Real control center of your Hi-fi system
The new preamplifier PX1 is the point of reference. See for yourself : Designed around two mono preamplifiers built in the same box, our stereo preamplifier PX1 can be qualified as a real dual mono, two EI standard transformers , shielded with mu-metal sheet, expensive but really efficient solution. The PX1 is the focal point of your High fidelity system.
Even if the sound quality was our main priority, we would like that our preamplifier should be able to run all the current sources : analog, dematerialized or physic digital sources Nothing has been forgotten, each input has been enhanced in order to achieve the highest level of music resolution.
The PX1 offers nine analog inputs such as balanced input and one customizable MM or MC phono input with double level. The parameters of the phono cartridge capacitance are adjustable. The digital side was also not forgotten, and the PX1 offers three optical inputs, one coax, one USB B (asynchronous X-mos) as one USB A. The conversion of the digital signal is done by the famous Wolfson WM8740 converter. These digital inputs are completed by a proprietary protocol allowing to connect the direct path Bluetooth adaptor X-FTB01.
It is a direct processing of signal (direct path) in order to keep the original quality of the signal . The interactive menu offers you 2 modes of use. The mode Class A or the mode « discrete. The Class A output is built on a circuit based only on bipolar transistors. It is double cascade circuit offering a highest performance that allows to control and limit the distortion, so very homogeneous and polarized in Class A. The discrete output is a stage based on a more classical typology with a JFET input differential stage and a current mirror with bipolar transistors with a polarized Class AB output. This typology brings more odd harmonics distortion, sometimes less appreciated when you are listening, but sometimes perceived as well defined too.
The use of the PX1 is particularly easy due to its single rotary key with button push to accede to all the menu choice as input selection, volume adjustment, tone settings, loudness, APD function (disconnection of the auto power off after 30 minutes of inactivity) On the outputs side, the PX1 is also really complete as for inputs : one balanced XLR, one unbalanced Cinch, one Rec Out, one Pre Out Hi pass, two sub-bass.
Last but not least, the engineers didn’t forget the headphones listening lovers, so under the device you will find the switches that will allow you to adjust independently gain and output impedance for 2 headphones (gain : +6,0,-4dB, output impedance : from 0 to 100 Ω).
