Default 24bit/192kHz Digital Crossover?

Given that 24bit/192kHz content is now readily available on Blu-Ray discs with the lossless audio codecs now on those films, is there a digital crossover that will support this definition? I am currently using a miniDSP, but even the highest end models are limited to 96kHz. Without starting a debate whether I can hear the difference between 96kHz and 192kHz (I don't care, so don't start the argument), is there either a DIY crossover, like the miniDSP, or a commercial one that I can purchase that supports 192kHz sampling rates?

Hi Frost
Blu ray HD audio content requires HDMI connection, this is due to copyright protection, spdif does not carry it.

heh heh, cheap 'n' cheerful.
Great for your HDCP free 24/192khz audiophile music downloads.

Ouch, I'd need 3 of those for a home theater application. Any DIY solutions (read cheaper?)?

Also it will not work for you with high definition audio content specifically from blu-ray if you want to keep it in the digital medium without DAD conversion taking place.

HDMI for high bandwidth copyright protection has to be involved to pass these new formats in a digital medium and unless some expensive proprietary security technology is involved after the hdmi input you cannot send full bandwidth data on in its original form over digital to external circuits.

On further examination the DEQx will not work with 24/192khz from an analogue source (processor outputs) anyway as it will only give you conversion to 24/96khz from an analogue source:

Technical spec's state "24-bit /96kHz ADC"

Right - the problem is how to get the high bitrate stream out of the player without the HDCP encryption. I don't think you can via HDMI. Maybe you can pick it up somewhere inside the player, but it doesn't seem likely.

As you don't care about any possible sound quality differences between 192 and 96, the cheapest solution would be stick with miniDSP and use ASRCs to downsample your 192 to 96 at the input.

I believe he was implying that he does not care about the technical arguments, he does not want to hear them. He simply wants to know that he has all the data in its original form, regardless of whether his human hearing could tell the tiniest difference between 48, 96 or 192khz. I can understand this.

I might be wrong but I believe the list of 24/192 blu-rays is extremely thin anyway. Ironically those that I have seen have been very low fidelity rock music remasters.

This has very little to do with fidelity. Looking at it rationally we know most Hi-Fi does not do full justice to well recorded 16bit audio, in most cases not even close. Despite this I can understand the Audiophile Nervosa coming through.
