WYRED4SOUND STP-SE IN HOUSE UPGRADES

Wyred4Sound recently announced a Stage 1 and Stage 2 upgrade for the STP-SE Preamplifier. Done in house. Stage 1 upgrade cost $950.00. Upgrade consists of rhodium plated Furutech fuse. Discrete regulator's. 24 custom Vishay Z-foil resistor's that are always in the circuit. Stage 2 cost $1950.00 and consists of Furutech IEC inlet, rhodium plated Furutech fuse, 72 cutom Vishay Z-foil resistors throughout the circuit and volume control and upgraded with 16 audio grade capacitors throughout the circuit. Wyred's wholesale cost for each Vishay resistor is $15.00.

I did a few of the Vishay Z foils on my SE when it first came out. Also direct coupled the transformer to the chassis and replaced all the chassis mount fasteners with brass. I replaced the fuse with something else and much better. I spoke to EJ about these mods and he actually gave me the values needed for the resistors. Tom

The Z foils cost me $14.34 each. There is always a resistor at the output for each channel. Volume indicated on the display requires 32 resistors for settings 32 thru 47. My listening range. That incomplete number of resistors and no other parts adds up to $459.88..So yea there could easily be over 1k in parts. The Vishays need to be handled with care because they are naked elements. No coated covered element that would retain resonance. Tom
