External Power Supply For My Audiolab 6000CDT CD Transport
@invalid Let me offer this - all power supplies are SMPS (they switch and the power is delivered in narrow current spikes with width dependent on the load). Some operate at 120Hz others at 100kHz and the best (like Rowland) at 1MHz. In linear sup... 
Your last concert was to see who and when?
Joe Bonamassa, Aug 4  Red Rock Amphitheatre Colorado.  Fantastic performance and the venue.  
Why can I feel vibration when I touch my network switch or streamer?
Magnetostriction  
Six DAC Comparison
@yyzsantabarbara   Thank you for suggestion - especially important to me, since you know AHB2 and HPS-938  
Chord Hugo TT2 - My experience so far
@audphile1   I agree - it is only recommendation (it works for me).  As for USB, they likely stressed out the fact that in async USB there is no possibility of jitter (since clocks are asynchronous) - ignoring possible indirect source - an electri...

Chord Hugo TT2 - My experience so far
It might not always work, but logically most of the signal gain should be obtained in quiet environment (preamp or DAC) and not in the power amp (heavy currents, more noise) - that's at least what Benchmark recommends for my DAC3+AHB2 combo.  
Six DAC Comparison
@yyzsantabarbara   My modest Hyperion HPS-938 speakers (that I believe you're familiar with) work great with DAC3HGC+AHB2,  Sometimes warmer sound (2nd or even euphonic 3rd harmonic) helps to cover "hot" tweeter or distortion in the system at the ... 
External Power Supply For My Audiolab 6000CDT CD Transport
@audphile1   I believe there are fantastic power supplies in either technology, but SMPS are way more complex to design (and perhaps harder to repair).  Rowland's SMPS operate at extremely high switching frequency (incredible 1MHz) that is much ea... 
External Power Supply For My Audiolab 6000CDT CD Transport
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 produ... 
Bi-amping my KEF R3 Meta speakers.
Sensitivity of both amps is likely different - you need to adjust signal levels.    
Shocked. Need Opinions. How muck power do I need?
Required output current at min load can be calculated. My Benchmark AHB2 delivers continuous 100W at 8ohm requiring 3.5A current.  Let's assume even 5A to give it 100% overhead (200W).  Current will be 4x higher driving 2ohm load (8/2=4) to keep t... 
Shocked. Need Opinions. How muck power do I need?
For every decibel volume increase above 86db requires double the power. For every meter distance requires double the power. Double the power will increase volume by 3dB (+23% perceived loudness) Volume drops at double distance by 6dB. To keep... 
Shocked. Need Opinions. How muck power do I need?
With 40W it will be -2.7dB.  Perceived loudness will be 16.6% lower (still over 100dB)  
Importance of clocking
@greg_f   I forgot that it is specific Audio USB and Firewire.  AES seems to be the best choice.
