| 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. | |
| Importance of clocking @greg_f You can try USB to Firewire adaptor (or cable). They are about $5 on Amazon - might work. | |
| Importance of clocking @greg_f I remember that Weiss DACs had Firewire. I had Firewire HDs with my old Mac computer and used them with the newer generation with an adapter. Advantage of Firewire was that it had, being extension bus, sustained bandwidth. Peripheral buse... | |
| Importance of clocking @greg_f There are two different ways of dealing with S/Pdif. One, very common way, is to adjust D/A clock to average frequency of incoming S/Pdif stream while another is to completely ignore S/Pdif clock, strip the data and send it to D/A conve... | |
| An argument for fuses and maybe power cables in power amplifier Linear power supply is really a primitive switcher operating at 120Hz. Current is drawn from the mains in narrow spikes of high amplitude, that become wider when load increases. In addition rectifiers become reverse polarized at the peak of the ... | |
| Importance of clocking Let‘s just say that my ears and reputable designers like Innuos, Esoteric et al disagree with you Disagree with what? I don’t question you can hear the difference, but I attribute it to electrical isolation that device brings and not the reclo... | |
| Importance of clocking AFAIK there is no error correction with asynchronous USB. Frames contain checksum (CRC field), but I’m not sure if computer resends the frame. In plain USB transfers device on receiving end sends back “negative acknowledge” (NAK) and frame is re... | |
| Importance of clocking @antigrunge2 What processor? The only one that can affect timing of D/A converter is in the DAC. It loads samples from the buffer into D/A converter at even time intervals. It also signals back when buffer is too empty or too full. Sending as... |
