This is my new diy integrated amplifier!
Audiophile Mosfet, Dual symmetrical differential power amplifier
Direct Signal Purist Concept. it uses 2 pairs 2SK1058/J162
per channel produced by Renesas designed specifically for audio
application. Unlike conventional amplifier, it only require 2 stage
signal amplification to drive these mosfets, hence very natural sounding.
You can feel the drum sticks hitting the cymbals and the piano hammer
hitting the strings'
130watts RMS 8ohms
250watts RMS 4ohms
THD : 0.008% (20 Hz : 20 kHz, 8 ohms)
Frequency Response 4 Hz - 100 kHz
Damping Factor (20-20K Hz, 8 ohms) : 500
Signal to Noise Ratio : 120 dB 'A' weighted
Input Impedance/Sensitivity : 33K / 1V
Total dead silent at idle, absolutely no hiss or hum at full ear contact with tweeter and woofer at gain of 40X (32dB)
and an input Sensitivity of 1V for rated output of 130watts RMS 8ohms
Complete silence, No thump or noise during turn on/off . (No relay, Direct output)
Studio Reference has two pairs of balanced input differential..This will ensure accurate imaging of every instrument
and vocals at complex and high energy passages.
Very Low noise selected components throughtout.
