| Silver spades Total spade resembles roughly AWG10 and distance of 1/2". Copper 10AWG resistivity is about 0.001ohm per foot. 1/2" spade would have resistance of 0.000042 ohm. Silver spade would be 0.00004 ohm, while aluminum spade would be 0.00007 ohm. Such... | |
| Do Harbeth speakers really need a 4000 damping factor? Membrane motion braking current (Lenz law) passes thru speaker, wire, amplifier's output and the other wire. Would adding 0,002ohm (DF=4000) instead of 0.02ohm (DF=400) to speaker impedance make it sound different (damp/brake better)? Even if we... | |
| Speaker wire impedance? Speaker impedance? I suspect you measured wrong. Kimber 8TC is gauge 9 that is 0.0008 ohm/ft. In order to get 0.05 ohm you would have to have 31 ft cables. For 0.07ohm it would be 44 ft. Revel is likely concerned that additional resistance in series with speaker’s c... | |
| Unplated copper spades/banana Gauge 10 copper wire has resistance of 0.001 ohm per foot. Gold plating is typically 0.00001" thick. It adds additional resistance in order of 1 microohm (o.ooooo1 ohm). Perhaps there are other effects when signal is crossing boundary of two diffe... | |
| 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... | |
| Six DAC Comparison @audphile1 +1 | |
| 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. |
