CES 2013

When listening to audio systems in hotel rooms at shows, all bets are off. But once in a while you get a wonderful sound in the confines of the spot where the bed would normally sit.

Such was the case with the dCS room in the Venetian. The company is celebrating their 25th anniversary and Sony offered an assist in the form of a couple dozen DSD tracks straight from the vaults to hard drive. The Debussy DAC can now process DSD 64 via USB (free software upgrade available from the dealer next week), and for my demo I picked Santana's "Black Magic Woman", settling into audio ecstasy.

dCS also had their complete Vivaldi stack set up at the Mirage hotel, with a presentation hosted by Wilson's Peter McGrath. Once again the sound was extraordinary as McGrath played some 24/88 files of Mahler's Fifth that he had recorded himself with Grado microphones. I only wish every one of you could have been there.

The VEGA is another DAC employing a femto clock for extremely low jitter and retails for $3,500 (a low price point for the femto feature) . It handles PCM streams up to 32/384 as well as DSD, DXD and 2xDSD. The VEGA can also function as a digital preamp and includes a remote that can control the output level. Inputs include AES/EBU, 2xSPDIF, Toslink and "ActiveUSB". Analog outputs are both balanced and unbalanced and the front panel sports a very easy to read display.

It's a simple idea really. Make it easy for anyone at your home to pull out an iDevice and play what's on it over your audio system without having to fiddle with cables and the proper connectors and then a compatible USB port. Some products, such as the Musical Fidelity M1SDAC have this already built in, but if you don't have it, here's an easy way to add it.

The $249 rBlink gives you the ability to connect any Bluetooth device like an iPhone wirelessly to the system. Plug the rBlink into an extra input on your stereo, and then have the Bluetooth enabled iDevice add it from their menu. Maybe not the best sound in the world (though better than it used to be with Bluetooth), but easy for your pals and great fun at parties.

Krell is jumping into the streaming world with a somewhat reasonably priced product that can come two ways: streamer with digital out only at $2,500 or with built-in DAC for $3,500. The Connect has WiFi and ethernet UPnP/DLNA compatibility for NAS drives in addition to internet radio and USB input. The Connect will handle FLAC, WAV and MP3 files up to 24/192. The DAC option adds five digital inputs along with its ESS Sabre 32 bit DAC processor.

Though I was exhausted from a long day of walking through enormous casinos and down seemingly endless halls, I couldn’t resist the allure of flashing lights and loud dance music. I walked into the room and was startled by red-and-white-striped jump ropes spinning dizzying patterns to the music.

“This guy will make your iPod of iPhone look like a toy,” said HiFiMan’s founder and head designer, Fang Bian.

English manufacturer Chord Electronics is known for its sophisticated CD players, which use sophisticated DACs. Indeed there was a huge picture denoting Chord's latest-generation DAC, the QBD 76, at the center of the back wall. As my beat was amplifiers, Chord's designer, John Franks (pictured above), spent the next 30 minutes walking me through the design of Chord's latest amplifier, the SPM 1200 Mk.II ($14,000), a solid-state, 350Wpc stereo mode. The amplifier sits at the bottom of the short stack of audio equipment John is leaning on. He explained that the amplifier has a high-frequency, 2kW, switch-mode power supply, and uses an output stage based on dual-die, lateral-structure MOSFETs with a soft turn/on-turn/off characteristic. This allowed John to use a sliding class-AB design.
