It's on track so far For those who cannot afford the full amount a 20% deposit would suffice so we can allocate a Preamp for you. However to be fair to those who have already paid up the full amount, they will be placed first in the queue to receive their Preamp

cheers

I want to know if the built-in DAC can be configured to be non-oversampling and switch off the high pass filter for a nice non-ringing impulse response?

That does remind me: are the output DACs independent of the processing sample rate? In other words, can I process at 48 kHz and run my own oversampling filter to 192 kHz?

Why do such a fool thing? Just for kicks & grins I'd like to try a minimum-phase reconstruction filter. It'll cost a few clocks but nothing like the 100 Hz FIRs elsewhere in my system.

We weren't planning on doing anything like that as the ES9038PRO already provides 7 different OS filters. In any event even if we could override the internal OS filter and generate our own with the DSP it would chew up quite a bit of the DSP resources from the normal usage for crossover use.

Yes you can do something like that in Audioweaver. You can down convert to a lower sampling frequency to do FIR's and the up convert back
