Shorting plugs

I had my spare RCA sockets on the preamp shorted and thought that I didn’t need to worry about the XLR and AES/EBU connections.Wrong assumption! Shorting the latter resulted in a significant reduction of hash and increased clarity in the treble as well as more precise positioning in the sound stage. Everything matters and as tweaks go this one is value for money.

I made shorting plugs for the unused inputs of 2 battery powered stereo phono preamps (used as mono's) and the improvement in SQ  was easy to judge/hear.

The parts cost from RadioShack was well less than $1 per unit and the assembly time was approx. 30 seconds per unit after the soldering iron came to temp.
