the qualities of the digital stage of the Isis. The overall THD is typically 0.06% being prominently even order, where the 2nd harmonic predominates. This will give the sonic dynamics of the valves without dominating the sonic qualities of the digital section.


    After many hours of tube rolling we found the 5814A differential amplifier position was best on the grounds of micro-phonics, reliable operation and sonic qualities. Both the HT & LT power supplies are fully regulated and use the same power supply parts as used in the solid state Isis. Like the solid-state analogue stage valve Isis has it's own dedicated 50VA mains transformer, ensuring galvanic isolation between the digital and analogue sections of the player.


    The Isis has an isolated balanced output, and in keeping with the spirit of the valve circuit topology we have opted to use a transformer in this position. This balancing transformer is made to the same exacting standards to that found in the IOS MC amplifier.


    We hope that you enjoy this product as much as we have enjoyed creating it. - Rega


    All these features amalgamate to create the supreme level of performance found in the Isis and provide a perfect partner for the Rega Osiris amplifier.

    Heart Of The iTube2


    First Time Ever To Select SET, Push-Pull or Classic


    Both Analogue Signal Processing Circuits New And Improved


    ELNA Silmics And TDK C0G Capacitors


    The original iTube became the 'go to' tube buffer for any and every home audio system. We have redesigned the micro iTube2 with new parts and new circuitry using trickle-down technology from the flagship 'Pro' series. Only the GE5670 tube remains.


    The micro iTube2 is a tubed output stage, tube preamp, tube buffer AND an impedance-matching device all in one. There is nothing like it. You can put the micro iTube2 before a solid-state preamp and another one after it, creating the effect of tubing the whole audio chain. Or you can choose to simply use the micro iTube2 as a very high-quality preamp by itself.


    The micro iTube2 sounds by and far, like a tube amplifier 'done right with the inimitable magic of tubes.' Tonality and heft, especially in the mid-range and bass frequencies are increased to elevate the whole audio chain - regardless of whether it's a $1k or $100k system. The micro iTube2 injects a serious does of tube magic into any audio system.

    AmpsandSound Products Are Handmade In Small Batches and Go Through Extensive Quality Control


    The Casablanca's are aptly named for their classic good looks and commanding performance. They came about in response to repeated requests for a single-ended amp with the power to drive non-compliant or inefficient speakers. Given that large power SE amps are either run in pentode or using exotic power tubes, Ampsandsound opted for a push-pull based amp; a larger version of the Stereo 15.


    The Casablanca's provide 60 watts with KT88/6550 power tubes, and 45 watts with EL-34s. Based on the Eico circuit and using a 12AX7/6SN7 front end allows access to a vast array of NOS/NIB tubes. The Casablanca's come with 8ohm and 4ohm taps and can be ordered with 16ohm taps if desired. To provide reliable power and a sweet sound, they turned to their design partners and carefully evaluated 2 new takes based on similar designs; the Eico HF97 and the Dynaco MKIII. They built both and did a shootout with the reigning king of push-pull amps, the McIntosh MC275.


    The results were startling. The Eico based circuit was a clear improvement over their take on the MKIII, and was on par with the MC275. The Casablanca's provided extremely articulate bass, with truly remarkable mid and high frequency extension. The bottom line - this amp provides the warmth and detail that is expected from reference level push-pull amps, and nearly limitless personalization with different tube combinations. The tubes included with purchase are new Tungsol 12AX7, Tungsol 6SN7, and Tungsol 6550s.


    They were recently asked what differentiates Ampsandsound Casablancas from any of the other well-made gear in the $2000-$3000 range. The answer is that there may be few differences, but the differences that do exist are pivotal to their approach to the reproduction of music. First off, many tube amplifiers in the Casablanca's price range have lower power. Other similar-price amplifiers are stereo amps, not providing the performance and channel separation for which mono-blocks are known.


    They chose the Casablanca design to allow for the largest practical power supply. Also, mono-blocks require 40% more parts, and like all Ampsandsound components, the Casablancas utilize modern materials to bring a higher level of performance. This includes using 1-2% resistors instead of the less costly and more common 10% variety, and coupling capacitors with 5% tolerance instead of 20%. Point-to-point wiring would allow for streamlined building, but their PCB's provide superior grounding and noise isolation, with the result that they have realized and improved upon the sonic characteristics of the great amplifiers of the 50's and 60's.

