MADE IN SERBIA
 
This Amplifier is an EXTREMELY Unique build. In fact, Ive never seen anything like this circuit.  Its Single Ended 100% Class A at 100WPC. 100% point to point wired. No Solder, Output transformerless, direct coupled, zero negative feedback, no capacitors in signal path and it uses one single military grade ceramic vacuum tube wired inbetween the 2 electrodes of the single very high duty FET output device.  This is as pure and fine as it gets.  Best with 8 ohm speakers 90dB and above.  ( its fine with 4 Ohm at 86dB but I like to optimize for the highest performance results.)
 
Last amplifiers you'll ever buy territory. ABSOLUTELY SUBLIME sonic reproduction. 
 
Could easily be sold for $40K but I wont do that to you ... 
 
You know who you are for this piece.  Youre a seasoned Audiophile that lives for the unique, highest class, heirloom level audio products. 
These amps are a very high value vs performance, vs uniqueness and purity of circuit. 
 
I give them a 9 out of 10. HIGHLY RECOMMENDED
