The Diablo is a high performance, audiophile grade phono amplifier, designed for ultimate transparency and realism. It will maximise the performance of a wide range of phono cartridges from ultra-low output Moving Coils to high output Moving Magnet types.
As with the Dino, the Diablo will accept a wide variety of MM and MC cartridges with adjustments for amplifier gain and cartridge loading on the underside of the unit. Four high speed low noise voltage regulators effectively turn this into a dual mono design in one box.
The prime power supply for this unit is the 'Never Connected' PSU. It is however available with an in-line toroidal supply as a starting option.
The Diablo is user adjustable with a set of four DIP switches on the underside of the unit. These switches allow for adjustment of cartridge loading and a further set of four provides gain setting. The circuitry is signal non-inverting and constructed using high performance, audio grade bipolar and JFET operational amplifiers from Analog Devices and Linear Technology. Metal oxide resistors and ultra low impedance capacitors throughout for lowest possible noise.
The RIAA equalisation network is part passive and part active. The capacitors and resistors used in this stage are very close tolerance audiophile types. Four 'state of the art' ultra low impedance, low noise wide-band voltage regulator circuits are employed to power both channels and are largely responsible for the high sonic performance of the Diablo. The non-ferrous cabinetry is made of aluminium, a design that reduces eddy current propagation that can affect sound reproduction in subtle but deleterious ways.
Two versions of power supply are available for the Diablo, the basic toroidal transformer power supply and the fully blown 'Never Connected' PSU. As you go up from the AC supply to the 'Never Connected' you benefit by a major increase in audio performance. Both power supplies are in separate boxes to keep noise and hum levels as far away as possible from the sensitive audio circuits.
Toroidal AC Power Supply
The Toroidal Power Supply option is provided as standard as a low cost introduction. Performance level will be more than adequate for many users, but you can upgrade at any time to the 'Never Connected' PSU.
The ABS molded housing of the Toroidal power supply contains an in-line low noise 40VA transformer. AC current is fed to the Dino where it is rectified to DC and regulated with two high performance, wide bandwidth Super Regulators.
The Ultimate Power supply for the Diablo - the NCPSU
The NCPSU (Never Connected Power Supply Unit) has completely different electronics to any conventional dc power supply. Instead of an over sized toroidal transformer, there is a PCB mounting variety followed by the revolutionary noise reduction circuitry that is called 'Never Connected'.
Although the regulation circuit is physically connected to the incoming mains, it is disconnected electronically. A monitoring circuit detects the portion of the sine wave that is charging the first of a pair of electrolytic capacitors. Once this first capacitor is fully charged, the diode bridge rectifier turns off and a MOSFET switching circuit transfers the charge from the first cap to the second. This cycle is repeated continuously.
At no point in time is the regulation circuitry electrically connected to the incoming rectified mains - hence the term 'Never Connected'. The overall result is a large and measurable reduction in mains borne noise. This dramatic reduction of mains borne noise enables the Diablo phono circuit to give of its very best.
High Performance Interconnect
For users of the Diablo NCPSU, a futher upgrade is available in the form of a High Performance Interconnect to link the two components.
We endeavour to despatch same day for orders placed up to 12 noon on available stock items (items with stock message "Usually dispatched within 24 hours"). Please remember to check with us first for a physical stock check if next day delivery is important to you. Any items with stock message "Usually dispatched within 72 hours" are items that we do not hold in stock but order in from the importer or manufacturer as soon as a customer order is received. Occasionally these may be delayed beyond 72 hours due to importer/manufacturer stock levels but we will inform you as soon as we can if this is the case.
