 Back to our slogan “Best Parts for Better Sound” certainly applies to discrete regulators as well. The Q-power line of discrete regulators demonstrates this all to well. Essentially it is the same circuit but uses Black Gate capacitors for all storage and de-coupling. We have compared the two and certainly felt the Q-power is several steps beyond the super-regulator giving you what the Black Gate are famous for: air, blacker background, increased musicality, far greater resolution, etc… What can we say it’s just better!

Even in the best Hi-Fi, noise generated by regulation masks essential parameters that prevent us hearing our recorded music collections as the performer intended. Compromises made with standard voltage regulation corrupts the circuitry with poor noise levels and slow speed veiling subtle detail, hindering the attack and decay of instruments, detail and space.
A typical electronic regulator has an output noise of approx 40mV within a 1KHz bandwidth, and this noise level increases with frequency. The output impedance increases with frequency from1 KHz up. The slow speed is a product of the regulators narrow bandwidth, and an accuracy of approx 4% is likely to result in voltage drift.
These poor quality regulators are typically; JRC7805, BA05T, LM340T5, LM7805, LM340T12, LM340T15, LM320T5, LM320T12, LM320T15.
Other voltage regulators we have tested which give better results are; L78S05CV, LM323T, LT323AT, LT1084-CT5.
None of these standard voltage regulators provide the criterion for fast transient response, low noise and wide bandwidth, and as a result will compromise the performance of your Hi-Fi.
We have developed a completely different approach and designed a circuit which vastly outperforms standard voltage regulators.
This design starts with a low noise precision voltage reference, the output from this is RC filtered before feeding into one of the industries lowest noise operational amplifiers. The output from this op-amp controls a high current series pass transistor. Incorporated within the feedback loop there is additional filtering. The supply to the op-amp has extra pole of low pass filtering.
A noise level of less than 1mV, and a speed greater than 10x the best regulators on the market enables the circuitry in your CD player to function closer to its potential. Previously concealed low level information is revealed, along with dynamics and detail. A clean, open sound stage is created, with superb definition of vocals and instruments. | Description | Size (l x w x h) | Max Current | Min Input Voltage | Max Input Voltage |
