![]() Of the devices mentioned, I should point out the NAD C510 does employ the Zetex (now CSR) DAC chip which is its own particular design. Its when you get audio sources that are 24 bit where you may experience some dynamic truncation as you only have 8 bits remaining before you could potentially impact the digital source when attenuating the signal digital. The majority of them operate in 32 bit depth, which provides a pretty good degree of attenuation before any dynamic truncation would occur when dealing with standard red book. I just wanted to give you a better understanding about volume controls that you may see in various DAC devices. Increased Input Impedance allows our amps to be paired with all preamplifiers - even the most esoteric tube preamps." Red Dragon: " Red Dragon Audio designed the M500MkII with customer feedback at the forefront of the process. The earlier Red Dragon’s had a low 12kohm input, they saw this error for some pre’s and the later MkII Red Dragon it’s said to be much higher (they don’t say how high) to accommodate these pre’s There can be impedance matching problems to an amp if the amp is lower than 33kohm input impedance. TfatsYour going in the right direction for the most transparent/dynamic sound, by looking for a dac that has volume control in it.īut there are two ways this volume control can be done in a dac.ġ: In the "digital domain" which to is best "if" the volume is not reduced too far, so to introduce "bit stripping" (a reduction is resolution), this can happen if the volume is reduced below approx 75%Ģ: A dac with an analogue domain volume control, no "bit stripping" problems with these.
