I'm using Equalizer APO in Windows 10 to try and get the best audio I can from the Digital Concert Hall streaming site of the Berlin Philharmonic into my audio system which consists of a Bifrost 2/64 DAC, Kara F preamp, Aegir 2F amp, and restored Allison Two speakers. I also use a Midgard headphone amp with Hifiman HE1000se headphones. Archived videos from the Digital Concert Hall site stream audio in lossless FLAC at 24 bit/48KHz. The stream is accessed through browsers and they do not provide a player that allows selection of the WASAPI exclusive function. I'm using Equalizer APO with no filtering to attempt to bypass original/hidden APOs and I'm using the preamp function of the program for attenuation to protect against Windows limiter-induced distortion. A problem for me with the Digital Concert Hall stream in Windows 10 is that when "Stereo Hi-res" is selected, video and audio are out of sync. Using the "Channels Delay" control on the PEACE GUI effects panel, a 320 msec delay seems to perfectly achieve synchronization with video. My question: is the delay function likely to introduce distortion and/noise? It sounds good to me listening casually, but I'm going for the best audio I can get out of this system.
