![]() The CDA 825 recovers an awful lot of information from CD. A louder sound invariably grabs a listener’s attention more during a comparative demo. While a highish output is not a problem in itself it does mean you have to be careful to match levels when comparing the CDA 825 to rivals. Through the single-ended analogue sockets it delivers 2.4 volts rather than the more usual 2.0 volts, and this doubles to 4.8 volts with a balanced connection, as opposed to the industry standard of 4.0 volts. One thing to take note of is that Copland’s signal output is on the high side. Start listening and it’s obvious all of Copland’s work has paid off. As always with good high-end kit there has been plenty of work put into the power supply design, analogue circuit layouts and choosing just the right components to acheive the best sound quality. ![]() The number-crunching devices used are well-regarded Wolfsan WM8741 24bit/192kHz chips. That should mean a better-resolved sound. This lowers unwanted noise, so improving the signal-to-noise ratio. That feels a little odd at first, but we got used to it.Ĭopland has followed the tried and trusted high-end route of using two DACs per channel. The use of this buffer adds a two-second delay into the signal path, so if you press ‘Stop’ while a piece of music is playing then it plays on just a little longer before it actually stops. Putting this signal into a buffer and then accurately clocking it out again lowers the jitter levels significantly, which means the digital-to-analogue conversion circuitry has a better-quality signal to work from.) (The information that leaves the transport invariably has a certain level of jitter in it. ![]() Once the transport reads the data from the CD it is, rather unusually for an integrated player, fed into a buffer. ![]() It’s designed for top-loading operation and works with speed and quietness. ![]()
