rick_n : THANK YOU!
audphile : I would ask the guys at Teddy Pardo to make me a power supply and implement it.
External Power Supply For My Audiolab 6000CDT CD Transport
I have an Audiolab 6000CDT cd transport. I'm wondering if an external power supply would boost its performance.
I purchased and installed a Teddy Pardo power supply for my Bluesound Node and got a huge leap in performance. I'm wondering if a power supply mod for my Audiolab cd transport would boost the performance there.
I'm running an Audio Research Reference DAC along with the Audiolab 6000CDT cd transport.
How do bigger external power supplies improve source components?

interesting. Ok. Considering the 6000CDT already has linear power supply and Teddy Pardo are mostly for units that utilize SMPS, not sure how that’s going to work. It would probably have to be an upgrade to the caps and transformer inside the 6000CDT. Which could be a worthwhile investment if you plan to keep the unit and not sell it - you will never recoup your investment with a modded component. |
I wouldn't pay too much attention to architecture of power supply. There are extremely quiet resonant mode SMPS that switch at zero voltage / zero current, while Linear Power Supplies are in reality primitive switchers that operate at 120Hz producing a lot of high frequency noise (switching at max voltage) and the only "Linear" part of it is that they are line and load unregulated (at least in power amps). Benchmark reduced noise by 10dB by switching from linear power supply in DAC1 to SMPS in DAC2 and DAC3. SMPS got Really bad rap from noisy computer applications, but can be wonderful if done right. My Benchmark AHB2 has SMPS and is very quiet. All current Rowland products contain SMPS (even preamps). Why then well designed SMPS are not that popular? Perhaps because of demand - people believe it has to be heavy to deliver a lot of power while "switching" has to be noisy. After all class D is controlled SMPS. If it is quiet enough for an amp it should be good enough just for power supply. |
@kijanki good points. I have Chord Hugo TT2 that uses SMPS and sounds fine. It’s all in the quality of the SMPS and implementation. However, I do prefer a good quality and properly implemented linear power supply as in my experience the transients and dynamics are typically better with components utilizing linear supply with good filtering. In case of Audiolab, I wouldn’t screw around with the power supply there. But I would deaden the case - there are plenty of real estate there to apply some noise and vibration isolating Dynamat.
