The modification is device specific. I explain that once an example for a Cambridge Audio CD players. This of course is transferable to other devices. modification Cambridge Audio:
As with all high-volume devices can also use the Cambridge CD player, with reasonable effort, be clearly improved. Even the "untreated" devices are, for the price range, good CD player. Anyone who has experienced even know what you all there "tease out" can see the term "good CD-player "with different eyes.
The device is compatible with all tuning options, such as fitted 80VA toroidal transformer, Master Clock and Power Supply. The comparison of the maximum modification of 340C exchanged about 80 components or supplements . Depending on the device type, this can also be more than 120 components
for modification Cambridge Audio Azur 340 CD player series.
The power supply is also the first point: the Cambridge players have indeed a sufficient transformer, but also as the toroidal transformer "more or less" buzzing annoying, and besides a lack of "hard" power switch (640C V2) is always listening. Thus come "sensitive" ears can not help but to replace the built-in transformer by on our behalf of hearing-way-made, molded and shielded toroidal transformer 80VA. These transformers are specially made for the Cambridge CD player, with current best core material and a shielding winding between the primary and secondary side. In addition, all capacitors are swapped to buffer the operating voltages. Thus, from the standard, affordable approximately one 10.000μF 640C V2 through our conversion is the best around 26.000μF, reservoir capacity for faster drive, disk drive controller and processor, DAC and analog output stage. Some of the electrolytic capacitors Films are connected in parallel to even the very last "RF Störschnipsel" shut briefly, and that although the newly appointed FC and FM frequencies are suitable for types already up to 1 MHz. Add to that fast, soft-recovery rectifier diodes, and the case is (cautiously) attenuated. The better and faster current supply is always positive, and the precondition for further steps. On the one hand the drive is in a position to much more information stored on the CD actually read, because the focus servo and regulations, work much better. Second, benefit all circuits in the player of the trouble poorer supply voltages. Only now It makes sense, the analog output filter "musical" to a vote, and to use better Operrationsverstärker that would otherwise make only the weaknesses of the current supply place. These are high quality. Top and bottom metal are inevitably vulnerable to resonance. Here, special materials for immobilization of the housing are used. As a quick power is immensely important to the drive, but on the servo board space for only a "large" capacitor, it is a board on which "blocked" 4 x FC 8.200μF capacitors are additional reservoir capacity. Since the rectifier diodes are available, this board between the ring core transformer and the servo board is looped.
Precision Clock:
Although this point for models 540C and 640C V2 V2 was solved relatively expensive, we recommend that all devices use the master clock, thanks to the two separate, but absolutely synchronous clock outputs can drive the control and the DA converter separately, but in the "same time" supply. The installation is therefore recommended, even when operating as a drive. Without the sound is clearly "tired" with drawn and not so clear.
And after conversion:
After the conversion, you are in effect a new Device: Suddenly you hear details that you have not even imagined before. The musicians can be clearly differentiated from each other, and the reception room is more understandable, although the musicians are without upsampling still more or less on a line between the speakers. But then this "enthusiasm" of the musicians on "making music"! Who has ever experienced, looking at once what has been missing ever! A disadvantage can not be denied: bad shots, or even MP3 files sound, then mercilessly bad, good recordings that may still come from the 60's or 70's benefit, but uncommonly. As one might feel smooth one weeks' leave, and the library from scratch ! Experience
tuning kits for various stereo equipment or professionally remodeled and ready to play hi-fi components with the optimal modification are available from AUDIO IMPULSE and listen paths.
