NICELY ENGINEERED MACHINE, FET FRONT END
WORKS AND SOUNDS GREAT!  *SOLD*
Recently serviced, clean in and out,
all controls are noise-free, all bias adjustments done,
new lamps done.
If you are an audiophile and are after tonal quality, then SX-434 is better than something like SX-680, and certainly much better than any new home theater receiver, regardless of price.
It was designed just like a tube amplifier, with transistors being put in place of tubes.
Best used with smaller bookshelf speakers, SX-434 also makes for a wonderful headphones amp, when paired with something crisp and clear sounding like Sennheiser HD 600.
Equally, it’s perfect for a desktop computer system, to add a measure of sweetness to smooth digital harshness.
Do not underestimate its power, those old school Watts go a long, long way.
