Empirical Audio was showing their Overdrive SE DAC/Pre ($5,999) that features BNC S/PDIF, Async USB, and I2S inputs (24/192 for all inputs) and RCA and XLR outputs and you can drive an amp directly with its internal volume control. That said, an Arte Forma Pearl preamplifier ($1,800) was in use along with their 805 SE Monoblock Amplifiers ($4,000/pair) driving a pair of Vapor Audio Aurora speakers ($2,995/pair stands included).
B.M.C. was showing their line of components including the BDCD1.1 Belt Drive CD Player/Transport, BMC DAC1 DAC/Preamp ($4,700) and BMC AMP M1 monoblock amplifiers ($7,900/pair) while using the Antipodes Music Server ($2,300 2TB, $2,500 4TB) with a SOtM mBPS-d2s Intelligent Battery Power Supply ($400). The Antipodes Music Server includes a drive for ripping your CDs, comes in black or silver, and offers USB output to your DAC of choice.
Music Culture Technology was showing a complete system from their Elegance Line that consisted of the MC 501A CD/USB Dual Player ($3,995), the MC 701 Integrated Amplifier ($4,595), and RL21 Speakers ($3,495/pair).
Stahl-Tek of Clute, Texas is a company that's new to me and they were showing their new Opus CDT CD Transport ($37,000), and Opus DAC ($35,000). The DAC's inputs include I2S via HDMI, S/PDIF (RCA and BNC), AES/EBU (XLR) and USB and there are single-ended and balanced outputs. The Opus DAC can handle up to 24-bit/192KHz data. Stahl-Tek also offers the Ariaa DAC ($12,900) and the Audiophile Bridge to Computer USB-S/PDIF converter (S3,500).
That stealthy-black (and very difficult to photograph) slab is a prototype of MSBs new Analog DAC ($6,995 + $995 w/optional analog volume control which also adds a pair of analog RCA inputs). My timing was off with the Analog DAC's since every time I went in the room it was sitting silently on display. The inputs of the Analog DAC are modular and you can select from USB2, MSB ProI2S, standard AES/EBU and S/PDIF, RS232 and a MSB Network interface module that allows for firmware upgrades. The case is milled from a solid aluminum plate and next to where you see the illuminated volume level there's a flush-mounted rotary volume control and a push-button input selector. The Analog DAC can handle up to 32-bit/384kHz data as well as single and double rate DSD (64x and 128X DSD).
Also on silent display in the T+A/Dynaudio room was the diminutive T+A Cala multi-source UPnP/DLNA compact stereo receiver ($2,200) and matching CS Mini loudspeakers ($850 per pair). The Cala puts out 55 Watts into 4 Ohms and includes an FM tuner, a streaming client for Internet radio, network access (Ethernet and WLAN), and USB for flash drives and iOS devices plus a Bluetooth module. Supported file formats include MP3, WMA, AAC, FLAC, OGG-Vorbis, LPCM, WAV and the Cala can handle 24/192 music files.
The Dynaudio XEO 3 ($2,300 per pair with transmitter and remote) and floor-standing Xeo 5 ($4,500 per pair with transmitter and remote) are powered wireless speakers that come with the XEO transmitter which includes an optical Toslink digital input, USB input, a stereo mini jack input, and a pair of RCA inputs. So you can connect your computer to the transmitter and send 16/48kHz data to the XEO speaker which keeps everything in the digital domain right up to the speakers output so there's no D/A conversion happening until the loudspeakers output hits air.
The T+A DAC 8 ($2,900) was making its official debut at RMAF 2012. The DAC 8 is a 24-bit/384kHz capable DAC and its inputs include 4 RCA S/PDIF, 1 Toslink, 1 BNC, 1 AES/EBU, 1 Asynchronous USB, and for T+A system owners the "Control Link". Outputs include balanced and single-ended RCAs as well as RCA S/PDIF. The DAC 8 can also act as a preamp as it includes an analog volume control. There's also 4 digital and 2 analog filters so you can shape the sound to your liking and a front-mounted headphone jack. There's also a T+A app for iOS and Android devices.
Sonus Veritas was showing a full stack of their electronics including the Modena Reference Class A Differential DAC ($15,999) that includes 4 inputs (2x S/PDIF, 1x Toslink, and 1x USB) and optionally adds AES/EBU and I2S to its transformer-coupled tube output stage. Also in use was the Sonus Veritas Genoa Preamplifier ($15,999) and KT120 based Class A differential tube monoblock Florence Power Amplifier ($TBD) driving a pair of ProAc Response D40R ($12,000–$14,000/pair).
Bel Canto was hiding their new Asynchronous USB Link Converters the mLink ($375), uLink ($675), and REFLink ($1,495) and I say hiding because they're small, sit near your computer and take your computer's USB output (up to 24/192) and convert it into S/PDIF or LightLink ST Fiber the latter capable of running over 100 meters.
