Class "D" amp? I do not have a clue. Do you?
Mike - Problem with switching power supplies is that most of them are designed to save money and space and not to improve performance. REF1000 for instance in improved version REF1000m has additional power supply with a lot of capacitors on separa... 
Which purchase tipped you into nirvana.
Hyperion HPS-938 speakers. Open, vivid but natural and relaxed/musical sound (with class D amp) - just opposite to Hi-Fiish sounding speakers. Incredible midrange. Uses speakers without suspension (spiderweb). Midrange 6 1/2" is damped with ferrof... 
Is Acoustic Zen better than Harmonic Tech?
"As AZ Absolute is all silver, does it not sound a bit lean in bass?" AZ Absolute IC is 1% copper while AZ Silver Reference IC is 3% copper. Bass with Absolute ICs is strong and well controlled/defined - at least with my gear. 
Class "D" amp? I do not have a clue. Do you?
"With medium efficiency speakers the MEASURED peak voltage is above 100v." - I don't understand it. What speaker efficiency has to do with the voltage. Icepower 1000ASP voltage is regulated always 80V and since it is bidirectional it becomes +/-80... 
Class "D" amp? I do not have a clue. Do you?
Pugstub - It might be related to fact that Icepower's full bridge places half of supply voltage (30-40V) on both speaker terminals. Non-powered speaker sees only voltage between terminals (difference) but ground referenced powered speaker might no... 
Class "D" amp? I do not have a clue. Do you?
Afc - Ref1000 can drive 2ohm delivering 40A. Size of power supply has nothing to do with it since 2" toroidal transformer at 100kHz can pass as much power as 10" toroidal transformer at 60Hz. In addition voltage doesn't drop since it is line and l... 
Class "D" amp? I do not have a clue. Do you?
Orpheus10 - I have Rowland Model 102 based on the same Icepower modules as mentioned Bel Canto S300 (and M300). It is very smooth and transparent (nice liquid midrange) but also very revealing. With new speakers (Hyperion HPS-938) I can finally he... 
directional cables?
Even if your piece of equipment is floating there is still return - most likely capacitive. Cell phone is getting this return thru your body (just a few pF). Radio signals are in fact induced in in the cable (since shield most likely does nothing ... 
directional cables?
It is worth to mention that with AC current electrons are not moving at all but rather vibrate. Given electron does not change position but electric charge does. 
directional cables?
"In direct current, the electrons do indeed flow in one direction, and thus "the load""Nsgarch - electric current is a flow of charge and not a flow of electrons. Electrons move very slow - at about 0.1mm/s (drift velocity). 
Digital Cable : Copper, Solid Core, Unshielded
Pani - Shielding is very important in digital cable because it prevents noise induced jitter and prevents reflections (that happen on impedance boundaries) by keeping proper characteristic impedance. Wire material is less important since at high s... 
amplifier power consumption
"The largest your budget allows. Even though the watts may be sufficient to run your amp, dynamics can still suffer."I agree with Face. Amp that consumes peak 600W, like mentioned Cambridge, does not take 5A sinewave current but short narrow pulse... 
Interconnect Help - Recommendation Please
One of the better values in $1000 used is Acoustic Zen Absolute - read reviews (foamed teflon, zero crystal silver with 1% copper). It is very open and detailed (transparent) but also very smooth. I use 0.5m XLR = paid only $600 but it was a barga... 
Why are server setups so costly relative to CDP's?
Tgrisham - I have Mac Mini + Airport Express + Benchmark DAC1 + Power Amp. It really cost me $100 (Airport Express) since I have/use computer anyway and My Benchmark DAC1 serves as a Preamp (has volume control). 
cd burning speed
Marakanetz - I had bad copies using 8x DVD burner on 16x DVDs. Apple explains that problem might be related to limited range of power adjustment of the laser. Imagine writing 52x CDR with 2x speed. Burner adjusts laser power on a special track (as...
