Second Price Reduction: From $199 to $165.
Price Reduction!! From $225 to $199. This is highly regarded as a great DAC with 24/192 capability via Toslink.
I purchased this new for $475.00 and have used it on my desktop. I recently bought a CEntrance Dacmini and would like to sell the Carat-Topaz. It sounds great. I have used it both with the usb input and the optical. In my system they both sound about the same, however for hi-rez music you need to use the optical input. I have a few hi-rez files and they sound noticably better on the Carat-Topaz.
It comes with it's original power supply.
I pay the shipping and the Paypal fees.
Korean firm StyleAudio have announced their latest headphone amplifier and DAC, the StyleAudio Carat-Topaz. Bizarre name aside, the packs not only USB but optical inputs, together with a high-end Burr-Brown 127dB DAC, all in an anti-vibration chassis with copper spikes.
Compatible with Windows and Mac systems, the Carat-Topaz DAC boasts 24-Bit 192kHz sampling, a 0.0004-percent signal to noise ratio and capacitors, resistors and oscillators sourced from so many different countries that the end result is better traveled than I am. According to StyleAudio, many of their high-end features from more expensive ranges have been filtered down into the Carat-Topaz.
The headphone driver portion of the Topaz is quite special, utilizing two of the high performance TI/Burr Brown OPA2134 OPAMP's, allowing the Topaz to comfortably drive any headphone from 32ohm to 300ohm. The line ouput section gets the same attention to detail as the rest of the unit and employs two of the Analog Device AD817 OPAMP's, allowing the Topaz to be at home in a high end two channel audio system. Impressively, the Topaz also use four of the TI NE5534 OPAMP's for the I/V section, a testament to their dedication to quality and good sound.
The impressive engineering pedigree and use of top notch parts continues into the DAC section. Utilizing the TI PCM1792 24bit/192Khz DA converter, this DAC is capable of an astounding dynamic range of 123dB with a negligible THD+N of 0.0005%. The USB input is controlled by the proven TI PCM2707 USB controller, allowing use of up to 48Khz files via USB. And, finally, the digital controller is the Crystal CS8416 with low jitter clock recovery.
The Topaz is truly "plug and play" with any Mac OS of 9.0 or later and any Windows OS of 2000, or later
Important: The question from Robart was meant for a different item. The price for this item remains at $225. Sorry for the confusion.
