Is PS Audio's Paul McGowan out to harness all of the world's AC for musical ends? You'd think so from the host of new power products in his line-up.

Between 150 and 200 producers of cables and components rely on WBT for their terminations and connectors. Hence, any advance in their line has profound implications for audiophiles. This year, WBT was touting its Nextgen terminations. Composed of either pure copper or fine silver, Nextgen connectors s boast less mass than other WBT terminations, and are claimed to yield superior sound.

Innovation comes from surprising places. Esoteric has always focused on pushing the state of the art with their flagship and pricey digital players (the financially squeemish can skip to another post now), but they've also begun to accommodate digital media wherever it may be found.

Esoteric has upgraded the wiring and parts inside the flagship P-01 and D-01 SACD/CD transport and DAC and has renamed them the P01-VU and D01-VU respectively. Each DAC is a single channel and retails for $16k and the transport will run you $32k. These are superbly built and incredible sounding digital products. Even if you can't afford them, just be glad they exist in our world.

One channel of DAC nirvana.

As more audiophiles start to view their computer systems as another audio source component, finding good sounding ways to bridge from the computer to the preamp becomes paramount.

The touchscreen music server market has picked up a new face with the official release of Blue Smoke's "The Black Box". Demonstrated in prototype form at last year's CES, the final version is a sleek, um, black box with a single disc slot on the front and an array of connectors on the back. Retail is $6995 and should be hitting dealer shelves Q1 2009.

Here's a view of the by now familiar grid of albums on the Elo touchpanel connected to The Black Box.
