Has anyone an idea how to get this roll-off mode selection implemented? It isn´t a bug report i can open but a feature request. Maybe one of the knowing in here can comment if it is even possible? This slow or sharp roll-off is affecting all sampling rates btw. -- Wombat Transporter - RG142

Yes, maybe - but only in the CD area. I have PWD for a week (got from a friend) I get somewhat bigger soundstage with PS Audio and more detailed presentation than with Transporter, but with Transporter I get much more precise bass and more focused sound (for better or worse) With high-rez

I don´t understand Apodizing exactly. I guess it is applying a resampling with a soft lowpass and no linear phase. So it surely chnages the sound and can get rid o pre-ringing like even a simple lowpass can. In the end it only smears and muddens the original at a margin you can influence. I

Well this type of filtering has been around for awhile. The DIY DAC that AMB designed using the Wolfson 8741 which has selectable filters, one will apply minimum phase slow rolloff which eliminates pre-ringing. You can see trace outputs at his site http://www.amb.org/audio/gamma2/ and then

Meridian owners are hoping and waiting that these new Apodizing filters will come to Meridian preamp. Some get to enjoy it now with it built into some of the DSP speakers and HD621 processor. Those into standard DACs can enjoy the same technoligy in the Perfect Wave DAC. It's cool to see this
