Purity Audio Design Master Reference Linestage

 The multi award winning Reference linestage continues to get better.  We have now paired our amazing DHT (300B or 2A3) input stage with the award winning Reference linestage. 

The Purity Master Reference is a Class A linestage fitted with a DHT front end based on our unique Harmonia DHT input circuit and is the result of years of intensive research directed at attaining the most accurate reproduction of recorded music.  Unique topology and application of the most advanced technological resources and processes bring the Purity Master Reference to a threshold of excellence in sound reproduction.  To add to the main features, the Master Reference now contains 4 completely isolated power supplies. We are using a dedicated power supply for each of the two tube stages as well as for the filaments and remote system. The output stage power supply utilizes a choke input design based around the 274B rectifier.

The balanced version of the Master Reference utilizes transformer coupling at both the input and output. Transformer coupling output results in a low output impedance making the Purity Reference a versatile unit that is capable of driving both solid state and vacuum tube amplifiers with input impedances as low as 600 ohms. Extraordinary transparency of perceived sound which in turn assures the recreation of a three dimensional soundstage.

The Master Reference now incorporates the ultra clean SonicCap capacitors in both the DHT input stage as well as the 6SN7 output stage. Tube filament power is now supplied by a high quality, highly regulated DC supply for the quietest possible presentation.

The Master Reference features a very short clean signal path and uses LDR technology for the attenuation.

Topology

We have taken our Harmonia DHT tube stage and utilized it as the input stage for the Master Reference. Input signal is fed directly into the grids of the DHT tubes. The output of this stage is then fed to the Bent Audio volume control system using the resistor//relay based volume control modules. The volume control then routes the signal to our Reference 6SN7 circuit. 

Balanced Version

1 set of balanced inputs, 2 sets of unbalanced inputs and 1 set Bluetooth input. One set balanced outputs and 2 sets single ended output. When an unbalanced input is selected, the signal still passes through the input transformer maintaining a low output impedance as well as the resolution and transparency transformer coupling is known for.  Single ended outputs also benefit from transformer coupling.

Channel D Lino C 2.2

 

New improvements in 2020 production (Q2 and later, designated Lino C 2.2)

Each active device handling the audio signal chain now has its own additional local, ultra low ESR, low inductance bulk storage located less than 2 millimeters away from each device. This improves dynamics and channel separation (which already were excellent) and slightly reduces harmonic distortion. All other active devices supporting other circuit functions (signal level detection, active input stage class A biasing) each have additional ultra low ESR, low inductance bypass.

Why wasn’t this done previously? Selecting high performance components for power supply bypassing matters a lot, and during initial production of the Lino C 2.0 we were still in the process of evaluating dozens of different new MLC capacitors from different manufacturers, selecting for low ESR, inductance and DC bias sensitivity and eventually found some that were substantially better than others, that is, better enough to make a difference. These are all new components that only became available relatively recently. It wouldn’t have been worth it to blindly incorporate such parts without actual testing: spec sheets don’t provide the kind of information needed. Picking parts without careful testing might not have made any difference in the performance of the Lino C. In the process of this testing we found new parts that were absolutely perfect for the Lino C, and updated the PCB layout accordingly to accommodate them.

There is now full isolation of the signal return path for the unbalanced outputs from the rest of the PCB directly to the driver circuitry, and greater isolation of pin 1 for the balanced outputs. There are additional circuit protection devices on all outputs, and better isolation of all inputs and outputs from EMI and RF. The galvanic isolation of the power regulation board is improved, as is the battery management.

Due to improvements to the main circuit board, the impedance of the passive part of the RIAA network has been reduced by over a factor of 3 compared to the original 2.0 version. Lower impedance reduces the effect of capacitor dissipation which in terms of sound quality improves clarity and definition, while also slightly improving SNR. The lower impedance also allowed upgrading the active RIAA amplifier to a lower noise and lower distortion design. The revised 4-layer PCB improves loop current management, improving channel separation and reducing distortion. The RIAA accuracy is improved. Finally the RIAA board now has its own class A auto-bias circuit, since we found that was beneficial on the main circuit board, as well.

Rike Audio Natalija III Phono Stage

Natalija III has been significantly improved on numerous points compared to the predecessor, which was equally highly praised by end customers, trade and trade press:

-Completely revised circuit design

-New board layout with enlarged mass surface and optimized mass guidance for exemplary calm in the sound image

-Newly developed and optimized Rike Audio electrolytic capacitors for higher efficiency and extremely fast signal processing

-Novel inner wiring made of innovative material mix (silk, cotton, paper) for highest signal purity

-Completely new, extremely solid aluminum housing with 2,5 mm thick front and back and elaborate internal struts to minimize parasitic resonances

-Even higher quality Lundahl transmitters specially made for Rike Audio (MC version)

-Specially made for Rike Audio, extremely high-quality and sound neutral DIP switch for even more extensive adjustment options plus extra base for resistance value and type as desired (MC version)

-Intensive cleaning and sealing of sound-relevant components like RCA, tube pins and tube base with Audiotop Connect workstation to minimize corrosion and transition resistance and maintain maximum signal integrity

As before, the Natalija circuit is based on two Type 6 HM5 (EC900) tubes per stereo channel. This widespread and therefore inexpensive RF triode is great for sophisticated audio applications. Why is she still extremely rarely found in hi-fi devices? Because their implementation requires an exceptional level of circuit work and know-how. On top of that, we have managed to transform the already very solid 6 HM5 in principle into a real long life tube that will give its owner many thousand hours of uncloudy listening pleasure.

Natalija III is available in three versions, as a pure MM level and in MM / MC version with extensive adaptation options to optimally operate virtually any moving magnetic and moving coil pickup. We have developed Natalija 3 Signature for the highest quality standards.

Thorens TD 124 DD

 

The original TD 124 was introduced in 1957 and has been used for decades in countless broadcast studios around the world. Ambitious music lovers also quickly discovered the highly precise turntable for themselves; a dedicated fan base has remained loyal to the TD 124 to this day.

Thorens is now building on this tradition with the completely newly developed TD 124 DD and continues it with innovative technologies. The purist design and basic construction are based on the original, but the height-adjustable aluminium chassis now rests on vibration-damping rubber elements. Instead of the original drive with friction wheel and belt, the new TD 124 DD uses a "High Precision" Direct Drive. This provides powerful torque, allows precise speed control, and keeps unwanted vibrations from the drive away from the platter.

Also new is the tonearm TP 124. It can be precisely adjusted in all parameters to the cartridge of choice and features an innovative anti-skating solution with a ruby bearing and a patented electric tonearm lift to facilitate gentle placement and removal of the stylus.

In addition to the extensive adjustment options, the enclosed headshell provides a great deal of flexibility when it comes to selecting a cartridge. The TD 124 DD also comes with an additional, slightly heavier counterweight that matches the Thorens SPU TD 124 pickup, which is available separately. This is an updated version of another legendary piece of vinyl equipment, the famous Ortofon SPU. Thorens has created the SPU 124 together with Ortofon for the discerning vinyl enthusiast looking for the extraordinary.

Thorens has payed attention to every detail when developing the new TD 124 DD to ensure that it meets the highest aspirations in sound performance. A high-quality external power supply unit ensures interference-free power delivery. In addition to the unbalanced outputs, balanced XLR connectors are also provided, which guarantee optimal signal transmission and thus the best possible sound when connecting the TD 124 DD to a high-end system with an appropriately equipped phono preamplifier.
