RE: Intel is taking a risk....

What do I hear comparing a CIS zero crossover diode vs a 1N5408 standard diode. Other posts state the treble is improved. Perhaps my ears are not good enough to hear the difference in the treble, but the bass is definitely improved. The bass is tighter, quicker and sounds more musical vs more of a simple tone with the standard diode.

The Allied 395 (Pioneer SX-1000TW) fortunately had room to install 1/2 length TO-220 heat sinks. I used a bolt on heat sink without an insulator to achieve best heat transfer. A clip on TO-220 can have only 60% of the heat transfer- do not use. If you cannot add a heat sink of 1/2 size for 50 watt per channel or full length TO-220 heat sinks for 100 watt per channel receivers, you have to use the Hexfred. CIS (Cree) diodes have high leakage and it gets worst as the diode heats up.

CIS (Cree) have zero crossover noise and Hexfred have a little crossover noise, but far superior to a standard diode such as 1N5404.

Many receivers have the single diodes close to each other on the circuit board, thus the heat sink fins on one side must be removed to prevent shorting. Even 1/2 of a half size is ok for receivers using a Hexfred up to 50 watts per channel. If heat sink height is available, use a full size TO-220 heat sink with the fins cut off on one side.
