Note: Submenus under some titles
Here are the products featured from my good Italian friend, Stefano Buttafoco.
More details on his new website:
An electronics engineer by profession, his ALDEBARAN monoblock phone pre-amp is a no compromise original design.
He has also turned his expertise on the Denon DL-103. His modification transforms this modest MC into a high-end perfomance product, & it compliments Terminator perfectly!
Latest addition is his Stereo to Mono summing device.
See details below:

The modification that CLINAMENAUDIO carries out on the DL103 is a mechanical improvement. All the electrical specifications remain the same.
The only positive function the case performs is protection of the internal components! Other than that, its effect is detrimental to the sound. The volume of air trapped within the case acts as an acoustic chamber: the air is excited by the movement of the stylus causing internal resonance which adds distortion to the audio signal generated from the moving coil of the cartridge.
We remove the plastic cover & replace it with a CNC high-density isostatic graphite shell which converts any resonance into heat, dissipating them in an acoustically harmless way. The sound of the cartridge is totally transformed by this modification!
We are also working on an ebony version.

Stereo to Mono Summing Device

This device combines the Right & Left stereo channels in a single mono channel without losing any information; a necessity for enthusiasts that enjoy listening in Monoaural mode.
Most summing devices are made using resistive techniques which causes a loss in dynamic response.
The CLINAMENDAUDIO device uses a Superpermalloy Transformer to sum the two channels into one. This method maintains the correct balance without losing any of the dynamics!
