It's hard to keep up with China's Questyle as their products seem to multiply in-room. In terms of new, I was directed to the ICEpower'd R200i 5GHz Wireless 200W Mono amplifiers ($1500) which put out 200W into 4 ohms and also house a 24/192 and DSD capable DAC.

The matching T2 Wireless Transmitter is where your physical connections are made which include 1x analog RCAs, Toslink, Coax S/PDIF, and USB.

The Questyle Reference System Gold Edition ($12,500) is the company's all out assault on the state of headphone art. The pictured stack includes the CMA800R Current Mode Headphone Amplifier x2, the CAS192D DAC, and the CMA800P Current Mode Preamp.
