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.

Coda Technologies S20


The S20 amplifier is a precision device, designed in an effort to provide the listener with unmatched sound quality through superb design and construction.

Precision Bias Class A/AB operation, 200 watts x 2 into 8 Ohms, 400 watts x 2 into 4 Ohms, providing a max output power of 10 watts Class A (into an 8-ohm load) per channel.

In bridged mode, both channels act as one amplifier providing a maximum output power of 800 watts @ 8 Ohms.

1 Ohm load stable

Double-sided gold-plated circuit boards

Frequency Response: -3dB @ DC to 100kHz

Distortion: < 0.04% from 10Hz to 20kHz

Gain: 26dB

Noise: Less than 120dB referenced to rated output

Maximum current: 60 Amperes peak per channel

Input Impedance: 50k Ohms unbalanced/1k Ohms balanced

Output Impedance: 0.04 Ohms from 20Hz to 20kHz

The main power supply of the amplifier consists of a 1500VA toroidal transformer with independent rectifiers to isolate the channels from one another.

80.000 uF of total capacitance provide effective filtering.

The topology and component selection is built on the foundation established by the System 100.

Balanced interconnections are provided to take advantage of their greater noise rejection as in the System 100.

Dimensions: 44.5x15x32 cm (LxHxP)

Weight: 21 kg

Made in USA

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.

High Precision Direct Drive Motor

Electrical Lift

TP124 Tonearm

Removable Headshell (SME connector)
