![]() Using Win10 and ASIO for RME ADI-2 Pro, you can monitor CRC and other errors on the USB driver level and I did actually try to provoke errors. Isolate your DC filament supply if you have them in your DIY tube amplifier! No, wait, have EACH of your DC filament supply isolated! Do not share the B+ power transformer with the DC filament power transformer.Click to expand.Same here, never had any problems with USB data integrity even in extremely long measurement sessions, loopback recording at high fs, for hours. Have one isolation transformer each for all your electrical devices and be prepared to be blown away! A 1KVA isolation transformer is just overkill for them. Since the DAC and USD to SPDIF converter use less power, I can get a smaller VA isolation for the job. What’s next? Installation of the 3rd isolation transformer – 1 for the amplifier, 1 for the DAC, and 1 for the USB to SPDIF converter! Things become even better! Sibilance and high frequency glare got lesser! The system is more analog sounding than ever. The IT is going to stay in my audio system as a permanent resident!Īt a later stage in time, I installed another IT to separate the USB to SPDIF converter with the tube amplifier & DAC. Vocals stand out and have a more solid body to it. Background becomes darker and imaging gets better. ![]() I’ve an annoying buzz riding on my power line and it is gone after I installed an IT! Apart from the noise elimination, it actually improves the sound as well. ![]() You can use the PS Audio Noise Harvester, Audioprism Noise Sniffer, oscilloscope, spectrum analyzer, or even your own ears to do the measurement. Noise generated from the digital and analog sources are contained and prevented to pollute the mains and each other. ![]()
