T.H.E. Show Newport
Beach 2015 Report
Questyle had their first showing worldwide of their new 150i integrated amplifier that produces 150 wpc in Class current mode design. Less than 5 watts is in pure Class A, with the remainder being Class AB. They kept the design simple to ensure sound quality, with 6 inputs, (2 balanced XLR, 4 unbalanced RCA). There is a preamplifier output, which is unbalanced RCA. The speaker binding posts are custom made out of pure silver. At 100 watts the distortion in 0.0003, with negative feedback to keep the signal stable. They say their feedback loop is extremely fast to avoid the problems of other designs. Pricing is expected to be around $6000.
Questyle QP1R portable player housing is made with machined aluminum, with the front screen being Gorilla glass. Anyone who has used an iPod with wheel will feel right at home suing this unit. Of note it that it is made at Foxconn, the same place Apple devices are made. So we need to thank Apple for making their product in China, as it greatly helps their technology and export economy. Questyle's QP1R can handle DSD64, DSD128 and 24-bit/192kHz audio files including ALAC, APE, FLAC, AIFF and WAV. Internal amplification is via pure Class A, all discrete transistor / component that incorporates Questyle Audio's patented Current Mode Amplification. A three clock integrated circuit with FIFO asynchronous architecture and three voltage-stabilized power stages ensure accurate sound. With CS4398 chips, the DAP can playback a variety of music with excellence accuracy.
The QP1R has a very clean, fast sound and could easily drive the Noble Kaiser 10 CIEMs. i used my 64GB memory card and it loaded up all the songs blindingly fast and efficiently. The GUI is extremely intuitive and easy to use. Am very much looking forward to a production unit for review when it comes out.
