Network Switches

QSA Modified Gold Version Audiophile Network Switch - $5,400

"QSA has performed another sonic miracle with their Gold 2.5 G network switch. If you've experienced The QSA Fuses, or AC adapters, The sonic effect of the switch is similar to the Silver and Gold level QSA products in terms of performance.

The Gold version has been treated with their proprietary processes, and materials. It appears to have more crystals used in treatment. The QSA Gold Switch adds one more process QSA calls DSRT (Digital Sound Removal Technology). The claim is removal of the unnatural sound that digital audio can so often impose on music when compared to analog sources."

Can't help being skeptical - it looks like any other switch, except it has glass beads glued to it and costs over half what I paid for my dac - just sayin'

Oh, and the marketing verbiage says exactly nothing - "sonic miracle" indeed!

Melco has up their game on the entry level switch by adding a robust power supply and new chassis,

@jnorris2005 - I agree with you...my only concession to the other side of this question that IF there is inadequate filtering in the streamer or receiver or whatever is connected to the home network, then noise carried on the Cat 5 or 6 cable or picked up from the environment by that cable...then that noise gets introduced into the end piece of equipment. In that scenario there is then a defect in the equipment that needs to be fixed. Surely the engineer that designed this equipment took noise transmission and filtering into account as part of the design. No additional isolation should be necessary. IF it is necessary then the equipment being affected is either defective or poorly designed and should be replaced.

interesting comparison of Network Acoustics tempus switch and the telegartner + optical bridge.
