"DHARMA" 2A3 MESH
Origins of the name
Dharma is a Sanskrit word which has many meanings among the religious communities of Western Asia. It can be translated as ‘Duty’, ‘Law’, ‘Cosmic Law’, ‘Natural Law’ or even ‘the way things are’. Ultimately the word Dharma represents what is consistent with the order of the universe, therefore truth and justice.
The monophonic integrated speakers, ‘DHARMA’, perfectly follow the natural path of sound. The choice of making them IMA allows to concentrate the resources where they are needed. The choice of monophonic units allows the complete separation of the PSUs with all the advantages that follow. The only stage of gain/driver compared to the 2A3 eliminates redundant and expensive line preamplifiers. As we’ve said before, we consider the preamp to be a useless and costly element below 8 Watts.
If everything is designed by the book (speakers of at least 94dB/w/m) then the results are astonishing.
Specifically, DHARMA benefits from single ended and fixed bias circuits. Obviously with no feedback whatsoever. The coupling between driver and power amp is carried out via custom Clinamen transformer with an extra-large ‘C’ nucleus, with extra fine lamination for the best dynamics and timbre neutrality. Of course the cabling is exposed end-to-end.
The driver tube is a pentode connected to a triode that we adore, the D3A; it is not the typical ECC81-82-82 (sadly 90% of the tubes used in the Hi end sector).
This ‘triode’ has a very high trans-conductance and if it is used properly it can achieve the vivid and dynamic sound characteristic of Clinamen’s music. The high trans-conductance gives gain and strength in driving the grid of the power amp. The downside is a drastic selection of the tubes in order to find a pair with the same technical features, but since Clinamen makes handcrafted products, this is not a problem.
The D3A benefits from a power supply tension stabilized ‘naturally’ thanks to the gas charged regulator oD3.

The final tube is a 2A3 Emission Labs in MESH edition. Emission Labs is the only current tube producer with a true MESH plate. The Chinese tubes that claim to be MESH are in actual fact solid pierced plates. In the EML the plate is in true metallic mesh like in vintage tubes. What happens to the sound with mesh tubes is quite simple; it is a unique scenic reconstruction engineered to perfection in every detail, very high micro dynamic thanks to the absence of resonance of the plate. The low range is sleek and with no reverberation.

The anodic power supply of the DHARMAs if only made of polypropylene condensers: NO ELECTROLYTICS! This expensive and bulky choice is a foundation for us; the timbre neutrality and the speed in current supply of a unit to the plastic film are much bigger than an electrolytic capacitor. Furthermore the latter have a limited life span and their performance deteriorates with age.
Those who have listened to a Clinamen chain know the feeling of speed and lack of reverberations and resonances that can only be enjoyed with live music.
The DHARMA frames are woodwork masterpieces. The frames are made from 28mm thick solid Zebrano wood; the panel’s lining and the upper frame are made from 2.5mm carbon fiber. The Clinamen logo is carved with a pantograph and filled with black stucco.
Another gem of the DHARMA model is its lower plates made of real Italian slate, made with a water jet cutter and a G-clef frieze. This unique solution gives an extremely solid base to the amplifiers and ample muffling of vibrations. The spring feet are optional but are advisable.

The resting current of the final triodes is constantly monitored by the elegant instruments at the front with a blue backlight. The instrument indicates mVolts, but thanks to its calibration, the mV read corresponds to the mA of anodic current flowing between the cathode and the mesh plate. We have not used a milliameter purely for reasons of sound cleanliness; the milliameter, with its mobile reel, works in series with the signal. This is not the case of the millivoltmeter which works in parallel; thanks to its infinite input impedance it does not affect the signal. As you can see, nothing is left to chance.

On the back of the amplifiers we find the inputs for the two channels, output terminals for all speakers from 6 to 10 ohm and the socket for the domestic power supply with integrated fuse holder (500mA rit). Finally we have a switch to select the tension between 220 and 230 volt.
