Description for Stradivari 211 Power Amp: New Audio Frontiers offers to all music lovers who are looking for a valve with a linear sound over the entire audio range with a detailed tonal and dynamic 211 STRADIVARI. We offer this product for all those who wants to benefit of all the characteristics of refinement, warmness and precision that directly heating triode in single ended configuration can provide. This integrated amplifier running in pure Class A, with its 20 Watts for each channel delivered by an 211 driven by an ultralinear SRPP, can drive without any problem, in a domestic context, most of the loudspeakers on the market with an efficiency of at least 90dB. The output transformers are of the highest level, handwound using silver plated copper litz wire. They are built with core in M0 (the M0 is the thick of core in 0,1mm) and the winding is double wire for avoid the parassistic oscillation and many loss into the core. Output Tube bias is automatic and doesn’t need any regulation, with cathodic resistors bypassed by high quality capacitor. The rectifier for anodic power supply is made up by two 5R4GY directly heated rectifier tube. All these things give the amplifier an incomparable sonic quality that satisfies the most demanding audiophiles. The amplifier is made with strictly selected components in order to achieve the best sonic fidelity and the greatest reliability. This integrated amplifier completely disappear on listening and offers a wide threedimensional soundstage which is a rare example of musical breath and holographic sound. Specifications: Model: 211 STRADIVARI Type: Power Amplifier Continuous Power: 2 x 20 Watt on 8 Ohm / THD 5% Sensitivity / Input Impedance: 700 mv / 33 KΩ Power Consumption: 350 Watt max Dimensions (W x H x D): 35 x 24 x 56 cm Weight: 50 kg Description for Stradivari Line Preamplifier: New Audio Frontiers Italy opens with this realization a new product line: the Stradivari Line and the Stradivari Phono. We have added some substantial changes to the new pre-line that has become the Stradivari Line Evolution. The main changes have been made to the power circuit and in this case a new pair of separate transformers: one dedicated to the anodic current and the other one for the filaments of the valves. The current is completely rectified with valves with a 5Y3, while on the line signal all the capacitors have been replaced with the most performing Mundorf. It is a Line Preamplifier that has been designed to meet the demands of the mostexacting audiophiles; the study of original circuitry and the choice of components of the highest quality make it a point of reference between devices of the category. Meticolous care has been placed in the circuit of high voltage power supply that usesa very high gain error correcting stage based on the use of a pair of 12AX7 whichdrives a 6CA7/EL34 as power tube. The design of this circuit has been optimized to elimi- nate any parasitic oscillations and maintain a costant anode voltage and a ripple less than 250 μV. The excellent filtering and the use of circuit voltage regulators provide the DC voltages to the heaters of the left and right channels of the preamplifier. The heart of the apparatus is, however, the amplification stage itself, which uses (foreach channel) a first tube 5814 / 5963 / 12AU7 / ECC82 as amplifier followed by a 5687 as output buffer. The originality of the solutions adopted mean that you are before a device that combines the qualities of a sound smooth and enfolding, with the quickness of a very wide dynamic that gives an exceptional sound detail. The fidelity of reproduction is a fur