    Designed Over A Lifetime And Hand-Made By Peter Ledermann


    10 Year Warranty



    The HE-150 amplifier's design is the result of nearly 40 years of research in solid state amplifiers with the goal of building the most transparent and most reliable design possible. Years of investigation into why most solid state amplifiers cause listening fatigue and often cannot be listened to at all power levels has yielded tremendous results - a highly linearized, Zero Feedback lateral MOSFET amplifier ~one that has been called the most fatigue free sounding, tube like circuit ever made. Although it has the warmth associated with tube designs, it also has (unlike tubes) ultra low distortion and is free of the colorations that tube amplifiers cannot avoid. Being solid state, it does not degrade over the years requiring constant expensive feeding of new tubes and other components due to heat damage. It is unique in the industry, and always solicits comments about how it disappears.....after all, an amplifier should not get in the way or be noticed.... except for its absence in interfering with your listening.

    Like many AmpsandSound products, the Mogwai evolved from their earlier designs, borrowing from the Bigger Ben and Classic Wonder, while embracing the form factor of the Kenzie. The Mogwai offers more than an entry point for tube amps, but a hybrid product, meant for both headphone and loudspeaker use.


    Their circuit offers the ability to roll a wide variety of tubes inexpensively and bring increased power to headphones without any sacrifice of design choices that conflict with our values.


    The Mogwai combines the features of a full-sized two-channel power amplifier and headphone amplifier in a chassis that is suitable for a desktop use.


    The Mogwai utilizes single-ended Class A operation with zero feedback to provide the essence of our Classic Wonder sound; strictly old school SET sound, without having to spend hundreds if not thousands of dollars on tubes.


    The performance of the Mogwai is made possible with custom wound ultra-high quality output transformers from Transcendar, which provide excellent frequency extension and a flat response.


    The Mogwai does not use a voltage divider network, but depends on transformers instead. They chose a 32 ohm tap for headphones to offer a dedicated selection for the widest range of headphones, and an 8-ohm loudspeaker tap to connect the Mogwai to moderately efficient loudspeakers.


    The Mogwai displays its transformers prominently on the chassis to frame in the tube compliment, which can vary from a 6L6GC to a KT88.


    Volume control is handled by the ALPS volume pot to allow attenuation and simplify the signal path. Zero feedback on the outputs negates the need for a pre-amplifier; an iPhone can drive the Mogwai without issue.


    The Mogwai differs from the Kenzie as it aims to provide powerful output while remaining true to classic tube design. As with all ampsandsound products, they strive for a neutral, non-fatiguing sound, and demand that all our products be ultra-quiet in operation. Quiet operation is not just a goal but a guiding principle that shapes all design and implementation choices.


    The Mogwai is handmade with pride in Southern California with US-sourced parts, including our precision transformers.

    The draw of single-ended amplifiers has always been a level of engagement that other amplifiers often fail to deliver; well designed single-ended amplifiers are not only impressive in the midrange, but across all frequencies.


    The Bigger Ben is designed to offer transparency, rich detail, and an incredibly low noise floor. Parts selection was crucial during the design process and each was chosen not for price, but for the level of synergy between parts. Rectification is solid state which permits cooler operation and reliable performance. The amp is configured for ultra-linear operation allowing greater power output and minimal use of feedback.


    The amplifier features an extremely stiff power supply; significantly larger than needed for primary filtering. In the early days of tube amps, chokes were easier to come by than caps and more reliable. As such, large chokes were utilized for primary filtering. As capacitor production gained reliability and costs came down, cap filtering and smaller chokes became the norm. In a single-ended design, a regulated and extremely quiet power supply is very important. Using a large 5 Henry choke is expensive, but yields significant improvements in reduction of DC ripple.


    The chosen output transformers are over-spec'd and the highest quality. Ampsandsound considers the output transformer as important as any other design choice. When buying any tube amplifier, the weight of the output transformer can be directly proportional to the quality of sound. In general, larger outputs have more massive cores which are less prone to saturation and have higher inductance.


    Larger cores and greater inductance allow the transformer to carry a low-end signal with minimal distortion. These transformers are bench tested to perform down to 20hz and up to 20khz. Even if your speakers only go to 50hz like a classic LS3/5 two-way, having an amplifier able to drive that low is pivotal in recreating the whole soundstage.


    Choice of Loudspeaker?


    The Bigger Ben pairs well with most speakers 94db and above. However, Bigger Ben is so quiet it will perform beautifully with full-range or horn-loaded speakers of efficiency above 100db, 700 micro volts RMS noise at idle. Speakers that can go down cleanly to 30hz really bring out the very best of the amp. 20z-20khz -1db at full power. The Bigger Ben (depending on choice of output tubes) will output between 5-7 watts, but there's a lot more in the tank than that when matched with appropriate loudspeakers.


    Tubes:

    The amp is compatible with all 6l6 family tubes, including the 6l6GC, KT66, KT77, KT88, KT90, and EL34s. The driver tube is a 6SL7.
